"When age speaks, wisdom listens." Thanks for your very informative video!
6 years on it 's still a clear and simple guide to changing the gas cylinder on an office chair. Thanks!
Hi, it's me again. A tip your viewers might find useful:
I had a devil of a time getting the old gas piston out of the base of the chair. It was an old chair and I was beginning to wonder if the old gas piston was fastened in place somehow (it wasn't). I tried using a pipe wrench as you suggested (for your viewers: pipe wrenches are designed to grip smooth cylinders, like pipes) and a whole lot of leverage, but it ended up only making the pipe wrench gouge a groove in the metal of the old gas cylinder.
A machinist friend gave me a tip that was the solution -- point a blow dryer or heat gun at the old gas piston where it enters the chair seat. I let the blow dryer run for about 20 minutes. After that the pipe wrench worked.
My guess is that the blow dryer simultaneously heated up the metal of the old gas piston, which made it expand, and also softened the plastic of the socket that it was stuck in, so the expanding metal stretched the socket a bit, and maybe broke whatever effect (pressure seal?) that was making it impossible to remove.
Thanks again for your useful video!
You deserve a reward for the best man in the office chair industry 😂 this is the only video that I found that showed how to do this the correctly and very descriptive in that , I’ll be sure to buy my parts from you when ever I need any thank you
This guy is the Mike Erhmantraut of swivel chairs. Thanks for the very thorough, straight to the point videos
Excellent, thank you. I'd watched another video instructing us to just tap the base off with a mallet - luckily I saw this as well and when I checked my chair definitely has the clip holding it in place as in this video. Glad I found this before causing any unnecessary damage. Much appreciated sir.
I didn't know you could replace them! Thanks for taking the time to thoroughly explain it!
I love my chair but it has been driving me crazy with it slowing sinking. I'm really glad I found your video. Thank you, I'll give it a try!
A well thoughtful and complete explanation of gas cylinder replacement. Bravo!
About $15 to DYI or buy a new chair.
Very useful video, it got me started on the right tract. But I need to point out some omitted information.
When ordering new parts, the dimensions listed are an "outer cylinder" and "inner cylinder." By these definitions I would like to elaborate the following:
1:40 the wheelbase is removed and along with it, is the "outer cylinder," the black cylinder sticking out of the wheelbase. When you order a new pneumatic system, that is one of the new parts that will come with it and will be the color you are ordering and will be covered by the telescopic skirt anyway. Part websites will give a diameter or "width" around 1.83" ~ 2.15". Make sure to measure that and remove it from the wheelbase. This might require a rubber mallet or to put a wood board between it and a regular hammer and set it up-side-down on a pair of saw horses to knock it out.
2:30 Don's length measurement method is confirmed correct here and what he is measuring, he calls the "gas cylinder body" that replacement part on websites will be called "inner cylinder." The diameter or "width" of that part will be around 1.1". The parts I looked up had no variation on that width which is probably why he omits this information in the video.
The new system you order when it comes in, will also come with the rubber stopper, 2 metal washers, a bearing plate, and a new clip and washer. No need to order those replacement parts. When you remove the "inner cylinder" from the mounting plate on the under side of the seat, you may also have to forcibly knock the cylinder out of the plate. The new system will be held by friction between the wheelbase and mounting plate under the seat and its tightness is reinforced every time you sit down.
Thank you for those clarifications!
I can't tell you how grateful I am for this video. Thank you so much!
The only one who shows how to properly remount the bolts, rubber and that white thing with metal balls around it. I was inches away from throwing everything in the thrash. THANK YOU, GOOD SIR!
I want him to be my father, this was the most helpful thing i've ever watched in my entire life.
as we say over here in Australia ONYA MATE

Terrific! thanks for making this video!
Very helpful and much better then other CZcams vides about the gas pistol and how to replace it thank you
Don you are an angel! Great instructions.
Very informative video on how to replace a gas cylinder, also some what reveal to me how the gas cylinder chair works!
nice explication for replace the gas cylinder ,, congrats for you mr.
This is a great video and it really helped me a lot. Thank you very much for educating me.
Brilliant informative video!! Thanks from Yorkshire!!
Nice detailed demonstration.
Thanks Don. Had to abandon my 16-oz hammer and purchase a 4-lb mallet. After a dozen taps on the Lift Off tool, the cylinder came free. Thanks for the video!
Good Kevin, whew! I'm sure that's a relief.
Don
Thank you so much! This was super easy to measure and it will cost me like 20 EUR to replace it! :)
"The collar is not part of the gas cylinder" - I was hitting mine for a good 20 min then took the plastic guard off and realized it was welded lol. Thanks for the video.
Very nicely nerrated one. Thank you sir.

Thank you!
thank you sir !!! a ton
When measuring the length do you have the cylinder all out or in?
thanks for the vid
انت كفووووووووووو
i am ardic
You are a good man ..thank you now i sup
Thank you for an excellent video...now how do I know that gas cylinder is bad. I'm missing the washers and the clip. We just measured the cylinder and it's 5 1/2", yes its's a child's chair....It's a neat swivel chair and I'd like to keep it...Also I have a beautiful adjustable table that needs fixing as well. Are you able to help us there..I know we need to replace that cyclinder too it doesn't rise. I just subscribed.
I just bought a chair that has a very short lift, can I change it for a higher one? Tha chair is a Realspace® - Big & Tall Chair - Axton chair.
how do I know if its the cylinder or the column that needs replacing?
I have a nice saddle seat chair but the bottom part of the chair hurts my ankles and i want to replace it, if i buy the bottom spare part will it fit?
The gas cilinders are all the same arent they?
Will do more research on this.
Please lay chair down a snap a bottom photo. Yes, most are the same.
Don
Thank you, this was very helpful. I just watched a half dozen videos on how to replace the gas cylinder on an office chair and *none* of them mentioned the length issue. I measured mine and it's 8 1/2" exposed surface, so I assume I should order a 9 1/2" or as close as I can get. Your site lists a 9" cylinder and a 9 3/4" cylinder. If the exact length is not available, Is it preferred to get a slightly shorter or slightly longer cylinder?
I'd order the slightly taller.
Don SCP
@@swivelchairparts Thanks.
Inches in Australia?
There are two types of cartridges available, the one you show in this video with a clip on the bottom, and a press fit type. What is the one you show in this video called? I need a new one, but don't want to order the wrong type. Thanks! Agree with several of the others, great video!
Jim, We call the clip one a "COM" CYLINDER (abbreviation for complete). It includes the COLUMN, 6 PIECE BEARING SET, and the GAS CYLINDER. The other one we just call a CYLINDER.
swivelchairparts Thank you! Now I know how to search for the right one. It looks like mine takes a replacement that is 1 7/8" at the base, and 1.1" at the seat. So far haven't found any 1 7/8' units.
Jim O'Dell The 1 7/8" takes a 2" COM. The base hole is slightly smaller so that the COM will not fall through and hit the floor.
Good old fella
What's a newspaper?
My chair has a built-in column I'm replacing the gas cylinder of my chair for the first and I'm wondering if it's safe to remove the column of a brand new gas cylinder for it to fit in my chair's built-in column.
Yes, it will be perfectly safe. Read
@@swivelchairpartsomg! I didn't expect a reply. Thank you so much! ❤
so you sell replacement ball bearings ? for the end
Yes. It's a little kit contain the 6 needed parts for about $5. on Amazon. Their numbers for search--B00II4V2Y8

Hi.
I have read that those cylinders can explode and hurt people in very rare cases... As a pro on that area is that even possible, i mean, if this by any chance explode sometime, is there suficient pressure inside to hurt someone?
Sergiocrivelin, I read that several years ago some Asian fellow claimed that occurred but that has never been substantiated.
Don
Seems unlikely. It is pressurized, but in order to explode, you'd need to somehow increase the pressure while maintaining a seal (maybe if you heated it up with a torch or threw it in a fire.)
If you break the seal, however, the air will come out through the hole. It might be forceful, but it should just be a blast of air (and whatever lubricants might also be inside - so it could hurt if it got in your eye.) But I can't imagine it exploding.
My moving company somehow lost the parts that hold the wheel base to the "Spindle"(washers, clip, etc)
Where can I get replacements.
We have them at swivel-chair-parts.com/BearingKit.html
Do I need to measure the width of the travel bar that extends? Mine is 1.25 inches, and not 1 inch like the piston I want to order, which is 1 inch and 2 inch widths for the 2 bars. (not talking about the 3rd skinny thing deep inside.)
Hello,
that part (about the thickness of a pencil) is not necessary to measure
@@swivelchairparts I mean the part that is 1 inch thick (it's the 2nd biggest tube of the piston). The tube (in the piston I'm replacing) is ~1.25 inches. The one I'm ordering says 1 inch though, not 1.25 inches. Will it fit? The biggest tube matches measurements; 2 inches wide.

When measuring with an accurate machinist caliper it will measure 1.102". Sometimes called 1" up to
1 1/4" and as well as 27.99mm. And yes, I believe ours will fit.
I stupidly forgot the newspaper ... now I have a greasy mark on the carpet.
Could I order a cylinder that is a little longer than the one already there and it would still work? I would like the chair to be able to rise a little higher.
Sure, this is the web site link--www.mychairparts.com/gas-cylinders.html
I have a task chair mfg in 1996 by Eckadams Company. I recently bought 2 from a local site for my home office. They were both in excellent condition. From what I can see it looks like the clip came off the cylinder and the piston rod is sticking out of the bottom. Not sure what I should order.
Hi Don, How can I order just a washer and a clip for the bottom of the chair?
Go to Amazon.com and order an inexpensive bearing kit from the "search" B00II4V2Y8.
@@swivelchairparts How can I send you pictures of my chair and the parts I ordered? I could not find the part you recommended.
Sorry I found the part and it is what I ordered. But it will not fit.
email us @mychairparts.com or text to 405.696.7682 or phone talk 405.608.4222.
No mention of how to measure the piston diameter?
Hi I unlocked the clip and the piston went inside the gas cylinder .. is there anyway i can get this out ?
Yes. If cylinder is still in the mechanism, trigger the lever a little at time until it comes out not more than an inch or so and reinstall the clip. If out of mechanism, strike button on a table top to extend it not more than 1 1/2".
Hi Don, I really hope your doing well in life my friend good man....thank you so much to show how to measure a cylinder chum! YOur a good man! I hope they solved the mysterious death of Julie Mitchell! So when I order the cylinder it looks like I'm getting the column? I'll just hammer out the column from the base obviously and use the new one!
How do i find that EXACT cylinder? the reason i ask is because my chair has a 1" diameter cylinder and the piston is 1/2" in diameter and everywhere i look everything is 2" cylinder with 1" piston
Please read my email sent to you.
Don
Title should be "Office chair cylinder Sage speaks"
How do you remove the gas strut, I can not access the top of it to hammer it out?
It TWISTS off in any direction you like but it takes a 15" or longer plumbers pipe wrench or rent a removal tool from us for $6.50.
