Can your company manufacture bespoke static Seal with the following specification? Seal internal diameter - 6.5mm Seal thickness - 15mm thick, 5mm height Seal Operating Temperature - 5oC to 40oC Seal material - preferably Polycarbonate but welcome your recommendation. Seal is static and used on rotating shaft with details below Shaft diameter - 6.5mm Shaft length - 18mm Shaft material - Chrome (It can be any other material that you recommend as long as it does not rust) Suggested Oring CS - 2mm The seal is required to prevent water leaking through the rotating shaft. Liquid is enclosed in the sphere-like structure of 35mm diameter. Sphere will retain liquid for up to 2minutes max then it is emptied. Human hand must be capable of turning shaft clockwise and anti-clockwise and seal still prevent leaking.
Hi there, I confirmed with our sales team that we received your request over email and they are reviewing your inquiry and will get back to you as soon as possible. Thanks for reaching out!
Hi Seth, in general, elastomers are good for COLD temperatures but NOT cryo-temperatures. Cryogenic temperatures is somewhat vague, but most consider it to be around -200°F. There are certain silicones or fluorosilicones that can seal around -100°F, but anything colder than that is when we would move towards spring energized teflon seals. If you have an active project or anything that needs engineering guidance, you can reach out to start a conversation at GFSsales@gallagherseals.com. We have two full-time seal engineers that can help with complex seal designs (or basic ones as well). Thanks!

What is the best type of o-ring for cryogenic applications, such as a vacuum plug?
