FlexPVC Demonstrates the differences between the D (long) and A (short) versions of the inside ext.

There are two different versions of the inside pipe extenders. The D version is longer and a bit more expensive. But it will fit a wider variety of pipes, especially those out of spec. The A version is a little cheaper but it's right on the money on the spec. If your pipe has a thicker wall or you buy from multiple PVC pipe suppliers the D version may work better for you. But both work equally well when glued into an existing pipe to send it. The primary use of this product is when a pipe breaks or is cut off flush with the floor, concrete, wall etc and there is no other way to attach to it.
