Rubber Expansion Joint - Single Arch PTFE Lined – Style ETWA.

Single Arch Teflon Lined Style ETWA is composed of a rubber body and loose carbon steel flanged ends connections (or retaining rings/females), these joints become an excellent solution to compensate thermal and/or mechanical displacements with low spring forces.

Installation Instructions:

The good performance of rubber expansion joints depends on the correct installation.  The screws must be tightened intercalately to assure rubber uniform compression, just the necessary amount to produce full sealing, not being recommended to exceed 85% C.
