Unalon Style 112 / 113

DESCRIPTION
Unaflex "Multi-Purpose" PTFE Expansion Joints styles 112 and 113 are solid-molded of PTFE and specially designed to withstand the higher pressures and temperatures in today's piping systems. Their design allows a shorter face-to-face dimension, making them ideal for installation where space limitations are a factor. They are lightweight in design and corrosion resistant. Available in sizes 1" to 48" I.D. and for temperatures ranging from -300° F to +400° F.
