Tri-Flex Loop®

The safest and most reliable means of absorbing up to 24" of movement resulting from thermal changes, random seismic shifts, and misalignment in a piping system. It also dampens vibration and reduces the transmission of noise. Tri-Flex Loops are designed to be pressure tested 1.5 times their maximum rated working pressure and manufactured with a 4:1 safety factor. The Tri-Flex Loop® eliminates the need for the added installation expense of traditional long length pipe loops and its compact design saves valuable space.

Tri-Flex Loops do not impose additional thrust loads on the piping system and thus eliminate the need for costly anchoring or thrust blocks while also eliminating pipe guides required by traditional pipe designs such as expansion pipe loops or expansion joints.
