Trico - Expansion Chamber
Trico Equalizer Expansion Chambers are designed to absorb surges and prevent pressure build-up in closed systems. A rolling Viton diaphragm provides a variable volume that, when properly sized, maintains oil housing pressure at or near zero PSI — extending seal life and helping prevent leakage. The stainless steel body also protects the integrity of closed systems by eliminating the exchange of air between the chamber and the surrounding atmosphere. Available in four models with thread sizes from 3/8" to 3/4" NPT, including a vent hole variant for specific installations.
