Expansion Chambers
Equalizer Expansion Chambers are designed to prevent pressure increases in closed systems. A rolling diaphragm provides a variable volume that, when properly sized, maintains oil-housing pressure at or near zero PSI. The reduced pressure will extend seal life and help prevent leakage. Expansion chambers also protect the integrity of closed systems by preventing the exchange of air from the chamber to the surrounding atmosphere. A choice of thread sizes and capacities offers flexibility to the user.
