BR Rod Seal

Descriptions

The BR profile is a compact rod seal designed to act as a buffer seal
for the primary rod seal. As a buffer seal, the BR profile provides the
majority of the rod sealing performance while allowing fluid to by pass
onto and energize the primary rod seal. Fluid located between the BR
profile and the rod seal will relieve back into the cylinder by flowing
past the BR profile’s flexible static side lip and slotted pedestals. This
relieving or check valve function allows the BR profile and primary rod
seal to work as a sealing system without the danger of developing a
pressure trap. As a sealing system, the BR profile and primary rod seal
provide optimal performance in the most difficult applications.
