DESCRIPTION

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

As a sealing system, the MYR profile and primary rod seal provide optimal performance in the most difficult applications.
