DESCRIPTION

The DYR profile is a compact rod seal designed to act as a buffer seal for the primary rod seal. As a buffer seal, the DYR 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 DYR profile and the rod seal will relieve back into the cylinder by flowing past the DYR profile's flexible static side lip and slotted pedestals. This relieving or check valve function allows the DYR 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 DYR profile and primary rod seal provide optimal performance in the most difficult applications.
