DESCRIPTION

The MNBR profile is a compact rod seal designed to act as a buffer seal for the primary rod seal. Molded in PTFE with a rubber energizer and nylon anti-extrusion ring, this seal absorbs the shock of pressure spikes to protect the primary rod seal. As a buffer seal, the MNBR profile provides a majority of the rod sealing performance while allowing fluid to bypass onto and energize the primary rod seal. Fluid located between the MNBR profile and the rod seal will relieve back into the cylinder upon rod retraction to prevent .
