PREMIUM BUFFER SEALS
These Premium Buffer Seals are used for extreme pressure spikes and for larger rod applications. They’re designed to provide secondary sealing and vent back pressure in low friction, high duty cycle applications. They also improve the rod seal’s life. They’re recommended for large rod diameters.
They're filled with PTFE and Nitrile.
