We primarily stock rod buffer seals, though piston buffer seals are available upon request. Buffer seals are commonly used in combination with another rod or piston seal, typically a U-cup style seal. Buffer seals in rod applications are designed to absorb pressure fluctuations when working under high-load conditions, this increases the lifespan of a rod seal. |  | ||
