Technical Properties

A209 SINGLE ACTING BUFFER SEAL

A209 buffer seal is designed to be used for hydraulic cylinders and rod applications as the first sealing element to reduce pressure peaks and protect the secondary seal.

A209 buffer seal is manufactured with high specification 92 shore ALP PU compound and a TPE backup ring to prevent extrusion.

A209 buffer seal offers high wear resistance, low friction and good protection for the secondary seal during pressure peaks.

A209 is not to be used as main sealing element and we recommend to use with our U rings combination such as A151, A154 etc.

Wide range of metric and imperial dimensions available on Exstock.

ALP A209 rod buffer seal to be used safely for construction machinery, moving platforms, forklifts, agricultural machinery, earth moving machinery, cranes, injection moulding machinery and any standard cylinders.
