Piston seals, type T18

This double-action compact piston seal consists of a profiled nitrile rubber sealing element which provides both static and dynamic seals. The rubber element is supported by two back-up rings. The back-up and guide rings are designed with a slot. Due to the low profile of the guide rings, assembly on one-piece pistons is very easy. The ZA sleeve can be interchanged with most common sizes of other compact double-action piston seals.
