A113 fabric piston seals are three-piece double-acting piston seals with two POM support rings and a special NBR ring.
Unlike other similar piston seals, the dynamic surface of the A113 NBR ring is reinforced with a fabric produced by a special method.
This product is particularly recommended for special fabric mining applications that perform better in water-containing fluids.
Since it does not absorb water in the fluid, unlike its alternatives, there is no change in volumetric and surface quality.
This ensures consistent performance. The fabric section also improves fluxion and friction properties.
