K48 Hydraulic piston seals

K48 is a four piece double acting heavy duty piston seal which consists of one TPE profile ring, one elastomeric nitrile rubber to preload sealing element and two thermoplastic backup rings. TPE profile ring has superior abrasion resistance properties and K48 is a preffered sealing solution for rough countersurfaces.

Advantages

High wear resistance
High extrusion resistance
Good performance in high and variable pressure
Long service life
High performance in water-based oils and on rough surfaces
Suitable with long term locked systems
