DHDDouble-acting piston seals with integrated Back-up ring
Double-acting piston seals with integrated Back-up ring. Designed to guarantee excellent resistance in heavy duty applications minimizing the housing spaces, thanks to the integrated anti-extrusion tings allows large diametrical gaps. Particularly suitable for heavy hydraulic applications. Standard materials: PTFE compounds with nitrile rubber energizer and polyacetal resin anti-extrusion rings, also available in different combinations of materials depending on the application requirements.
