Description

A weeping cylinder is the most common reason a machine is taken out of service, and it is almost always a seal rather than a barrel or rod problem. We hold and source complete kits — rod seal, piston seal, wear ring, wiper, O-rings and back-up rings — in NBR, polyurethane and PTFE-bronze depending on operating temperature and pressure, rated to 350 bar and covering the main excavator and loader brands. Quote by machine model and cylinder bore/rod diameter, or send the old seal set and we will identify the profile.
