Our A114 double acting piston seals consist of 4 pieces.
Consisting of 1 NBR ring, 2 POM support rings, and 1 thermoplastic sealing ring, A114 piston seals are especially preferred for applications with position accuracy.
One of these applications is hydraulic mining poles.
Thanks to the support ring in the set, A114 seals which perform at high pressures can be preferred in heavy-duty applications.
