Custom CNC turning V type TPU PU polyurethane sealing ring

The surface roughness of polyurethane V-shaped seals is a critical quality indicator for sealing performance. We manufacture polyurethane seals for renowned seal manufacturers. The polyurethane V-shaped combination seal is a multi-seal set consisting of a pressure ring, a support ring, and one or more V-shaped seals (made of polyurethane, fabric-reinforced, or rubber). It is suitable for sealing piston rods and pistons of hydraulic cylinders with open grooves and reciprocating motion. Depending on the sealing application, it is designed in two types: shaft seals (piston rod seals) and bore seals (piston seals)
