DUL

Description

The DUL profile is a double-piston piece suitable for different pressures and high dimensional tolerances of the limit and lack of smoothness of the surface. This type of profile consists of two types of polyurethane connected to each other. The inner ring is used as a reinforcement, which is a type of polyurethane with low hardness to ensure the proper functioning of the seal in different pressures and flexibility and reduction of compression set. The outer part of the seal, which is responsible for sealing, is made of harder polyurethane with higher anti-wear ability.
