Polyurethane seals is one of the most commonly used elastomer in most of the industries, when high levels of abrasion are present. This abrasion resistance is combined with high load & impact bearing capabilities that make polyurethane the material of choice for a number of machines and other engineering products.
PU seal: Hydraulic & pneumatic seals like piston seals, rod seals & wiper seal are available in all standard sizes. We also supply non-standard size and extra big size polyurethane seals.
This polyurethane seal is u-cup for rods & pistons.
