Features and Functions

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.
