Not Easy To Corrode And Waterproof Polyurethane Sealing Ring Air Filter Seal

1. product introduction

The rubber seal ring is an annular cover composed of one or several parts, which is fixed on a ring or washer of the bearing and contacts another ring or washer or forms a narrow labyrinth gap to prevent the leakage of lubricating oil and the intrusion of foreign objects. Rubber ring mainly includes: rubber O ring, sealing rubber ring, fluorine rubber ring, silicone rubber ring, waterproof rubber ring, conductive rubber ring, retainer ring rubber ring, insulated rubber ring, stellate rubber ring, nitrile rubber ring,silicone rubber ring, polyurethane rubber ring. Rubber ring is a kind of effective and economic practical sealing element. Compared with other rubber ring products, rubber ring has many advantages:
(1)Simple structure, monolithic groove design reduces the parts and design cost, the design is compact, reducing the size of parts.
(2)Easy to install and reducing the risk of make mistakes.
(3)Standardization: a large number of standard size product in the world can be
supplied from stock, convenient maintenance and repair.
(4)For many occasions,the dynamic or static seal, single or double action.
Rubber ring almost can seal liquid or gas medium by choose the rubber material,
whether in standard or special occasions.
