rubber O ring, O-ring

5.Other Range of Material: Besides above range of polymers CRP supplies 'O' rings as per customer's specification and application requirements. Nitrile (NBR), Natural Rubber (NR), SBR, some of major materials being used are - Neoprene, EPDM, Silicon, Viton (FKM), HNBR, Fluoro Silicon (FVMQ), Polyurethane (PU), etc.

4.'Crown' 70 EPDM: This group of material have very high performance to resistance in hydraulic fluids with glycol base, break fluid, hot water. Suitable in hydraulic systems using fire retardant hydraulic fluids of groups HFC and HFD. I has very good resistance to ozone, aging and weathering. Temperature range for use -50o C to +150o C.

3.'Crown' 80 FKM: Widely used in applications for chemically aggressive media & high temperatures up to 300o C.

2.'Crown' 0 NBR: A special material mainly suitable for higher pressures in dynamic conditions. This polymer has excellent resistance to friction, swelling in hydraulic fluids, superior water resistance (Hot water up to +100o C). It can used at extreme high pressures as static seals with zero leakage.

1.'Crown' 60 NBR: The standard material, having excellent perform to seal in mineral oil, Hydraulic fluids with mineral oil, greases & fuels. It has very good elasticity, better cold flexibility down to -38o C, best gas permeability, low compression set, and withstand static pressure up to 100 bar.

The 'O' rings are ring shaped seals of circular cross section. They are having widest range of sealing applications such as in static situation, esistance against fluid and gaseous media, dynamic sealing element for axial, rotating & oscillating movement. To cover most possible technical specifications and applications, 'Crown' 'O'rings are manufactured in four different qualities of material.

O-ring sealing tips

The O-type sealing ring is a rubber sealing ring with a circular cross-section. Because its cross-section is O-shaped, it is called an O-type rubber sealing ring, also called an O-ring. It began to appear in the mid-19th century, when it was used as a sealing element for steam ...

The function of O-ring seal

The O-ring is an extrusion seal. The basic working principle of the extrusion seal is to rely on the elastic deformation of the seal to cause contact pressure on the sealing contact surface. If the contact pressure is greater than the internal pressure of the sealed medium, ...
