Product Description

Metal O Ring

There are three types of metal O ring. They are non self-tightening type, self-tightening type and inflatable type. 

Metal o-rings seal mechanism similar to flat mat, rely on the deformation of the ring after preloaded back stretch, make the sealing surface produces a certain amount of stress.The material yield stress can make hollow ring surface, fill seal groove on the uneven, and compensate the sealing surface is not parallel to achieve sealing.Is the elasticity of the hollow ring ring and groove seal face tight fit and seal.So in the main manufacturing process of lighting tube o-rings, cutting blanking, bending, the pier head, butt welding, file repair grinding, calibration, polishing, to keep the surface finish requirement.In a sealed lively media, also should be electroplated or spraying high ductility compensation materials.Of course, to match the o-rings flange surface also have the same requirements.
