O-ring

The O-ring produced by Huayi Rubber has good sealing performance and precise dimensions,making it the choice of many water and gas valve manufacturers both domestically and internationally. In addition, the O-ring is suitable for installation on various mechanical equipment, serving as a seal in different liquid and gas media at specified temperatures and pressures, and in static or moving states. Various types of sealing products are widely used in machine tools, ship engineering, automotive industry, aerospace equipment,metal lurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery,petroleum machinery, plastic machinery, agricultural machinery, and various instruments and meters. TheO-ring is generally instal led in a groove with a rectangular cross-section on the outer or in ner circle toplay a sealing role.

The O-ring can still play a good sealing and shock absorption role in environments such asoil resistance,acid and alkali resistance, wear resistance, and chemical corrosion resistance. Therefore, O-ring seals arethe most widely used type of seal in hydraulic and pneumatic transmission systems.
