About Oring

O ring is circular sealing elements with circular cross-sections, may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. O-ring(Viton O ring, PTFE O ring...) selection is based on chemical compatibility, application temperature, sealing pressure, lubrication requirements, durometer, size and cost. We offer you a range of elastomeric materials for both standard and special applications which allow the O-Ring to seal practically all liquid and gaseous media.

Application:

Used in erospace, automotive, chemical, petrochemical, chemical, food industry, biotechnology, clean water, machinery industry, sewage treatment etc.

Used in pumps and valves, reactor vessels, mechanical seals, filters, pressure vessels, heat exchangers, boilers, pipeline flange, gas compressors etc.

O-rings are suitable for mounting on a wide range of mechanical equipment and function in a static or moving state at specified temperatures, pressures, and in different liquid and gaseous media. In the machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various types of instruments, a large number of types of seals are applied. element. O-rings are mainly used for static and reciprocating seals. For rotary motion seals, only for low speed rotary seals. O-rings are generally mounted in a groove with a rectangular cross section on the outer or inner circle to seal. O-ring seals still have good sealing and shock absorption in oil, acid, alkali, grinding and chemical corrosion. Therefore, O-rings are the most widely used seals in hydraulic and pneumatic transmission systems.

O-ring specifications and standards:

O-ring specifications are mainly UHSO ring specifications, UHPO ring specifications, UNO ring specifications, DHO ring specifications, piston rod O-ring specifications, high temperature O-rings, high pressure O-rings, corrosion resistant O-shape Ring, wear-resistant O-ring.

The standard of O-rings mainly includes: national standard GB1235-76, national standard GB3452.1-92; Japanese standard PTYPE, GTYPE, STYPE, SS/VTYPE, FTYPE; American standard AS568, British standard series; European standard series

O-ring technical requirements include appearance requirements, dimensional requirements, and material physical performance requirements.

Appearance requirements in line with GB/T3452.2-2007

Material requirements are in line with HG/T2579-2008

Dimensional requirements are in line with GB/T3452.1-2005
