O Rings
O rings is a rubber parts with a round cross-section used as a static seal or gasket. We have over 15 years experience producing o rings,which made according to china GB standard for chinese market,and also international standard of AS 568A and JIS B2401 for oversea market.We have various materials and hardness for customer's option, include FKM, Nitrile, Silicone, EPDM,ACM, Butyl,Flour Silicone, Alfas, Polyurethane , Neoprene etc.
Hardness :Shore A 30-90
Tolerance:Can be +/-0.01mm
Size:ID2mm-1500mm,We can make Mini orings which used on lighter, for example 1.2(ID)*0.6(C/S), 0.8(ID)*0.7(C/S).
Colours: White, Black, Grey, Yellow, Blue, Green, Brown.
Nitrile(NBR,Buna-N) O rings
The most common elastomer Used For Industrial Grade O-Rings,Metric and Inch are available.
oil-resisting property better than other O rings,commpatible With Most Mineral Based Hydraulic Fluids
With A Working Temperature Range From -40°C To 120°C.
Viton(FKM/FPM) O rings
Excellent resistance to petroleum products and other chemical fluids. Very good high-temperature performance. Fluorocarbon elastomers make up the most widely used seals in the automotive industry.
With A Working Temperature Range From -40°C To 220°C.
Silicone O rings
It is commonly used in home applicance,like cooker,heater,mixer,food processer,it is non-reactive, stable, and resistant to temperatures from −55 °C to +300 °C,and have competitive price.
We have FDA catalog d O ring,it is non-toxic food grade.
EPDM O rings
This o rings is excellent resistance to weathering and ozone, water and steam, with good performance in castor and some phosphate ester based fluids.
Neoprene O rings
Good aging characteristics in ozone and weather environments, along with abrasion and flex cracking resistance.
Can be compounded for service temperatures of -40°C to + 130°C
Butyl O rings,Aflas O rings
Butyl o rings is one of the most robust o rings. Butyl rubber is a harder and less porous material than other elastomers, such as natural rubber or silicone, but still has enough elasticity to form an airtight seal.
Aflas o rings is excellent resistance to acids, bases, water and amines. Widely used in oil fields,
A unique fluoroelastomer based on a copolymer of tetrafluoroethylene (TFE) and propylene (P) was developed by Asahi Glass (Japan) and sold under the AFLAS trade name.
