Description-NBR O-Ring Seal:
Rubber O-ring seals
O-ring rubber seals are available in a very wide range of gasket and o-ring types, including natural rubber as well as a large array of other elastomer and compound products.
Nitrile O-ring seals
Against water, gasoline, petroleum oils, crude oil, propane and some hydraulic fluids
Silicone O-ring seals
Good resistance to ozone, acids, water, and decent resistance to weathering and heat, making them great for outdoor applications.

2.O-ring size calculation: outer diameter = inner diameter + 2 x wire diameter (OD = ID + 2x CS).
3.The purpose of using O-ring seals is to prevent leakage and loss of liquids or gases.
4.O-rings are the most commonly used type of seal because of their simplicity, convenience, and small installation space. As long as the groove design and material selection are correct, and the operating conditions are within the temperature range of the rubber material, the seal can have a long-term sealing effect in the static or dynamic seal.
Our main products are: O-ring, X-ring, Y-ring, D-rings, rubber flat washer, ED rings, rubber strips, rubber ball, all kinds of skeleton oil seal and stepseal, polyurethane oilseal, pneumatic seals and Mechanical Seal all kinds of rubber parts for the design according to customer request.




Q. What is your standard packing?
A: All the goods will be packed by carton box and loaded with pallets. Special packing methods can be accepted when needed.
A: Generally it is 1-2 days if the goods are in stock. or it is 5-10 days if the goods are not in stock, it is according to quantity.
A: Yes, we mainly use ASTM D2000 standard to define the quality of the rubber materials, and tolerances as per ISO3302, ISO2768, etc.
A: NBR, EPDM, SILICONE, FPM(FKM), NEOPRENE(CR), NR, IIR, SBR, ACM, AEM, Fluorosilicone(FVMQ), FFKM, Liquid Silicone, Sponge, etc.
A: It depends on which model, we produce more than 2500 tons of rubber materials per month.
