Product Parameters

 

1. Rubber O-ring Introduction
It is rubber ring with O-shaped cross section, it has high elasticity, insulation and long service life.
It is easy to manufacture, inexpensive and reliable, so it is commonly used in machinery manufacturing,
automotive,electrical, medical and other industries,and plays the role of sealing, insulation, cushioning,
fixing, etc. Therefore, rubber O-ring is one of the most commonly used seals in global machinery.

2. Raw Material Selection
Rubber O-ring has a variety of raw materials. Different materials have different properties and prices. 
The order of material prices is: NBR<SIL<EPDM<CR<ACM<FKM<HNBR
We should choose the appropriate material according to its use environment.

The following table is the main characteristics of the material. If you want to know more about a
material, please feel free to contact us.

 

Rubber	Characteristic	Application
NBR	Oil resistance	Oil tank, lubricating oil tank, mechanical equipment, use environment without special requirements
EPDM	Strong water and steam tightness	Water pump, bathroom, automobile brake system
SIL	Good elasticity, wide temperature range, wide practicability	Electronics, food and medical industry
FKM	High temperature resistance, chemical resistance	Automobile engine, fuel system, mechanical equipment of chemical plant
ACM	High temperature resistance (weaker than FKM)	Automobile engine, fuel system
HNBR	Low temperature resistance	Air conditioning and refrigeration industry
CR	Flame retardancy	Ozone environment, flame retardant products
