Heat Resistant Black EPDM Rubber O Rings for Gas Valves with Excellent Ozone Resistance for Automotive Tank Seal

Heat Resistant Black EPDM Rubber O Rings for Gas Valves with Excellent Ozone Resistance for Automotive Tank Seal

1.The O-ring is an annular seal having an O-shaped cross section, the size of which is determined

by the inner diameter ID and the wire diameter CS.

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.

EPDM material

EPDM Rubber Features:

EPDM rubber is a high density rubber primarily used for outdoor applications. It has

dynamic and mechanical properties between natural rubber and synthetic rubber.

Do not use EPDM if continual contact with petroleum based products is required.

Not recommended for usage in food applications or those that are exposed to aromatic

hydrocarbons.

O-ring application range:

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.
