Black Colored Rubber O Ring Wear Resistance Most Commonly Used Nitrile 90 Shore

Black Wear Resistance Most Commonly Used Nitrile 90 Shore Rubber O Ring

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.

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.

NBR (Nitrile Rubber/Buna-N) material

NBR Rubber Features:

Nitrile rubber (NBR, Buna-N) provides excellent resistance to petroleum oils as well as

mineral and vegetable oil. Nitrile rubber also offers strong resistance to heat aging - often

a key advantage over natural rubber.

Nitrile rubber performs well in carburetor and fuel pump diaphragms, aircraft hoses, seals

and gaskets as well as oil-lined tubing. Due to its versatility, nitrile is used in applications

involving not only oil and fuel resistance, but those applications requiring resistance to heat,

abrasion, water, and gas permeability.
