Brown Yellow Green Blue Nitrile Rubber O Seal Ring Supplier for Water Meter
NBR(nitrile butadiene rubber)
*Service Temperature
For NBR the service temperature can be designed from -50 C to 100 C or up to 120 C depending on
different acrylonitrile content and formula.
*Application
NBR compounds have excellent resistance to abrasion, non-polar oils and solvent, water and permeation
(higher acrylonitrile content will be better). NBR also can be used in conditions of dilute acids, alkalis and
salt solution at low temperatures.

Rubber O Seal Ring Product introduction
The standard of O-rings mainly includes: national standard GB1235-76, national standard
GB3452.1-92; Japanese standard PTYPE, GTYPE, STYPE, SS/VTYPE, FTYPE; American standard
AS568, British standard series; European standard series
O-ring technical requirements include appearance requirements,
dimensional requirements, and
material physical performance requirements.
Appearance requirements in line with GB/T3452.2-2007
Material requirements are in line with HG/T2579-2008
Dimensional requirements are in line with GB/T3452.1-2005
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.
