Good Oil And Fuel Resistance NBR Quad Ring For Static And Dynamic Applications
NBR Quad Ring Material Description
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.

Quad Ring Product introduction
A variation of the standard O-ring, Quad-Rings have an X-shaped cross section suitable for sealing a range
of static and dynamic applications. This provides higher sealing efficiency and lower friction than conventional O-Rings.
Recommended for low speed reciprocating or oscillatory motion if O-Rings twist.
Provides lower friction than O-Rings and Square Rings.
Quad Ring/X-Rings are interchangeable with O-Ring sizes and glands design.
Available in the same size standards and custom sizes as O-Rings.
Readily available in USA AS568 standard sized NBR Buna-N and FKM.
Not recommended for pressures >500 psi.
Quad Ring/X-Rings may not be available in all compounds.
Custom size Quad Ring/X-Rings can require a tooling cost in some compounds.
