 High Quality Black NBR FKM Rubber Quad-Ring for Machinery Seal

 

 

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.

Black NBR FKM Rubber Quad Ring For Machinery Seal 0

Black NBR FKM Rubber Quad Ring For Machinery Seal 1

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.

 

Advantages of Quad-Ring:

 

Quad-Ring has four definitive sealing advantages over an O-Ring.

Hidden parting lines, or flash lines. The flash lines (a line of excess material where the compression mold tool comes together) on an O-ring is always on the outer most diameter, which consequently is a sealing surface. On a Quad-Ring™, that flash line is on the inside of the two outer lobes; therefore, it does not effect the sealing lips.

The Quad-Ring is more stable in dynamic applications. It is also more resistant to rolling as it has a wider footprint and takes up the corners of the hardware groove. Spiral failure is common in dynamic O-ring applications in which torsion occurs and the ring can extrude or over-yield.

The Quad-Ring has great lubrication retention. The grooves on the inside and outside diameter of the ring retain lubricant, thereby lowering friction and extending packing/seal life.

Less compression force to seal. The multi-lobed design provides more sealing surfaces than an O-ring, all while using the same hardware (Quad-Rings™ are intended to be used in standard O-ring grooves). With these multiple seal points on one ring, less squeeze is required to provide an effective seal. Less friction and wear will ultimately increase service life and reduce downtime.
