Quad-Rings®

Unique features to handle the most complex sealing

The Quad-Ring® Seal is a four-lobed seal known as the solution for complicated applications where better performance is critical. The four contoured lobes give a Quad-Ring® twice the number of sealing surfaces as an O-Ring. The relatively square cross-section also eliminates spiral twist which is a common cause of O-Ring failure. Quad-Rings® are also an alternative product for dynamic seals in low-pressure applications.

Benefits:

  • Longer seal life.
  • Lower failure rate than other sealing solutions.
  • Reduced friction.
  • Eliminates leakage with sealing surfaces placed strategically away from parting lines.
  • Quad® Brand Seals are US-Engineered and globally manufactured, eliminating supply chain challenges.
  • Reliable and engineer trusted for critical-toperform applications.
The proprietary geometry of the Quad-Ring® leads to better performance of the seal in the application.

Applications


Reciprocating

Quad-Rings® form a positive, dependable seal at a wide range of pressures. With proper installation, they form a positive seal at a wide range of pressures from extreme vacuum up to 725 psi/5MPa without back-up rings and up to 4350 psi/30MPa with back-up rings.

Rotary

Quad-Rings® make excellent rotary seals because the low cross-sectional squeeze permits higher rotary speeds with less friction, giving longer life. The use of Quad-Rings® in these applications eliminates the need for more expensive spring-loaded seals.

Static

When Quad-Rings® are used as gaskets, they efficiently seal mating components. The four contoured lobes effectively prevent bypass in devices using frequent pressure cycles.
