Unique features to handle the most complex sealing
Download Trelleborg’s Quad-Rings® Technical Resource Sheet.
- 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.
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.
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.
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.
