Benefits of Quad® Brand Seals
- Twice the sealing surface: Quad-Ring® Brand Seals have a unique four-lobe design to provide two sealing surfaces, offering greater protection as an ID, OD, or face seal.
- Lower friction: Less squeeze is required to maintain a seal with the Quad-Ring® Brand Seals, meaning less friction, which is important in dynamic applications.
- Extrusion resistance: Unique cross-section of the seal resists spiral twisting that can cause conventional O-rings to rupture.
- Reduced leakage: Where O-rings have parting lines on the sealing surface, these lines lie between the lobes in Quad-Ring® Brand Seals, eliminating leakage problems.
- Longer life: Reduced squeeze also extends the seal longevity and requires less maintenance.
- Versatile: Available in the same standard sizes as O-rings, Quad-Ring® Brand Seals have proven successful in a variety of seal applications.
