Inch Size Nitrile Rubber Quad Rings Seals Professional High Stability

The sealing principle of the Quad™- ring is nearly the same as the O-ring sealing. The initial sealing is achieved by the diametrical squeeze in a right angled groove. The system pressure
itself creates a positive sealing force.Following are some advantages of Quad™-rings:- With Quad™-rings the standard grooves are deeper in comparison with O-ring glands. So diametrical
squeeze is lower than with O-rings. This makes dynamic sealing possible with reduced friction.


- The four lips of the Quad™-ring create more sealing capacity and at the same time a groove for lubrication,which is very favorable for dynamic sealing.
-The most important advantage of the Quad™-ring is the high stability for dynamic applications. In the situation that an O-ring rolls in the groove and creates torsion, a Quad™-ring will slide with no
negative results.
- More resistant to spiral failure.
Note 1:
It is recommended, especially for dynamic seals, to use the Quad™-ring with the largest possible cross section or thickness because thicker rings can withstand more tolerance variance.A 4-inch I.D. (100 mm) Quad™-ring is available with cross sections of .070(1,78 mm), .103 (2,62 mm), .139 (3,53mm), and .210 (5,33 mm). For dynamicapplications use, if there is room, the largest cross section available (.210 /5,33 mm).
Note 2:
Because Quad™-ring glands have deeper grooves than O-rings,standard O-ring back-up rings cannot be used. The actual groove dimensions are needed to supply the correct sized machined back-up ring.
Note 3:
Use FKM Quad™-rings with minimum stretch because FKM Quad™-rings have a smaller tolerance range than NBR Quad™-rings.Standard cross sections of Quad™-rings
Application Range from vacuum to 6000 psi (400 bar, 40 MPa.). Over 750 psi (50 bar, 5 MPa.) when used inconnection with back-up-rings. Speeds up to 1.6 ft/s (0.5 m/sec.)reciprocating).
Surface finish is the same as with Oring applications. See page 15 and 24.The temperature range is from -50°C .
