Quad Ring Composed of 4 Lobes, Great Resistance of Abrasion, Lower Coefficient Of Friction, Keeps the Pressure Even, More Efficient

Quad-Ring® Brand Seal Advantages over standard O-Rings:

Twice the Sealing Surface. Quad-Ring Brand seals have a unique multiple point seal contact design. With two sealing surfaces, there is greater seal protection when used as an ID seal, OD seal, or face seal.
Lower Friction because of the Quad-Ring® Brand seals' multiple point seal contact design, less squeeze is required to maintain an effective seal. This lower squeeze results in lower friction, an important consideration for dynamic sealing applications.
Longer life because of reduced squeeze. Quad-Ring® Brand seals last longer and promote system "uptime." Equipment operates longer and requires less maintenance.
Seal surface free from parting line insures no leakage across the parting line. Parting line is in the valley not on the sealing surface like conventional O-Rings.
No spiral twist. Four lobe shaped Quad-Ring® Brand seals eliminate spiral twist which causes conventional O-Rings to rupture.
For sealing across a broader tolerance range, the Modified Quad-Ring® Brand seal has a deeper valley than the original Quad-Ring Brand seal design, thereby producing a lower deflection force. In OEM applications such as plastic housings, this seal design has reduced load with less creep. Designed for pressures less than 120 psi (8.1 bar). Modified Quad-Ring Brand seals recently were granted a new patent.
For dynamic sealing applications providing near zero leakage at pressures to 2000 psi (138 bar) and higher. This six-lobed configuration, designed with two primary and four backup sealing surfaces, has excellent sealing features in very difficult applications. It can be used with standard O-Ring grooves.
