Quad ® Rings (X-Ring) also named Four-lobes seals is one of our main products, featuring its high quality and a wide range of applications.
Four-lobed seals are electrometric seal rings.
It offers 4 contact areas for sealing instead of the 2 of the conventional standard O-ring.
The unique cross section has good sealing characteristics built in as part of its design, and because of this double seal action, less squeeze is required to keep effective seal. This reduction in squeeze means less friction and hence, improved seal life.
At pressure varies, Four-Lobed seals perform less movement from side to side.
The parting lines of Quad-Rings® (X-Ring) are not on any of contacted areas. They are installed between the lobes away from the sealing surface. The design prevents problem of leakage.
