The four-lip seal , also known as a Quad-Ring or X-Ring, is a sealing element designed with an X-shaped cross-section that incorporates four sealing surfaces. Its geometry improves sealing and reduces friction compared to conventional O-rings.
It features four support points that provide greater resistance to extrusion and pressure. This seal also stands out for the flexibility of its lips, which reduces friction and wear. Regardless of the direction of the force (radial or axial) , it ensures an optimal seal, even under low pressure conditions.
Its main function is to prevent fluid or gas leaks in static and dynamic systems. It is used to maintain a tight seal in cylinders, valves, shafts, pistons, and various industrial components.
The 4-lip gaskets offer:
Quad-Ring gaskets are used in:
The O-ring has a circular cross-section, while the 4-lip seal features an X-shaped geometry. This configuration allows for more contact points and improves sealing stability.
Yes. Four-lip seals are widely used in hydraulics due to their ability to withstand pressure and maintain a reliable seal for extended periods of operation.
To do this, it is necessary to know the inner diameter, the outer diameter, the joint section, and the dimensions of the housing.
The correct selection ensures the watertightness and performance of the system.
