X-Ring Seal (Quad Ring) For Hydraulic Systems – Durable Rubber
Sealing Solution
The X-Ring Seal, also known as a Quad Ring, is a four-lobed sealing element designed for hydraulic and pneumatic systems. Compared with traditional O-rings, the unique X-shaped profile
provides better sealing performance, lower friction, and improved stability
in dynamic applications.
Our rubber X-ring seals are manufactured from high-quality elastomers such as NBR, FKM, EPDM, and Silicone, offering excellent resistance to oil, wear, and high pressure.
They are widely used in hydraulic cylinders, pumps, valves, and industrial machinery.
Key Features
- Four-lip design for enhanced sealing performance
- Reduced friction and wear compared with O-rings
- Prevents twisting or rolling during operation
- Suitable for dynamic and static sealing applications
- Available in various materials and custom sizes

| Application | - Hydraulic system - In hydraulic equipment, the X-ring is widely used in sealing of
components such as hydraulic cylinders, hydraulic pumps, and
hydraulic valves. It ensures the sealing of the hydraulic system,
prevents hydraulic oil leakage, and ensures normal operation.
- Pneumatic system - In pneumatic equipment, the X-ring can be used for sealing of
components such as cylinders and pneumatic valves. It effectively
prevents gas leakage and improves system efficiency and
reliability.
- Mechanical transmission system - In various mechanical transmission devices such as gear boxes
and reducers, the X-ring can be used for axial sealing to prevent
lubricating oil leakage and protect transmission parts.
- Other areas - X-ring is also widely used in sealing equipment in food,
medicine, chemical industry and other industries, meeting strict
sealing performance requirements across different sectors.
