Quad Ring (X-Ring) Seals
Quad ring, commonly named X-ring, is a premium four-lip rubber sealing component upgraded from traditional O-rings. As a professional manufacturer ofcustom quad ring seals, we produce high-precision moulded rubber quad rings designed for static and dynamic sealing scenarios, solving common leakage, friction and wear problems of standard sealing rings.
All our moulded quad ring products are crafted from premium industrial rubber materials including NBR, EPDM, silicone and neoprene. Featuring a unique four-lip symmetrical structure, these quad ring seals deliver double sealing performance, lower friction coefficient and longer service life compared with conventional O-rings, ensuring stable and leak-free operation in complex industrial environments.
Professional Quad Ring Moulding Process
We adopt precise compression and injection moulding technology to manufacture consistent, high-quality rubber quad ring seals, supporting standard specifications and fully customized production:
Precision Moulded Quad Ring Production
Every custom quad ring is produced with precision custom moulds to ensure accurate groove matching, uniform lip height and smooth surface finish. Strict dimensional tolerance control eliminates deformation and sealing failure caused by size deviation. Mass-produced quad rings maintain perfect batch consistency, suitable for long-term large-scale industrial matching.
Core Advantages of Our Rubber Quad Ring Seals
-
Superior Double Sealing Performance: The unique four-lip symmetrical structure provides dual sealing protection, effectively preventing liquid and gas leakage under high pressure and vacuum conditions.
-
Low Friction & No Twisting: Different from O-rings, quad ring seals avoid rolling and twisting during reciprocating and rotating movements, reducing friction loss and extending component service life.
-
Excellent Environmental Resistance: Our moulded quad rings feature outstanding oil resistance, heat resistance, aging resistance and chemical stability, adapting to high-temperature, low-temperature, oily and corrosive working conditions.
-
Full Customization Support: Custom quad ring size, hardness, material and color according to customer drawings, samples and application requirements to meet non-standard sealing needs.
-
Reliable OEM & ODM Service: One-stop solution from mould design, prototype testing and trial production to mass delivery, supporting global industrial customization orders.
Wide Applications of Quad Ring Seals
Our durable custom quad ring seals are widely used for static and dynamic sealing in various industrial equipment, ideal for scenarios requiring high precision and zero leakage:
-
Hydraulic & Pneumatic Systems: Cylinder sealing, valve body sealing, pipeline connection seals for hydraulic and pneumatic equipment
-
Automotive Industry: Engine oil circuit seals, brake system seals, chassis hydraulic component quad rings
-
Mechanical Equipment: Precision machinery rotating shafts, reciprocating parts, anti-leakage sealing components
-
General Industrial Hardware: Vacuum equipment, water treatment facilities and pipeline sealing systems
FAQ for Custom Quad Ring Seals
What is a quad ring seal used for?
A quad ring (X-ring) is a four-lip rubber sealing part used for static and dynamic sealing. It is mainly applied in hydraulic, pneumatic, automotive and mechanical systems to prevent fluid and gas leakage, with better stability than traditional O-rings.
Are quad rings better than O-rings?
Yes. Custom quad ring seals adopt a symmetrical four-lip structure, featuring lower friction, anti-twist performance and double sealing effect. They are more durable and stable than O-rings in high-pressure and frequent movement scenarios.
Can you produce custom size quad rings?
Absolutely. We provide full customization for all rubber quad ring products. We can develop exclusive moulds and produce non-standard quad rings according to your design drawings, sample sizes and performance requirements.
