Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.
High-Performance X-Ring Seals: Quad-Ring Solutions for Precision Sealing Applications
Optimized for Dynamic&Static Sealing – Reduces Friction, Extends Service Life
Our X-Ring Seals redefine precision sealing with a unique 4-lip "X" cross-section—outperforming traditional O-rings by resisting twist, reducing friction, and ensuring leak-proof reliability. Crafted from premium elastomers (NBR for oil resistance, FKM for high temperatures, EPDM for weather durability), they excel in environments ranging from -60℃ to 260℃, fitting hydraulic/pneumatic systems, automotive parts, and food/medical equipment.
Precision-molded for consistent 4-lip symmetry and post-cured to minimize compression set, these seals extend service life while meeting strict industry standards. Ideal for both dynamic (reciprocal motion) and static applications, they deliver cost-saving value by cutting maintenance needs—your trusted choice for durable, high-efficiency sealing.

1. Product Advantages
Superior Sealing Performance: Unlike traditional O-rings, our X-Ring features a 4-lip "X" cross-section that creates dual sealing points, eliminating leak risks even in high-pressure (up to 50MPa) dynamic or static applications.
Exceptional Durability: Made with lab-tested elastomers (NBR, FKM, EPDM, PU), our seals resist twist, wear, and compression set (≤20% after 72h at 120℃). They outlast standard seals by 30% in industrial use.
Wide Temperature Adaptability: Engineered to perform from -60℃ (VMQ grade for low temps) to 260℃ (high-performance FKM grade), suitable for extreme environments like automotive engines or cryogenic systems.
Cost-Efficiency: Reduced friction lowers equipment energy consumption; longer service life cuts maintenance frequency and replacement costs for your operations.
2. Working Principle
Forever’s X-Ring Seals rely on two core mechanisms:
4-Lip Pressure Distribution: When installed in a groove, the X-shaped cross-section’s four lips evenly distribute contact pressure with the mating surface. This prevents localized wear and ensures consistent sealing, even if the equipment vibrates or shifts.
Elastomer Elastic Recovery: Our premium elastomers (e.g., FKM, EPDM) retain elasticity under pressure or temperature changes. When compressed, they “bounce back” to fill gaps, blocking fluids, gases, or contaminants from leaking.
3. Product Details
Material Options: Customizable based on your needs—NBR (oil-resistant for hydraulics), FKM (chemical-resistant for aerospace), EPDM (weatherproof for outdoor use), and food-grade VMQ (for medical/food machinery).
Dimensional Accuracy: Precision-molded with CNC tools, ensuring inner diameter (ID) 0.5mm–200mm, outer diameter (OD) 1.5mm–202mm, and cross-section (CS) 0.5mm–10mm. Tolerance ≤±0.05mm for tight fits.
Surface Finish: Smooth, burr-free surface (Ra ≤0.8μm) after cryogenic deburring, reducing friction and preventing fluid buildup.
Certifications: Compliant with ISO 9001, RoHS, and FDA (for food/medical grades), meeting global industry standards.
4. Application Range
Forever’s X-Ring Seals are trusted across industries:
Automotive: Hydraulic brake systems, transmission seals, engine oil caps.
Industrial Machinery: Hydraulic cylinders, pneumatic valves，machine tools coolant seals.
Aerospace & Defense: Aircraft fuel lines, rocket engine high-temperature seals.
Food & Medical: Food processing equipment (e.g., dairy pumps), medical device fluid paths (FDA-grade VMQ).
Marine: Ship hydraulic steering systems, underwater equipment (corrosion-resistant FKM).
5. FAQ (Frequently Asked Questions)
Q1: How do I choose the right material for my application?
A: Contact our engineering team with details (fluid type, temperature range, pressure), and we’ll recommend the optimal elastomer (e.g., NBR for mineral oil, FKM for acids).
Q2: Can Forever Seals customize X-Rings for non-standard sizes?
A: Yes—we offer custom molding for unique ID/OD/CS dimensions, with a minimum order quantity (MOQ) of 50 pieces for most materials.
Q3: What is the shelf life of your X-Ring Seals?
A: 2–5 years (depending on material) when stored in a cool, dry place (15–25℃, away from direct sunlight and ozone).
