1. Product Advantages
Crafted from high-grade PEEK material, our Beige Back Up Rings deliver standout performance for industrial sealing needs. They boast superior thermal stability—withstanding 260°C for long-term continuous use and up to 300°C for short intervals—making them reliable in high-heat environments like engine bays or chemical reactors. With strong chemical inertness, they resist corrosion from common solvents, acids, and alkalis, avoiding seal degradation even in aggressive fluid-handling systems.
The natural beige hue isn’t just aesthetic: it enables quick authenticity checks, helping teams distinguish genuine PEEK rings from lower-quality alternatives during inventory or maintenance. Plus, their high mechanical strength (100MPa+ tensile strength) and low friction coefficient (0.05–0.15) reduce wear and deformation, extending service life by 2–3 times compared to standard back-up rings. This longevity directly cuts down on replacement frequency and maintenance costs for your operations.
2. Working Principle
Designed to solve the common issue of primary seal extrusion in high-pressure systems, these Beige PEEK Back Up Rings act as a critical support. When primary seals (such as O-rings or gaskets) face pressure-induced squeezing, the rings fill the gaps between mating parts, creating a rigid barrier. This prevents the primary seal from displacing or getting damaged.
By distributing pressure evenly across the entire sealing interface, they maintain a tight, consistent seal—even when pressure fluctuates, like in hydraulic cylinders or fuel lines. They work seamlessly in both static (fixed components) and dynamic (moving parts) setups, ensuring no leaks and protecting expensive equipment from premature wear or failure.
3. Product Details
Material: Made of 100% virgin high-grade PEEK (Polyether Ether Ketone), free from fillers or additives. It meets RoHS and REACH environmental standards, making it safe for diverse industrial applications.
Color: Natural beige, a characteristic of pure PEEK (no artificial dyes). This color aids in material traceability, a key requirement for industries like aerospace and pharmaceuticals.
Precision: Machined using advanced CNC technology with a tight tolerance of ±0.02mm. This ensures a perfect fit for both standard sealing grooves (e.g., AS568, ISO 3601) and custom-designed grooves (available on request).
Quality Assurance: Each production batch undergoes strict testing—including thermal stability checks (exposed to 260°C for 1000 hours), chemical resistance tests (immersed in 10+ industrial fluids), and dimensional inspections via laser tools—to guarantee consistency and reliability.
Packaging: Tailored to application needs: electronics-grade rings come in anti-static film to protect against static damage, while industrial-use rings are packed in moisture-proof containers. All packaging includes clear labeling with product code, size, batch number, and manufacturing date for full traceability.
4. Application Range
These Beige PEEK Back Up Rings are versatile enough to meet the demands of multiple key industries:
Automotive & EV: Ideal for transmission systems (sealing gear oil), battery cooling circuits (resisting glycol-based coolants), and fuel lines (withstanding ethanol blends). They work for both internal combustion engine (ICE) vehicles and electric vehicles, where high-temperature resistance is crucial.
Aerospace: Used in aircraft hydraulic systems, which face extreme altitude pressure changes. They comply with aerospace standards like AMS 7244, ensuring reliability in critical flight components.
Chemical Processing: Installed in reactor flanges, pump shafts, and valve stems. They handle corrosive media, making them suitable for pharmaceutical, petrochemical, and food processing plants (where hygiene and chemical resistance are non-negotiable).
Oil & Gas: Applied in wellhead equipment (sealing crude oil and natural gas under high pressure) and offshore pipelines (resisting saltwater corrosion). They meet API 6A standards, a benchmark for oilfield equipment safety.
Electronics: Integrated into semiconductor manufacturing equipment (sealing vacuum chambers) and LED cooling systems (tolerating thermal cycling). Their excellent electrical insulation (volume resistivity of 10¹⁶ Ω·cm) protects sensitive components.
5. FAQ
Q: Are these Beige PEEK Back Up Rings compatible with the O-rings I already use (e.g., Viton, EPDM)?
A: Yes—they’re designed to work seamlessly with all common primary seal materials, including Viton, EPDM, nitrile, and PTFE. Their smooth surface prevents abrasion on the primary seal, while their rigid structure provides reliable support even for softer O-rings in high-pressure setups.
Q: Can I order custom sizes for non-standard sealing grooves in my equipment?
A: Absolutely. Just share your groove dimensions (inner diameter, outer diameter, thickness), along with your application’s temperature and pressure requirements, and our engineering team will design a tailored solution. Custom orders have a lead time of 5–7 business days, with prototypes available for testing if needed.
Q: How should I store these rings to keep them in good condition?
A: Store them in a cool, dry environment with temperatures between 15–25°C and relative humidity below 60%. Avoid direct sunlight, oils, and chemicals, and don’t bend or compress the rings (PEEK retains shape but can suffer permanent damage from excessive force). When stored properly, they have a shelf life of 5+ years.
Q: Do you provide any certifications to verify the quality of these rings?
A: Yes. We offer material certificates (confirming PEEK grade), RoHS/REACH compliance certificates, and performance test reports (thermal resistance, chemical resistance) upon request. For industries like aerospace or medical, we can also provide additional certifications such as ISO 9001 or AS9100 to meet strict regulatory requirements.
