FKM (VITON) O-RING SEALS – 70 SHORE A
OIL & FUEL RESISTANT • HIGH TEMPERATURE SEALING
In real-world operation, a tiny O-ring that hardens or starts leaking can lead to a chain of problems: oil stains on equipment, pressure loss, fuel wastage, and unplanned downtime. That’s why for systems exposed to oils/fuels and higher temperatures, FKM (Viton) O-rings are often the go-to choice for longer service life and more reliable sealing.
These 70 Shore A FKM O-rings are manufactured by Anh Trí Tuệ and stocked for ongoing supply for maintenance, replacement, and new installations.
- KEY ADVANTAGES OF 70 SHORE A FKM O-RINGS
- Excellent resistance to oils, grease, and fuels: ideal for hydraulic oil, lubricating oil, gasoline/diesel applications.
- High heat resistance, less hardening over time: helps maintain elasticity and consistent sealing in hot environments.
- Good aging resistance: performs well in continuous operation, vibration, and harsh conditions.
- Versatile 70 Shore A hardness: easy to install, strong sealing performance, compatible with many standard grooves; suitable for static sealing and light dynamic applications.
- Reduced leakage and downtime: longer O-ring life means fewer replacements and lower maintenance costs.
- COMMON REAL-WORLD APPLICATIONS
FKM O-rings are widely used in many everyday sealing points, such as:
- Oil and fuel systems: pump covers, filter housings, pipe connectors, covers, flanges.
- Hydraulic equipment: fittings, manifolds, oil distribution blocks, valve covers, hot oil sealing points.
- Industrial valves and piping accessories: sealing for valve bodies, caps, stems (depending on design), and connections.
- Industrial machinery: compressors, generators, engines, and other equipment operating in hot, oil-exposed areas.
- Plant maintenance (MRO): quick replacement for O-rings that tend to leak due to heat and oil/fuel exposure.
- WHEN IT MAKES SENSE TO UPGRADE TO FKM
FKM is a practical option if you’re dealing with:
- O-rings that harden, crack, or fail quickly when equipment runs hot
- Oil leakage or fuel smell/penetration after a short time in service
- Continuous-duty equipment where frequent shutdowns are not acceptable
- The need for stable sealing to hold pressure and reduce losses
- STOCK SIZES + CUSTOM PRODUCTION
- Available in common sizes from stock for fast replacement needs.
- Custom manufacturing to required dimensions (ID x CS), based on old samples or groove drawings.
- Material selection support based on media, temperature, and sealing conditions to minimize mismatch risk.
- QUICK NOTE FOR PROPER SELECTION
FKM performs very well with oils/fuels and high temperatures. For some special media (for example hot steam or certain strong solvents), please share the details so we can confirm compatibility and recommend the most suitable option.
- WHAT TO SEND FOR FAST QUOTATION
Just send:
- O-ring size (ID x CS) or a photo of the old O-ring with a ruler
- Working media (which oil/fuel/chemical)
- Working temperature (typical and max if available)
- Static sealing or any movement (sliding/rotating)
70 Shore A FKM (Viton) O-rings are a reliable choice for sealing in oil/fuel systems and high-temperature environments. If you’re looking to reduce leaks and extend maintenance intervals, this is a smart upgrade.
Message us your size + media + temperature, and Anh Trí Tuệ will advise the right option and provide a quick quote—either from stock sizes or made-to-order.
