When you're working on machinery, plumbing, or hydraulic systems, a reliable seal can make all the difference between a job well done and a frustrating leak. These premium FKM fluorine rubber O-rings are designed for those moments when you need sealing you can count on, time after time.
What sets these O-rings apart is their FKM fluorine rubber construction. Unlike standard rubber seals, these can handle extreme temperatures (up to 200°C), resist chemicals, oils, and fuels, and won't degrade from ozone exposure or aging. The 3.1mm cross-section provides just the right amount of flexibility to create a tight seal while maintaining durability.
You'll find these 65mm diameter O-rings popping up in all sorts of places. They're ideal for automotive engine repairs, industrial machinery maintenance, hydraulic systems, and plumbing fixtures. The green color makes them easy to spot during installation, and with 5 in a pack, you'll have replacements ready for future repairs.
Getting the best performance from these O-rings starts with proper installation. Always clean the sealing surfaces thoroughly before installation, and make sure the O-ring isn't twisted or pinched. For machinery applications, consider using a small amount of compatible lubricant to help the O-ring seat properly during the first few cycles.
Whether you're a professional mechanic or a DIY enthusiast working on home repairs, these O-rings offer the protection you need. The chemical resistance means they'll stand up to brake fluid, hydraulic oil, and other automotive chemicals without swelling or deteriorating. Heat resistance ensures they maintain their sealing properties even in high-temperature environments like engines or industrial equipment.
