1.O-Rings Key benefits - Provides a reliable seal for both static and dynamic joints to prevent leaks in hydraulic, pneumatic, and general purpose equipment. - Available in multiple materials to match media, temperature, and chemical exposure, improving service life and reliability. - Wide range of sizes and cross sections to fit common fittings and custom assemblies with accurate, repeatable tolerances. - Durable under compression and extrusion, helping maintain seal integrity through vibration, pressure cycling, and wear. - Easy to source and replace, with clear material and size guidance to minimize downtime. Product overview 1.O-Rings are engineered seals designed to create a tight, reliable barrier between mating surfaces. They are suitable for a variety of equipment including hydraulic pumps, pneumatic systems, automotive components, plumbing fittings, and industrial machinery. Material choice, size, and hardness determine performance in a given application, and the available options cover general purpose, high temperature, and chemically demanding environments. Materials and compatibility - NBR (Nitrile) offers good oil resistance and general purpose sealing for standard-temperature applications. - FKM (Viton) provides high temperature and chemical resistance for demanding media and elevated service conditions. - EPDM delivers strong resistance to water, steam, and weathering; suitable for agricultural, plumbing, and some process fluids. - Silicone is effective for wide temperature ranges and non-oil media; often used in food-grade or medical applications where allowed. - PTFE and other specialty materials are available for extreme chemical resistance and unique media compatibility. Note: The exact material, hardness, and chemical compatibility depend on the specific model and size. Refer to the product spec sheet for precise guidance. Sizes and fit - Available in a broad selection of inner diameters and cross-section sizes to match a wide range of fittings and housings. - Tolerances are maintained to ensure consistent compression and sealing performance across batches. - When selecting, use the size chart and consider operating temperature, media, and installation method to choose the correct material and hardness. Performance characteristics - Sealing performance depends on material choice, surface finish of mating parts, installation torque, and operating conditions. - Temperature and chemical resistance are material dependent; select the appropriate material for the intended media and environment. - Compression set resistance contributes to long-term seal integrity under repeated pressure cycles. - Mechanical stability helps prevent extrusion in high-pressure or dynamic sealing applications. Applications and use scenarios - Scenario 1: Hydraulic pump or valve assembly on industrial machinery Use 1.O-Rings to seal piston or rod joints where oil or hydraulic fluid is present. Choose a material with oil resistance and suitable temperature range, and select a size that matches the housing and bore with proper compression. - Scenario 2: Automotive engine or fuel system connections Use O-rings to seal connections in cooling, fuel, or air systems where media exposure and vibration are present. Material should be chosen for chemical resistance and thermal cycling, with an appropriate hardness for the joint design. - Scenario 3: Plumbing and water filtration systems Use EPDM or silicone O-rings for water-based systems and filters, where moisture exposure and potential steam or high humidity are factors. Ensure compatibility with the media and operating temperature. Installation and maintenance tips - Inspect both sealing surfaces for nicks, scratches, and debris before installation. Clean thoroughly and ensure surfaces are dry. - Use compatible lubricants only. Some materials require specific lubricants; avoid petroleum-based greases on materials not rated for them. - Do not stretch or twist O-rings during installation; fit evenly to avoid damage. - If replacing existing seals, verify that the new O-ring size and material match the original specifications to maintain performance. - Store O-rings in a clean, dry environment away from direct sunlight and ozone sources to preserve material properties. Why choose these O-Rings - Clear emphasis on material compatibility and size range to meet a variety of sealing needs. - Consistent tolerances and reliable performance across batches. - Broad material options to suit oil, water, air, chemical, and high-temperature applications. - Practical guidance to help select the right material, size, and installation approach for your specific use case. Note - For precise specifications, refer to the product data sheet that accompanies your pack or the model-specific documentation. Material grade, hardness, size range, and compatibility are defined by the exact model and should be verified before ordering.
