Viton O‑Ring — 338.6 mm (ID) x 350 mm (OD) x 5.7 mm (wire diameter) Key benefits Reliable sealing for cylindrical overlapping surfaces: round crosssection creates a tight seal between mating cylindrical parts to prevent leaks. Flexible and conforming: soft, elastic material adapts to irregular or complex component shapes for consistent contact and improved sealing performance. Durable material: made from Viton (fluoroelastomer), formulated for demanding sealing applications where resistance to oils, fuels, and many chemicals is required. Precise fit: specified dimensions (338.6 mm ID × 350 mm OD × 5.7 mm wire diameter) match assemblies that use this exact O‑ring size, enabling straightforward replacement. What this solves Prevents fluid and gas leaks at cylindrical joints and overlaps, reducing downtime and maintenance. Maintains seal integrity under repeated compression and motion thanks to elasticity and resilience. Offers material compatibility for systems exposed to hydrocarbons and many industrial fluids, reducing premature failure from swelling or degradation. Compatibility and performance Material: Viton (FKM) elastomer suitable for a wide range of demanding sealing tasks. Function: designed specifically to seal between cylindrical overlapping surfaces; retains elasticity to maintain contact under load. Size: confirm the 338.6 mm ID, 350 mm OD, and 5.7 mm wire diameter match your application before ordering. Typical applications Automotive and engine systems: valve covers, housings, or other cylindrical joints exposed to oils and fuels. Hydraulic and pneumatic cylinders: rod, piston, or endcap seals where a resilient, chemicalresistant O‑ring is needed. Industrial pumps and compressors: seals in fluidhandling equipment and machinery requiring leaktight cylindrical interfaces. Installation tips Verify dimensions against the groove and mating parts before installation. Use a compatible lubricant during installation to ease fitting and avoid twisting the O‑ring. Inspect for cuts or nicks before assembly to ensure a reliable seal.
