Regular Inspection: Periodically check the O-ring for signs of wear, such as abrasion on the surface, and aging, which may present as cracking, hardening, or discoloration. 2. Timely Replacement: Replace O-rings immediately if they are damaged, deformed, or show signs of aging. A defective O-ring can no longer ensure proper sealing performance.3. Exposure Avoidance: Prevent O-rings from being exposed to harsh environments for extended periods.Applications1.Automotive Industry: automotive engines, fuel systems, and transmission systems2.Industrial Machinery: hydraulic presses, pumps, and compressors3.Aerospace Field: fuel tanks and hydraulic actuators.4.Plumbing and Water Systems: faucets, valves, and pipe jointsKey ConfigurationsMaterial:NBR (Nitrile Butadiene Rubber)FKM-90 (Fluorocarbon Rubber)Standards Compliance: AS-112AS-568Precision Level:ID ±0.1 mm or ±0.004 inches for smaller sizes). The tolerance for the CSD could also have a specific allowable variation, say around ±0.05 mm or ±0.002 inches for common sizes.Application PhotosAfter Sales ServiceStandard Warranty: 12 monthsTimely Response and Technical Support: We have established a 24/7 customer service hotline.
