Reliable low-pressure and high-pressure sealing with high and low temperature resistance. Made of -resistant materials, strong and durable, long service life. Suitable for automobile maintenance, electrical appliances, faucets, cylinders, valves, pumps, automobiles, bearings, and other fields. When fully secured, the edge of the opening bites into the nut and the surface of the material to provide spring tension and increase friction. Use scenarios - Automotive maintenance: seal connections in cylinders, valves, and pumps to prevent leaks under varying pressures and temperatures. - Household and appliances: apply to faucets and valve assemblies in electrical appliances or water systems to improve sealing and reduce leaks. - Industrial equipment: use in motors, bearings, and hydraulic or pneumatic systems where reliable sealing and friction are required to maintain system integrity.
