Flat sealing gaskets are made of PTFE (Polytetrafluoroethylene), which has chemical resistance, high temperature resistance, low friction, anti-stickiness, corrosion resistance, corrosion resistance, and non-conductive properties, making them very suitable for sealing corrosive fluids, gases and extreme temperature environments. 2. PTFE washers show good sealing capabilities to various oil, water, air, effectively resisting the penetration of liquids or gases, and can also be used for cushioning, reducing pressure and friction, increasing the contact area and providing a support surface for fasteners. Instruction Before installing the gasket, make sure the surface is clean and dry, place the seal gasket on the intended area that needs sealing or cushioning, and tighten the fasteners firmly to compress the gasket to achieve a tight seal or effective cushioning NOTE: Please confirm the washer diameter before ordering, and pay attention to regular inspection and maintenance of sealing gaskets
