O-Rings
O-rings are annular rubber packings used for pumps, hoses, gaskets, tank linings, diaphragms, etc. Used to prevent fluids such as water, oil, gas, chemicals, etc. flowing through machines such as pumps and hoses from leaking outside. Most of them are made of nitrile rubber or synthetic rubber, and there are two types for S-type fixation and P-type exercise. In addition, some products have different hardness and heat-resistant temperature, and some have excellent oil resistance, wear resistance, and aging resistance.
