Seal Packing is a type of seal used to seal and contain toxic liquids or gases in a system. Piston seals are often used in systems that work with high pressure, high temperature or harsh environments, because of their ability to withstand high pressure and high temperature.
Seal Packing can be made from many different types of plastic, such as: Rubber, Viton FKM, Silicone, Nitrile and others. Each type of plastic will have different heat and chemical resistance, so you should choose the type of piston seal that suits the needs and working conditions of the system.
Highlights:
Effective dust prevention: Sharp, flexible wiper blade design helps remove dust, mud, and metal chips from the cylinder rod.
Good abrasion and heat resistance: Made from PU (Polyurethane) or NBR material, ensuring high durability when working in environments with friction and pressure.
Standard design – easy to replace: Can be installed directly in the cylinder head groove, compatible with many hydraulic equipment lines.
Wide application: Used in lifting systems, construction machines, presses, and heavy industrial equipment.
