Products Description
introduce
CR V-ring seals are a kind of rubber seals for reciprocating motion. The cross-section is V-shaped, and it is seldom used alone. It is generally used in combination with a pressure ring with cloth fabric, a support ring, and several V-shaped sealing rings. The number of sealing rings depends on the sealing pressure.
advantage
CR V-ring seals are mainly used for piston rods and plungers of heavy equipment. This rubber seal provides good stability and good wear resistance, which prevents the seal ring from being squeezed into the gap, even under harsh working conditions, such as axial or radial vibration, sudden pressure, temperature changes, etc. Can provide an excellent sealing effect. Suitable for media such as hydraulic oil, water, and emulsion.
