V-ring seal
An axially acting elastic rubber seal, used for pressure-free shaft sealing. The sealing lip offers good mobility and adaptability, capable of compensating for significant tolerances and angular deviations, preventing internal grease or oil from leaking out, as well as guarding against the intrusion of external splashes or dust.
O-ring
Primarily used for static seals and reciprocating motion seals. For rotational motion sealing, it is limited to low-speed rotating seal devices.
Oval Sealing Ring
Typically installed in the grooves of either the outer or inner circular sections, where they serve as a sealing function.
YX Type Bushing Retainer
Product Application: This standard is applicable when the working pressure of the hydraulic cylinder exceeds 16MPa, for use in conjunction with YX-type sealing rings, or when the cylinder is subjected to eccentric forces, serving to protect the sealing rings. Operating Temperature: -40~+100℃; Working Medium: Hydraulic oil, emulsion, water; Product Hardness: HS92±5A; Material: Polytetrafluoroethylene.

Axial YX Type Sealing Ring
Product Usage: Suitable for sealing piston rods in reciprocating hydraulic cylinders. Application Range: TPU: General hydraulic cylinders, hydraulic cylinders for general equipment. CPU: Hydraulic cylinders for construction machinery and high-temperature, high-pressure oil cylinders. Material: Polyurethane TPU, CPU, rubber. Product Hardness: HS85±2°A. Working Temperature: TPU: -40~+80℃; CPU: -40~+120℃. Working Pressure: ≤32Mpa. Working Medium: Hydraulic oil, emulsion fluid.
Y-type seal ring
Widely used in reciprocating motion sealing devices. Additionally, there are spring tension (spring stored energy) sealing rings, which incorporate a spring into PTFE sealing material. These include O-shaped, V-shaped, and U-shaped springs.
Kongyu YX-type sealing ring
Product Application: Used for sealing the piston in reciprocating hydraulic cylinders. Application Range: TPU: General hydraulic cylinders, hydraulic cylinders for general equipment. CPU: Hydraulic cylinders for construction machinery and high-temperature, high-pressure oil cylinders. Material: Polyurethane TPU, CPU, rubber products. Hardness: HS85±2°A. Working Temperature: TPU: -40~+80℃; CPU: -40~+120℃. Working Pressure: ≤32Mpa. Working Medium: Hydraulic oil, emulsion.
