Piston Seals B7 is the piston seal for heavy-duty travel machinery
B7 piston seal is a lip surface seal for tight fitting installation in the groove. The seal can be used for various occasions where the physical properties of ordinary rubber or fabric reinforced rubber cannot meet the requirements.
B7 series U ring is a single acting piston seal made of polyurethane rubber injection forming. It has a strong dynamic seal lip and a large contact area of the static seal lip to ensure the effective positioning of the U-ring in the groove.
The section of the seal ring is suitable for pressures up to 40 MPa, providing an extrusion clearance to match the pressure value.
Due to the good elasticity of polyurethane rubber material, u-rings can be easily installed in enclosed grooves.
