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.
