Expect vibration damping and noise reduction effects! It demonstrates sufficient performance even when used directly on the surfaces of black steel and cast iron.
We handle "seal washers." This is a set product that incorporates a rubber packing into a metal-drawn bowl-shaped washer. The rubber packing is press-fitted onto the threaded part of the bolt, sealing the fluid at the side. The design minimizes rubber overflow even when tightened to the appropriate torque. We use SUS304, which is resistant to rust, as the standard material. 【Features】 ■ Suitable for preventing gas and liquid leakage ■ Passed pressure tests up to 200 atmospheres (20 MPa) ■ Demonstrates sufficient performance even when used directly on the surface of black steel and cast iron ■ Vibration damping and noise reduction effects ■ The metal and rubber packing do not resonate with vibrations *For more details, please refer to the PDF materials or feel free to contact us.
