Seal washer

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.

We would like to introduce our original metal product, the "Seal Washer." It excels in oil resistance, heat resistance, and weather resistance, preventing the ingress of water, oil, and air when the screw is tightened, thanks to the rubber's tight fit. We particularly recommend the thick body for outdoor use. 【Features】 ○ Can be used with various screw shapes (except for flat screws) ○ Excellent oil resistance, heat resistance, and weather resistance ○ Can be used even with large countersinks due to its wide seating surface (refer to the size chart) ○ The rubber tightly adheres when the screw is tightened, preventing the ingress of gases and liquids (the tightening torque depends on the strength classification of each size) ○ Can be reused repeatedly as long as there is no damage to the rubber ○ Especially recommended for outdoor use is the thick body For more details, please contact us or download the catalog.
