The design makes it difficult for the rubber to protrude even when tightening to the proper torque! It seals the fluid at the sides.
At Sanwa Ai, 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. Designed to minimize rubber overflow even under proper torque tightening, we use SUS304, which is resistant to rust, as the standard material. The packing options available are NBR (standard specification), silicone, fluororubber, and EPDM. 【Features】 - Suitable for preventing gas and liquid leakage - Passed pressure test of 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 - Metal and rubber packing do not resonate with vibrations *For more details, please refer to the PDF materials or feel free to contact us.
