Water leak prevention washer

Strongly bonded with metal and rubber through vulcanization! Sizes available from M1 to M20.

In fastening, there are many cases where the flexibility and adhesion of rubber are utilized to provide sealing or cushioning functions. However, since rubber alone cannot maintain strength, backup and holding power from metal washers are necessary, which affects cost performance. The "Leak-Proof Washer" has a strong adhesive force due to the vulcanized bonding of metal and rubber, resulting in minimal rubber escape during fastening. This prevents rubber from being caught in the threaded part, maintaining high sealing performance, as well as providing various functions such as vibration resistance, loosening prevention, shock absorption, surface scratch prevention, and insulation. Additionally, in relation to this product, Azuma Screw also offers "Leak-Proof Screws (Nuts)." 【Features】 ■ Strong adhesion of metal and rubber through vulcanized bonding ■ Material: Metal part (stainless steel), rubber part (neoprene, EPDM, etc.) ■ Size: M1 to M20 *For more details, please refer to the PDF document or feel free to contact us.
