SWS is a stainless steel sealing washer with a built-in rubber seal. Washers prevent the leakage of gas and liquid from the bearing surface of the screw head. Test results for JIS C 0920 protection degree IPX7 are available on our website. The rubber does not escape even when the screw is tightened, and the rubber contacts tightly with the thread peak section to form a seal. Fluororubber is used for rubber seal of SWS-F, which has excellent chemical resistance, heat resistance, and ozone resistance.
