About Apm Hexseal

APM Hexseal has been manufacturing an extensive line of sealing products for protecting electromechanical switches and circuit breakers since 1947. The company's product line includes UL- and CSA-recognised cap & machine screws, washers and silicone switch covers, widely used in electrical, marine and military applications. APM Hexseal washers have a moulded silicone rubber seal (with stainless-steel as backing material) and create a 360 degree sealing barrier. The company's self-sealing machine screws feature stainless-steel construction with a silicone rubber seal and ensure a tight seal regardless of the surface finish. These screws provide full metal-to-metal contact and are available in standard and metric thread sizes. Choose from a variety of APM Hexseal screws, switch boots, washers and switch shaft seals on Raptor Supplies.
