The Phillips 3/8" Female Pipe Thread Swinger Gladhand is designed to provide a secure connection between air brake systems on piggyback and intermodal trailers. This gladhand features an anodized finish for greater defense against chemicals, road salt, and magnesium chloride. The inner seal of the gladhand keeps out dust and bugs, while the long-lasting return spring is made of stainless steel. The swinger gladhand immediately returns to its sealed position when not in use, guarding the air lines. FleetPride is your First Click in Heavy Duty®.
