A set of two turned pin fittings with a brass-coloured finish, each built around a hexagonal body section. These connector parts are precision components engineered to link systems, compatible with small, medium and manifold assemblies. The smaller fitting has a hex section, a slotted body and a pointed fluted pin at one end. The larger fitting has a hex end, a threaded section, a flange with a cut slot and a long fluted shaft. Both are manufactured to meet exact tolerances and material specifications for reliable performance.
