PURPOSE: To supply a convenient threaded fitting needed to connect two lengths of hose, or a single length to a male or female threaded (NPT) outlet on any type of equipment.

The Spud part of the coupling serves as one half of the connection and is usually fixed permanently to the equipment. The Stem and Nut attached (clamped) to the hose is the other half. The two halves are connected or disconnected by rotating the Wing Nut on the Spud, to achieve a mechanical as well as a pressure seal.

SERVICES: All-Purpose Hose Couplings, universally recommended for steam hose connections. They are also widely used with equal efficiency for high or low pressure Air, Water, Liquid Petroleum Gas, Fluid Petroleum Products, Chemicals, Potable Fluids and almost any other type of fluid or gas.* They can be applied to all types of rubber, synthetic, plastic, metallic (with special stems) or semi-metallic hose. * Consult Factory for specific media capabilities.

Ground Joints
The leakproof seal in the "Boss" Coupling is affected in the Ground Joint Style by a soft-to-hard-polymer connection when the rounded head of the steam is in firm contact with the beveled polymer insert in the Spud. Job down time to replace lost or deteriorated washers is eliminated and the sealing efficiency is not affected by dirt, grime or by normal wear through repeated use.
