Boss couplings are all-purpose hose couplings, universally recommended for steam hose connections. They are also widely used for air, water, fluid petroleum, chemicals and liquid petroleum gas up to 1 in ID | Boss couplings can be applied to many types of rubber, synthetic, plastic, metallic or semi-metallic hose
- The stem part that is clamped to the hose is one half of the boss ground joint connection
- The boss ground joint spud part of the coupling serves as the other half and is usually fixed to the equipment
- The two halves are connected or disconnected by rotating the wing nut on the spud, when connected they achieve both a mechanical and a pressure seal
- Easy to seal
- Boss ground joint complete couplings supply a convenient threaded fitting to connect two lengths of hose, or a single length to a male or female threaded outlet
- Leakproof seal forms when the metal head of the stem makes contact with the patented polymer seat in the boss ground joint spud
