Boss™ couplings are all-purpose hose couplings, universally recommended for steam hose connections
Boss™ couplings can be applied to many-types of rubber, synthetic, plastic, metallic or semi-metallic hose
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
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
Leak-proof seal forms when the metal head of the stem makes contact with the patented polymer seat in the Boss™ ground joint spud
Easy-to-seal
Safety Notes: Worn-out hose couplings can be dangerous.
They should be checked regularly and replace when necessary.
Each coupling user should review applications and add safety devices where indicated.
Pressurized steam is an extremely dangerous commodity.
Only hose, fittings, clamps and accessory items that have been approved for steam service should ever be used!
Never use an unapproved item for steam service.
Always follow the manufacturer's product recommendations for pressurized steam handling.
