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 spud part of the coupling serves as one half of the connection and is usually fixed to the equipment
• The stem part that is clamped to the hose is the other half
• 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
• Positive metal-to-polymer seal
• Leakproof seal forms when the metal head of the stem makes contact with the patented polymer seat in the spud
• The non-metallic polymer seat resists most chemicals found in manufacturing facilities, reference the corrosion resistance chart for additional information
• Boss couplings supply a convenient threaded fitting to connect two lengths of hose, or a single length to a male or female threaded outlet
• Easy to seal
• 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
• 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
• Note: 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
• Warning: this product contains a chemical known to the state of California to cause birth defects or other reproductive harm
• Do not use in connection with drinking water
• Wash hands after handling
