| ▪ 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 |
| ▪ The spud part of the coupling serves as one half of the boss ground joint 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 |
