Product Data:

Brand:
  • Boss
Shape:

Straight

Ends Configuration:
  • 3in Male NPT
  • 3in GJ Wing Nut Thread
Features:
  • 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.
  • Easy to seal.
Use:
  • Boss couplings supply a convenient threaded fitting to connect two lengths of hose, or a single length to a male or female threaded outlet.
  • Use with Boss Ground Joint fittings.
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.
    • 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.
Specifications:
  • Recommended for steam service up to 450°F (232°C).
