Boss Ground Joint Double Spud

Application

• 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” ID.
  
• Boss couplings can be applied to many types of rubber, synthetic, plastic, metallic or semi-metallic hose. Consult Dixon for specific media capabilities.
  

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
  

Specifications

• Recommended for steam service up to 450°F (232°C).
  

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.
  
• 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.
  
• Easy to seal
