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
-
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
