Ground Joint Double Spuds are used to connect hoses with female ground joint couplings together. Each side has the ground joint wing-nut thread and special polymer seal.
Streamline multiple length bull hose setups: Install female ground joint couplings on each hose end and use double spuds to connect.
-
Double spuds will not connect to NPT couplings
-
only use with ground joint female couplings (do not use if female swivel requires an external gasket)
1-1/4" and larger sizes are plated iron, smaller sizes are plated steel
3/4" & 1" use the same wing nut thread, and 1-1/4 & 1-1/2" use the same wing nut thread
