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
