What's in the box:
GMC Hose to NPTM Adapter, Brass
This Brass Hose to NPTM Adapter Converts a Hose with a 1/4" Female Swivel Cap to 1/4" Male NPT. Pneumatic Hose Systems often use End-Fittings consisting of a Swiveling Compression Cap (JIC) which mates to a Dome-Shaped Pipe Fitting, thereby Adapting Hose to 1/4" NPT. Swivel Caps allow the Hose to be Properly-Aligned before the Cap is Tightened-to-Form an Air-Tight Joint. Adapter has a 3000 psi (200 bar) Service Pressure.
