Marshall Excelsior Serviceman's Friend Test Fitting | 5/16-32 x 1/8 MNPT x 1/2 MNPT

The Serviceman's Friend from Marshall Excelsior combines three common LP fitting sizes into one brass test tool, letting techs check line pressure on an appliance without hauling around extra bushings and fittings.

• Combines 5/16"-32 male, 1/8 in MNPT, and 1/2 in MNPT connections in one fitting
• Hose barb on one end, 1/8 in MNPT on the other
• Attach a hose to either end and connect to a manometer or flow meter to check appliance line pressure
• Solid brass construction

A handy one-piece substitute for carrying multiple individual LP test fittings on a service call.
