21/2 FNST X 2 MNPT PIN LUG BRASS HYDRANT

Description & Features

Designed for hydrant and fire hose connection applications, this brass adapter from Dixon Valve & Co. provides a reliable transition between a 2½-inch female national standard thread (NST) inlet and a 2-inch male NPT outlet. The pin lug configuration allows for quick coupling and uncoupling using a spanner wrench, making it well suited for use on hydrant outlets, standpipe systems, and similar municipal or industrial water distribution access points.

Constructed in brass, the 21/2 FNST X 2 MNPT Pin Lug Brass Hydrant adapter offers corrosion resistance appropriate for wet service environments. The NST thread pattern conforms to standard fire hose coupling dimensions, while the male NPT end allows straightforward connection to threaded fittings and valves.

Is this hydrant adapter made of brass all the way through? Just want to make sure it'll hold up to some weather.

it's constructed entirely from brass, which gives it good corrosion resistance, especially when it's exposed to wet conditions.
