It’s an easy one-piece solution that you don’t have to piece meal together from three or four pieces; simply connect the valve and you’re ready to go. The kits include a compact duffel bag, 2.5” (64 mm) standpipe valve with pressure gauge, (2) spanner wrenches, a 2.5”x1.5” reducer for use with a 1.5” coupled hose off the valve, and a 1.5”x 2.5” increaser for break and extend hose operations off of a ball shutoff valve.
