The Watts IWTG Manifold Pressure Test Kit is an excellent
inexpensive solution for aire pressure testing a piping system from a hose
drain fitting. The Kit has a 100 psi pressure gauge mounted on a
chrome-plated brass manifold. It has a ¾” Female NPT fitting at one end
for connection to your piping system and a 1/8" Schrader type air valve
at the other for easy filling from an air chuck. You will need the
included MPT x FHT adapter to connect the IWTG to the hose drain fitting
on the manifold.
Watts Regulator brand Series IWTG-Gas Air Test Assembly Gauges are
used in commercial, residential, and institutional HVAC applications.
