Pressure Test Kit with Extra Valve to Zero Gauge

Pressure test kit for use with TwistSeal (55 mm), TwistSeal Mini (40 mm), and Stainless Steel manifolds. Valve allows for the gauge to be "zeroed" and demonstrate that the system is under pressure. Replaces automatic air vent on cross tee (TwistSeal) or hosebib (Stainless Steel) for testing purposes. Kit includes two 1" plugs and 4 red rubber gaskets (2 are spares). For air tests use the red rubber gaskets; for hydrostatic tests use green fibre gaskets (included in manifold assembly kits).
