Gas pressure test kit 0-10 In WC

The Yellow Jacket 78055 is an electronic gas pressure test kit designed for HVAC technicians and plumbers who need to verify low-pressure gas lines. It measures pressure from 0 to 10 inches of water column with a 36-inch slack tube for flexible positioning during testing.

Simple connection with included barb fitting

Installation requires attaching the supplied barb fitting to the 1/4-inch inside diameter hose and connecting to the test port. The electronic design eliminates fluid handling, but the kit is limited to a maximum vacuum of 1 inch Hg and a working temperature of 120 degrees F, so it must not be used on high-vacuum or high-heat applications.

Verify pressure range and temperature limits

Before ordering, confirm that the system under test operates within the 0 to 10 In WC range and that ambient temperatures will not exceed 120 degrees F. The 36-inch tube length should reach your test ports, and the 1/4-inch hose must match your existing fittings or adapters.
