Abstract
A pressure test gauge is described, more particularly for testing the air pressure at the outlet of a spray gun. The pressure test gauge comprises a body having an inlet which may take the form of a replaceable screw-in-unit sealed airtight with the body. The unit encircles the inlet and connects with passages passing through body. The passage is a small bore tube which connects the inlet with a pressure gauge which has a display. Intermediate the inlet unit and gauge is a valve comprising a barrel with an outer screw-thread screwed into the body. Extending axially of the valve is a metering hole. The gauge body may have ribs for facilitate gripping the body and a bracket with screws to secure it to a wall.
