Pipe Test Plugs
Pipe test plugs are internal and external stoppers that can test the strength and integrity of piping and tubing with more accuracy. High-pressure air is pumped into piping, with a pipe plug or test plug sealing the open end, so the internal pipe pressure can be measured more precisely. Like the name implies, an inflatable pipe plug allows the tester to control the in and outflow pressure with more precision. Zoro also has a great selection of PVC pipe fittings, brass fittings, and flexible pipe fittings too.
