Product identity
This PowerMate 072-0006RP is a compressor tank drain valve with a 1/4 inch NPT thread and thumbscrew operation. It suits owners of compatible Dewalt, Industrial Air, Porter Cable and Powermate compressors who need a direct replacement.
Thermals, noise and power
The valve is a passive mechanical component, so it produces no heat, draws no power and generates no noise during normal compressor cycling. Installation requires only hand tightening onto the existing tank port.
Deciding specification
The 1/4 inch NPT thread size determines whether this valve fits your tank; verify the port on your unit before ordering. Buyers whose compressors use a different thread standard cannot use this part.

Questions about this item
How do I install the 1/4 NPT thumbscrew drain valve without cross-threading?
Thread the valve into the tank port by hand until the NPT taper seats, then give a final quarter-turn with fingers only — no wrench — to avoid stripping the soft brass threads.
What part will need replacement after repeated draining cycles?
The internal rubber seal deforms over time; keep a spare 072-0006RP on hand so you can swap it when moisture starts seeping past the closed thumbscrew.
At what pressure does the thumbscrew become too stiff to open by hand?
Above roughly 90 psi the spring-loaded poppet pushes back hard enough that most users need pliers, so bleed the tank lower before attempting to open.
