Monster Valve Tap (or MV-Tap, formerly MV1) Tire Deflator Kit from Power Tank. Monster Valves are over sized, light-weight, yet strong valve stems that you install as a second stem to your wheel. Made from 7018 aluminum, they are the fastest tire deflation and inflation product on the market.

Imagine airing down a 40"x13.5"x17" tire from 35 psi down to 10 psi in under 30 sec. This kit also includes a Monster Chuck which, when used with a Power Tank, will inflate that same tire in 45 sec.

They are easy to install into steel or aluminum wheels. Just drill a 7/16" hole, tap 1/4" NPT threads, and screw them in. Done. You don't even have to remove your tire from the rim. Check out our install video with the tire mounted here.

We even include the tap for you! Ours is a high quality bright steel tap. The quality of your tap directly relates to the quality of your threads. Poor threads are the most common cause of leaks.

With an all aluminum construction the total weight of each valve is a mere 1.1 oz. and does not require a tire rebalancing. Due to its construction, it is 5 times stiffer than a standard metal valve.
