Power Tank – Monster Valve Kit with Tap Install


Due to manufacturer delays, it may take some time for this product to be available to ship to you. We appreciate your patience.

 Monster Valves are an oversized secondary valve stem you install in your wheels. They make the fastest tire inflation system on the market even faster. Imagine airing down a 40 x 13.50 x 17 tire down 15 PSI in 17 seconds.


Monster Valve 1 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 the install video with the tire mounted.

Power Tank even include the tap for you! It 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.

We recommend adding a Tire Pressure Gauge (TPG) with a large, easy to read face to get accurate readings while you’re airing up and down. You’ll thank yourself when you see how quickly the pressure drops.
