Power Tank Monster Valve Tap3 Single High-Flow Tire Valve Stem

The Power Tank Monster Valve Tap3 is a single 3/8-24 straight-thread high-flow valve stem machined from 7018 aluminum for installation into steel or aluminum wheels as a primary or secondary valve stem. Weighing just 1.1 oz, it enables rapid tire deflation and inflation without requiring tire removal from the rim. This listing is a spare or replacement unit and does not include the 'Q' drill bit, 3/8-24 tap, installation key, or Monster Chuck.

High-Flow Design That Outpaces Standard Valve Stems

The Monster Valve Tap3's oversized bore moves air dramatically faster than a conventional Schrader valve. A single Monster Valve delivers comparable flow to four standard Schrader valves, which means a large tire can air down from 35 psi to 10 psi in under 30 seconds and air back up in approximately 45 seconds when paired with a Monster Chuck and a Power Tank CO2 system. That speed matters on a trail where airing down before a technical section and airing back up before returning to pavement is a routine stop, not a lengthy delay.

Rigid, Lightweight Construction That Does Not Require Rebalancing

The Monster Valve Tap3 body, collar, and dust cap are machined from aluminum, keeping the total valve weight at 1.1 oz. At that weight, adding the valve as a second stem does not require a tire rebalance. The 3/8-24 straight-thread design is five times stiffer than a standard metal valve stem, resisting flex and fatigue at the wheel during off-road use. Straight threads are also easier to start cleanly than tapered NPT threads and eliminate the risk of over-threading during installation.

Installs Without Removing the Tire

The Monster Valve Tap3 threads into a drilled and tapped hole in the wheel. The installation process (drill with a 'Q' bit, tap 3/8-24 threads, thread in the valve) can be completed with the tire still mounted on the rim. Because this listing is a spare or replacement valve, the 'Q' drill bit, 3/8-24 tap, and installation key are not included; those tools are available separately as the Monster Valve Tap 3/8-24 and 'Q' Drill Bit Combo.

Specifications

Who This Is For and Isn't

The Monster Valve Tap3 single unit suits overlanders and off-road drivers who already own the Monster Valve installation tools (the 'Q' drill bit, 3/8-24 tap, and installation key) and need a spare or replacement 3/8-24 tap-style valve stem for a steel or aluminum wheel. It also works as a first valve for buyers purchasing the install tools separately.

This listing does not include the 'Q' drill bit, 3/8-24 tap, installation key, or Monster Chuck. Buyers starting a fresh install should consider the 5-pack with install tools instead. The Monster Valve Tap3 is not compatible with wheels designed for the Monster Valve Primary (standard valve stem mount), Flat2 (dual valve stem), or LOCK (Icon Pro InnerLock) styles. The warranty is void if the valve is used with balancing beads.

Common Questions

What is included with this single Monster Valve Tap3?

This listing includes one Monster Valve Tap3 (3/8-24) valve stem only. The 'Q' drill bit, 3/8-24 tap, installation key, and Monster Chuck are not included. Buyers who need installation tools should look at the Monster Valve Tap 3/8-24 and 'Q' Drill Bit Combo or the 5-pack with install tools, both available separately.

Will the Monster Valve Tap3 fit my wheels?

The Monster Valve Tap3 installs into steel or aluminum wheels by drilling a hole with a 'Q' bit and tapping 3/8-24 straight threads. A Monster Valve Fit Kit is available to test compatibility across multiple Monster Valve styles before committing to an install. Wheels designed for the Primary, Flat2, or LOCK Monster Valve styles use different mounting methods and are not compatible with the Tap3.

Is the Monster Valve Tap3 compatible with TPMS sensors?

Yes. When the Monster Valve Tap3 is installed as a secondary valve stem alongside the factory Schrader valve, the existing TPMS sensor remains on the Schrader stem and continues to function normally. If the Monster Valve is installed as the only valve stem, a TPMS bracket is available to reuse the factory sensor; some vehicles may require an aftermarket TPMS sensor.

Can the Monster Valve Tap3 be used with balancing beads?

No. The Monster Valve Tap3 warranty is void if the valve is used with balancing beads. Buyers running bead-balanced tires should not install this valve stem.

How difficult is it to install the Monster Valve Tap3?

Installation requires drilling a hole in the wheel with a 'Q' drill bit, tapping 3/8-24 straight threads with the matching tap, and threading in the valve, all with the tire still mounted on the rim. The 3/8-24 straight thread is easier to start cleanly than a tapered NPT thread and does not require precise depth control to avoid over-threading. The tools are not included with this single-valve listing and must be purchased separately.
