Monster Valve Instructions

Thank you for your purchase of Power Tank Monster Valves.

Here you will find instructions for all current styles of Monster Valves. Monster Valves are sold in kits of four or five valves and include a Monster Chuck for airing up, an install tool (tap for MV1, Monster Key for MV3 and MV4), valve core removal tool, single-use packet of Loctite 243, and quick-release valve stem caps for your standard schrader valves. Optionally, you can add a HD Tire Pressure Gauge. 

Monster Valves are always installed as a secondary valve stem. This is so you can retain factory TPMS, so you can monitor your second-to-second tire pressure with an attached gauge, and so you have a backup way to air up your tire if you can not air up through the Monster Valve. 

Monster Valve 1 (MV1)

MV1s install into your wheels using threads that you drill and tap. A bright steel tap is included in kits of four or five Monster Valves. You will need medium strength Loctite 243 (included). MV1s can be installed with or without the tire on the wheel. We provide video instructions for both installation methods. Further down, you will see an additional install video of a MV1 into a Hutchinson Rock Monster Double Beadlock Wheel done by our friend Justin, at Krashfab Custom Fabrication.

Monster Valve 3 (MV3) and Monster Valve 4 - KMC Edition (MV4)

MV3s and MV4s are even easier to install into your wheels as they do not require tapping a hole. MV3s can be installed in nearly any wheel by simply drilling a hole. The MV4 is designed specifically for KMC Beadlock style wheels with dual valve stems and require no drilling or modification to the wheel to install. 

Both the MV3 and MV4 use a rubber grommet to create a leak-free seal. It is tightened from the back and both versions must be installed with the tire divorced from the wheel. 

We now include a single-use packet of Loctite 243. The instructions for using the Loctite is the same for the MV3 and MV4 installs and is found at the bottom of this page.

Note: We have recently added a rubber spacer to the MV4 to account for the recessed valve stem hole. Leave this spacer on the stem and follow the directions as normal. When installed, the rubber spacer will sit between the mushroom-shaped grommet and the valve.
