Trailhead Tire Deflators 4 pack from Power Tank. These are the Best automatic tire deflators on the market. They are made from machined aluminum and then anodized. They are accurate to +/- 1 PSI and are completely rebuildable if they get dirty. I've owned a set for years and had to rebuild them once. We recommend these for up to 35 inch tires.
Screw these on to your valve stems when you get to the trailhead. Start the trail while they are still deflating and you should be at the perfect tire pressure when you get to the first obstacle. Unscrew them and put them away before you rub up against a rock and break your valve stem. Easy.
The different colors allow you to keep multiple sets at different pressures, based on the terrain or trail you decide to conquer that day. These are high-pressure deflators and can be set between 15 and 40 psi. For lower pressures, check out our exclusive new black deflators which feature the Power Tank logo etched in the side and include a digital tire pressure gauge (0-100 psi) instead of the standard pencil pressure gauge. They can be set between 5 and 20 psi.
To Clean: Remove top set screw. Remove screw, spring, and seat ball. Spray cleaner (WD-40, brake clean, carb cleaner) through aluminum body to remove any grit and debris. Blow out any excess solvent or oil with high pressure air. Wipe the plastic seat clean with a clean rag. Do not use solvent. Put a light film of Vaseline to the round seat surface and reassemble parts. Readjust the pressure setting. Done.
Hint: When disassembling, count the number of turns to remove the set screw. When reassembling you know how many turns to go in to get it close to where you had it.
Note: Low stock, final inventory - when these sell out, they're gone for good!
