Automatic Tire Deflator Kit, 4-Pack, Adjustable 10-30 PSI

About this item

• SET-AND-FORGET AUTO-STOP DEFLATOR — Pre-set your target PSI on the brass body, lock the double-nut, screw this automatic tire deflator and valve stem tool onto all 4 valves, and walk away. The check-ball mechanism stops airflow at your set pressure (±2 PSI). Note: read the PSI mark on the body, NOT on top of the lock ring — that is the most common cause of inaccurate readings.
• 4 TIRES IN UNDER 3 MINUTES — A faster, hands-free tire air down tool than crouching by each tire with a pen or valve core remover. Screw four on at once, prep your recovery gear, walk back to an aired-down rig. Designed to deflate 35-inch tires from 38 PSI to about 20 PSI in roughly 3 minutes per tire — works on stock SUVs, 4x4 trucks, ATV, UTV, RV, dual-sport bikes, and dually trucks.
• ALUMINUM ALLOY VALVE CAPS THAT WONT FUSE — Generic metal valve caps can corrode and fuse to tire stems after exposure to road salt, sand, and beach environments. Our kit includes 4 aluminum alloy valve caps built to resist corrosion in harsh off-road conditions, plus a soft-lined zippered pouch with a clip loop — clean offroad accessories for your glovebox or door pocket.
• LOCK-IN PSI WITH NO DRIFT — Our double lock-nut valve adjustment tool design holds your set PSI in place when you screw the deflator onto the valve stem under torque — the setting holds firmly during installation. Designed for consistent performance across all 4 units within the 10-30 PSI range, typical ±1.5 to 2 PSI. Solid brass body with stainless-steel spring built for repeated trail and beach use.
• ESSENTIAL OFFROAD AND OVERLANDING GEAR — Whether you air down for sand dunes, rock crawling, mud trails, snow runs, beach driving, or forest service roads, these off road tire deflators replace the slow valve-core method with a hands-free upgrade. A clean gift for overland enthusiasts, off-road newbies, and trail buddies — backed by AltitudeCraft customer support.
