LockNFlate PRO Analog Tire Inflator Gauge with LockNFlate® Locking Air Chuck

Always Ready When You Are

The LockNFlate® PRO Analog Tire Inflator Gauge is built for dependable tire inflation without relying on batteries or electronics. The large 3" mechanical dial provides clear pressure readings instantly, making it ideal for drivers, equipment owners, and shop environments where tools need to work every time you reach for them.

Whether you're topping off tires in the driveway or maintaining vehicles in a professional workspace, the LockNFlate® PRO Analog delivers fast, reliable inflation performance with a simple, durable mechanical design.

The LockNFlate® Air Chuck Advantage

Standard open-flow air chucks require constant pressure against the valve stem. Let go, and air escapes. The included LockNFlate® Locking Air Chuck eliminates that frustration completely. Its hardened steel jaws lock onto any standard Schrader valve (VG8/8V1 threads) with a press-and-click motion, creating a secure hands-free seal rated to 150 PSI.

A spring-loaded TPU seal allows inflation with or without the valve core installed, and the handle-mounted magnetic dock keeps the chuck secured between uses so it is always where you left it.

Large Analog Dial for Fast, Clear Readings

The oversized 3" analog gauge measures tire pressure from 7–174 PSI (0.5–12 BAR) and is easy to read at a glance while inflating tires. Unlike digital gauges, the mechanical dial responds instantly and does not rely on batteries, making it a dependable choice for everyday garage use and professional environments.

A protective rubber shroud surrounds the gauge to help guard it from impacts during normal shop and vehicle maintenance work.

A Hose Built for Real Use

The included 32" (800 mm) hybrid polymer hose provides extended reach around larger wheels and tight valve locations while staying flexible in cold weather conditions. The integrated inline swivel helps reduce hose twisting during use, improving handling and extending hose life.

Bend guards reinforce both hose ends — the exact points where standard hoses typically fail first.

Mechanical Simplicity. Professional Reliability.

Because the LockNFlate® PRO Analog Tire Inflator Gauge uses a mechanical pressure dial instead of electronics, it is always ready to use without charging or replacing batteries. Combined with the locking air chuck, extra-long hose, and durable protective shroud, it provides a reliable inflation solution for vehicles, trailers, and shop equipment.
