WORKPRO Digital Tire Pressure Gauge Kit 250 PSI — 12-piece inflator with brass chuck, 0.1 PSI precision

The WORKPRO 12PCS Digital Tire Pressure Gauge is a portable 250 PSI inflator and gauge kit with brass fittings, hose, and 11 accessories for accurate inflation, deflation and pressure checks.

This compact inflator-gauge combo delivers workshop-grade readings in a carry-ready kit. Built from aluminum alloy with brass components and rubber protection, it reads to 0.1 PSI and supports up to 250 PSI. The package includes a tailored set of adapters and tools so you can service cars, bikes, motorcycles, RVs and inflatables without hunting for extras.

How precise and reliable is the pressure reading?

The gauge is engineered for high precision with a fine 0.1 PSI display resolution and ±1% accuracy, making it suitable for routine vehicle maintenance and precise inflation jobs. A clear digital screen and an automatic backlight when air flow is detected help you read values quickly even in low light.

• 0.1 PSI display steps for fine adjustments
• ±1% accuracy for consistent, repeatable readings
• Automatic screen-on with airflow and 12-second auto-off to save battery
• Includes two AAA batteries to start right away

What components and adapters are included in the 12-piece kit?

The set comes with the digital inflator-gauge plus 11 useful accessories so you have the right connection for many valves and inflatables. Each accessory is selected to cover common vehicle valves and sports or pool equipment, reducing the need to buy extras.

• Brass twist-on air chuck for secure tire connections
• American 1/4” I/M male adapter and brass chuck for compressor compatibility
• Two rubber nozzles (long and short), inflation needle, tire-stem screwdriver, seal tape
• Four black valve caps to replace lost or damaged caps

How does it handle day-to-day use and durability?

Construction mixes aluminum alloy, brass and protective rubber, which improves resistance to drops, rust and jamming compared with basic iron nozzles. The ergonomic hose and secure connections reduce leaks and make repeated checks quick and efficient.

• Aluminum alloy body for lightweight toughness
• Brass fittings resist corrosion and wear
• Rubber overmolding protects against impacts and improves grip
• Rubber hose offers flexible access to awkward valve angles

Can I inflate and deflate tires with this tool?

Yes — the WORKPRO unit provides three functions: inflation, deflation and pressure measurement when connected to a standard 1/4" NPT air compressor. The valve control is simple to operate, but note an air compressor is required to supply pressurized air.

• 3-in-1 operation: inflate, deflate and gauge
• Connects to 1/4" NPT air compressors (compressor not included)
• Button-controlled valve for controlled airflow and quick pressure adjustment
• Clear digital readout for set-and-check workflows

Who this is for: This kit suits homeowners, DIY mechanics, mobile technicians and cyclists who want a robust, accurate inflator with the adapters to handle multiple valve types. It’s also useful for RV and truck owners who need higher-range pressure capability, and for anyone who prefers a portable, all-in-one solution with storage bag and spare accessories.
