LockNFlate 90° Air Chuck for Schrader Valves - Open Flow 6-Steel Jaw, 1/4" NPT, 150 PSI

The LockNFlate® 90-Degree Air Chuck (Open Flow) is a compact right-angle Schrader valve connector with six steel jaws and an open-through design for fast, hands-free inflation of hard-to-reach tires.

This precision air chuck combines a low-profile 90° angle with a durable six-jaw locking collet and a spring-loaded TPU seal so you can attach to motorcycle, bicycle, ATV and automotive Schrader valves quickly and hold pressure while you work. The Open Flow variant passes air through the chuck continuously, making it ideal for use with hand or foot inflators, inline gauges, and automatic tire inflators where continuous airflow is required.

How does the six-steel-jaw lock make inflating easier?

The six jaws clamp evenly around the Schrader valve stem for a secure, hands-free connection that resists slipping under pressure. This design reduces valve leaks and lets you walk away or use both hands for gauges and inflators without worrying about the chuck coming loose.

• Six hardened steel jaws for stable, symmetrical grip
• Spring-loaded action keeps constant contact under vibration
• Works with standard Schrader valve stems (VG8/8V1 threads)

Why choose the 90° right-angle shape for tires and tight spaces?

The compact 90° profile clears spokes, swingarms, brake calipers and other obstructions that block straight chucks. That makes it far easier to reach valves on motorcycles, bicycles, ATVs, lawn equipment and many dual-sport wheels without awkward repositioning.

• Right-angle body fits tight valve recesses
• Low-profile design prevents interference with nearby components
• Ideal for vertical, recessed, or angled valve orientations

Is this chuck compatible with my shop equipment and pressure needs?

Yes — the LockNFlate 90° Open Flow chuck uses a 1/4” NPT thread and is rated to 150 PSI, so it pairs with most domestic compressor lines, portable inflators, gauges and shop air hoses. The open-flow configuration allows uninterrupted airflow when using hand- or foot-operated inflators or automatic tire inflators.

• 1/4” NPT thread fits common air hoses and fittings
• 150 PSI maximum working pressure for garage and shop systems
• Open Flow passes air through for continuous inflation

How durable is the LockNFlate chuck in everyday use?

Built with a hardened steel collet and a robust TPU sealing element, this chuck stands up to frequent attachments and shop environments. Materials resist wear from repeated use, and the construction tolerates the rough handling typical in garages and service bays.

• Hardened steel collet for long wear life
• Spring-loaded TPU seal for reliable airtight contact
• Constructed for commercial and home shop use

Who this is for: The LockNFlate® 90-Degree Air Chuck (Open Flow) is aimed at motorcyclists, bicycle mechanics, ATV riders, home garage enthusiasts and professional technicians who need a dependable, low-profile Schrader connector for difficult-to-reach valve stems. Choose the Open Flow model if you want continuous air passage for use with hand/foot pumps, inline gauges, or automatic inflators; select Closed Flow when you need the chuck to block air until the valve is engaged directly from a compressor hose.
