LockNFlate LNL65012 Closed-Flow 90° Air Chuck

The LockNFlate LNL65012 is a 90-degree, closed-flow locking air chuck designed for fast, hands-free tire inflation directly from a compressor, hose whip, or manual inflator. A six-jaw steel collet clamps evenly around any Schrader valve to create a secure, leak-free seal. Lock it on, stand clear, and fill with confidence; when you’re done, flip the lever for a clean release without twisting or side-loading the stem. Because it’s closed flow, air does not pass until the chuck is attached and locked to the valve. That behavior is ideal for shop hoses and inflators without a bleed path, multi-hose manifolds, and service trucks where constant air would be unsafe or wasteful.

A spring-loaded TPU sealing face presses squarely on the stem—whether the valve core is installed or removed—while the hardened steel collet withstands daily lock/unlock cycles in busy tire bays. The 90° body helps you reach recessed stems on alloy wheels, duals, and tight wheel openings where a straight chuck won’t line up. A standard 1/4″ NPT inlet threads onto common air lines and tire inflator gauges. With a 150 PSI maximum operating rating, the LNL65012 fits garage and industrial airline systems used for cars, light trucks, trailers, shop carts, and equipment tires.

Usage tip: If you’re using a battery inflator or an inflator gauge that requires constant airflow, choose an open-flow LockNFlate model (e.g., LNL65011)

LockNFlate Closed-Flow 90° Air Chuck At a Glance

• Six-jaw locking collet: Uniform grip on Schrader valves for a secure, hands-free connection.
• Closed-flow design: Air flows only when locked to the valve—safer for direct-from-compressor setups and multi-hose inflators.
• 90° body for access: Clears wheel faces and center caps; ideal for duals and recessed stems.
• Spring-loaded TPU seal: Maintains an airtight interface with the valve core in or out.
• 1/4″ NPT connection: Threads to most air hoses, whips, and manual inflators.
• 150 PSI rating: Suitable for garage and industrial airline systems.
• Quick lever release: Smooth disconnect that protects stems from side loading.
• Heavy-duty construction: Hardened steel collet and durable housing for everyday use.

Markets

• Tire Shops & Service Bays Hands-free, leak-free hookups that keep inflation stations moving.
• Fleet Maintenance Reliable connection for mixed vehicles and trailer tires across the yard.
• Construction & Agriculture Secure filling on equipment tires in the shop or field.
• Industrial & Facilities Standardizes inflation at maintenance air stations for carts and utility vehicles.
• Municipal & Public Works Consistent, safe inflation tool for department vehicles and small equipment.
• DIY & Home Garages Professional-grade air chuck for compressors and wall-air systems.

Technicians in these environments need an air chuck that attaches once, seals tight, and stays put while pressure rises. The LNL65012’s six jaws grip the Schrader valve evenly to stop hissing and prevent pop-offs. Closed-flow operation keeps air contained until the connection is secure, which is especially helpful when running off a compressor or a multi-hose inflation rig. The 90-degree head reaches stems a straight chuck can’t, and the 1/4″ NPT inlet ties into existing hose whips and gauges in seconds. The end result is faster setups, safer stand-back inflation, and fewer callbacks from under-inflated tires or damaged stems.

Why Professionals Choose the LockNFlate Closed-Flow 90° Air Chuck

Shops choose the LNL65012 because it combines secure locking with the safety of closed-flow operation. The six-jaw collet grips a Schrader stem evenly, so the connection stays sealed and the gauge reading stabilizes while the tire fills. The right-angle body clears wheel obstructions, and the quick lever release avoids stem damage when you disconnect. A standard 1/4″ NPT inlet means it drops into existing hose assemblies without adapters, and the 150 PSI rating suits typical shop air. For anyone searching for a locking air chuck that works directly off a compressor, handles tight stem locations, and keeps air under control until you’re clipped on, the LNL65012 provides dependable, day-to-day performance with clean results.
