LOCKNFLATE® LOCKING AIR CHUCK - Straight, 90-Degree and XL

LockNFlate® Locking Air Chuck — Straight, 90°, and XL

Locks on. Stays on. Won’t leak. Six steel jaws create a secure, hands-free connection so air goes in the tire, not into the shop. Built for daily use in garages, fleets, and tire shops.

Choose Your Style Straight 90 Degree XL Large Bore Highlights

• Six steel jaws lock onto the valve for a secure, hands-free connection
• Durable, spring-loaded seal works with or without the valve core
• 1/4" NPT female thread; compatible with most standard air hoses
• Available in Open Flow and Closed Flow
• Choose Straight or 90° for tight spaces; XL fits large-bore valves

Variations (Choose One)

• Straight — Open Flow · Air passes through on or off the valve stem. Ideal for inflator gauges and battery inflators.
• Straight — Closed Flow · Air flows only when engaged on the valve. Best for direct compressor use.
• 90° — Open Flow · Right-angle body for tight or recessed valves on motorcycles, ATVs, and duals.
• 90° — Closed Flow · Right-angle body with flow that opens only on the valve. Great for compressor-only setups.
• XL Large Bore — Open Flow · For VG12/12V1 large-bore tire valves on heavy equipment, agriculture, and mining. Not for Schrader.
• XL Large Bore — Closed Flow · Same large-bore fit with flow that opens only on-valve. Not for Schrader.

Details

The LockNFlate® design uses a hardened steel collet and six jaws to grip the valve stem securely. This hands-free hold reduces leaks and blow-offs while keeping your fingers clear during inflation. Use Open Flow with inflator gauges, battery inflators, or automatic fill systems. Use Closed Flow when the chuck is connected directly to a compressor hose so air moves only when the chuck is engaged on the valve.

Pick Straight for standard access and the most compact profile. Choose 90° when clearance is limited or the valve angle makes straight-on connections difficult. Select XL only for large-bore valves (VG12/12V1). XL is purpose-built for heavy equipment and will not fit standard Schrader valves.
