Lock-On Air Chuck Adapter

This AUTO-VOX adapter converts a twist-on inflator connection to a lock-on style for faster tire inflation. The pack includes two brass adapters with a 12 cm rubber hose rated to 284 psi. A thumb-press mechanism secures the chuck to the valve without hand-holding. It suits bicycles, motorcycles and cars.

Upgrade From Screw-On Chucks

The adapter replaces the repetitive action of threading a chuck onto a Schrader valve. The jump is worth it when you inflate multiple tyres regularly and want a secure, leak-free seal in seconds. The fine 0.3" 32 TPI thread matches standard valve stems exactly. Heavy truck use is forbidden by the manufacturer.

Check Your Inflator And Valves

Verify your current inflator hose uses a compatible female twist-on fitting for the adapter's male thread. Confirm the tyre valves are standard Schrader type with the same fine thread pitch. Ensure your working pressure stays below 284 psi for safe operation.

Questions about this item

What thread size does the locking chuck use to match a standard Schrader valve?

The chuck has a .3" × 32 TPI fine thread that matches a standard Schrader tire valve exactly.

How do you attach the adapter to a twist-on inflator hose and what is the common mistake?

Screw the brass connector onto the inflator's twist-on fitting, then press the thumb lever to lock on the valve; the mistake is forgetting to press the lever and leaving it in the open position.

When should the rubber liner inside the nozzle be replaced?

Replace the liner when you notice air leaking at the valve seat or the rubber feels cracked and hard.
