SoBoBoS Tire Inflator Adapter 2-Pack Brass Clip-On Lock-On Schrader Valves, 250 PSI Open-Flow

SoBoBoS 2-Pack Tire Air Chuck converts a compatible screw-on inflator chuck into a clip-on, lock-on Schrader valve adapter for quicker, hands-free inflation.

When you want faster, more reliable inflation with portable or electric inflators, this pair of brass clip-on adapters lets you swap a screw-on hose end for a lock-on connection to standard Schrader valves. Built with a threaded male end that screws into a matching female screw-on inflator chuck and a clip-on tire-side fitting, the adapters create a steadier seal for cars, SUVs, trucks, motorcycles, and other vehicles that use Schrader stems. They are open-flow style (no internal shutoff), so start and stop air at the inflator itself.

How do I install the SoBoBoS adapter on my inflator?

Installation is straightforward: thread the male end into the inflator’s female screw-on chuck until snug, then use the clip-on end on the tire’s Schrader valve. Keep the adapter straight while seating to form the best seal and avoid leaks.

• Screw the 0.305"-32 TPI (8V1) male thread into the inflator’s female chuck.
• Press the lever, push the clip-on fully onto the Schrader stem, then release to lock.
• Begin inflation from the inflator; stop at recommended pressure and remove by pressing the lever.
• Reseat if air escapes; recessed valves may require extra clearance to operate the lever.

Which valve types and inflators work with this adapter?

This adapter is designed specifically for standard Schrader valves and inflators with a female 0.305"-32 TPI (ISO 4570 8V1) screw-on chuck. It will not work with Presta bicycle valves, 1/4" NPT shop compressor fittings, or inflators lacking the matching threaded chuck.

• Compatible with Schrader (car-style) valve stems only.
• Requires an inflator whose hose end has a female 0.305"-32 TPI (8V1) thread.
• Not a closed-flow or self-shutting chuck; control airflow at the inflator.
• Not compatible with standard industrial compressor threads like 1/4" NPT.

What materials and pressure ratings should I expect?

The adapters pair a corrosion-resistant brass body with a flexible silicone seal for repeated use and a better seating surface against Schrader stems. They are open-flow fittings rated for typical automotive inflation tasks up to 250 PSI.

• Body: durable brass resistant to rust and wear.
• Seal: silicone gasket to reduce air loss when fully seated.
• Flow type: open-flow — start/stop from the inflator unit.
• Maximum working pressure: 250 PSI.

Will these adapters help when I need hands-free inflation?

Yes — the clip-on lock keeps the chuck attached while you operate the inflator, so you won’t need to hold the hose against the valve. Because there’s no internal shutoff, you must monitor inflation from your inflator or gauge.

• Lock-on clip reduces the need to hold the valve during inflation.
• Helps limit air loss when attaching and removing the chuck.
• Two-pack gives a spare for another inflator or a replacement on the go.
• Not an automatic-pressure cutoff; use a gauge or inflator settings to stop.

Who is this for: Drivers, DIY mechanics, and anyone using portable or electric tire inflators who wants quicker connections to Schrader valves will benefit from the SoBoBoS 2-pack adapter. It's ideal if your inflator currently uses a screw-on chuck and you prefer a clip-on, lockable attachment for hands-free inflation. Avoid buying if your gear uses Presta valves or non-matching inflator threads — always confirm your inflator has a female 0.305"-32 TPI (ISO 4570 8V1) screw-on chuck before ordering.
