Lock-On Air Chucks
1/4″ FNPT Lock-on Air Chuck
This 1/4 FNPT lock-on air chuck combines a female threaded inlet with a locking tire-valve connection. Its lock-on function holds the chuck on the valve for hands-free inflation, helping operators manage the connected hose and inflator during tire service. For workshop suppliers and distributors, the two connection points make selection straightforward: match the 1/4 FNPT inlet to the air-line fitting, then check the locking head against the intended tire valve.

Overview
Choose this locking air chuck when the purchasing requirement calls for a 1/4 FNPT inlet and a head that stays attached to the tire valve during inflation. The female connection identifies the air-line side of the product, while the lock-on head performs the valve-side task. Keeping those two interfaces separate in a specification helps distributors and service teams compare chucks that may look similar but connect differently.
The hands-free inflation function is useful in tire-service setups where an operator also needs to handle the hose or inflator control. For a replacement order, provide the existing fitting details and valve application alongside the required quantity. For an equipment or private-label project, an approved sample or drawing can define the final assembly requirements. Request the applicable flow configuration and working-pressure details when matching this chuck to a particular system, so the quotation reflects the complete application.
Applications
• Workshop tire-inflation setups requiring a 1/4 FNPT inlet and a locking valve connection.
• Distributor replacement assortments organized by inlet thread and chuck attachment style.
• OEM hose or inflator assemblies specified around this female-threaded lock-on configuration.

Product FAQs
What does the 1/4 FNPT connection refer to?
It identifies the female threaded inlet on the air-line side of the chuck. It does not describe the tire valve. Match this inlet to the mating fitting in your hose or inflator assembly before selecting the product.
How does the lock-on function help during inflation?
The head locks onto the tire valve so the operator does not need to keep pressing the chuck against it throughout inflation. The operator can then manage the hose and inflator controls while monitoring the tire-service task.
Is this an open-flow or closed-flow air chuck?
The current specification identifies the 1/4 FNPT inlet and lock-on function, but does not state the flow configuration. Include your inflator or hose arrangement in the inquiry so the required open-flow or closed-flow behavior can be checked.
What should a distributor include in a quotation request?
Include the required quantity, mating inlet fitting, intended tire valve and inflation setup. An existing sample or drawing is helpful for replacement projects. Add any pressure, flow and packaging requirements so the quotation can address the intended application.
