R9030S-113 Locking Lever Air Chucks

Sharing the same locking philosophy as its clip-style counterpart, the R9030S-113 uses a screw-on holder to secure the chuck onto the valve stem, giving technicians a twist-and-lock connection for 1/4-inch hose setups.

The threaded engagement provides a solid mechanical hold that some technicians prefer over a spring clip, particularly on valve stems where a snap-on connection tends to work loose during extended fill times.

Once threaded into place, the chuck stays put through the full inflation cycle, freeing the technician to step away or attend to another task rather than holding the chuck steady by hand.
