Good size until I try to put a thermometer bulb through this for a guage. Did not work.

Works for the Smittybilt Pump Mod to add a pressure cutoff switch and gain the ability to use a regular air chuck with gauge. Definitely recommend this fitting for that purpose.

I bought this based on other reviews to convert my Smittybilt air compressor from the Japanese connections and flimsy hose that came with it to the more robust USA set up. Works perfect. Early delivery was much appreciated.

It was exactly what i ordered, but did not fit the smitty built compressor. They evidently made them with 2 different thread pitch. 12mm1.25 and 12mm1.00

I used this on my SmittyBilt compressor to allow for regular air fittings and hoses.Such a dream now. No more melting yellow hoses or such.

Used to convert a Iron man Pro 4x4 air compressor to standard 1/4 fittings. Couldn't find this part anywhere else. Seems seriously over priced, however it does work and got the job done.
