Pipe 1/4" NPT Male X M12 M12X1 Male Metric Adapter Fitting Oil Fuel Air

I bought a Harbor Freight air fill tool for airing up my car and RV tires. I use a Block brand water separator/filter to keep water out of my tires and to not rust my rims. The male air chuck fitting on the body of the air fill tool has a 12mm x 1.0 straight male thread on it. I needed an adapter fitting to go from the air chuck to a male 1/4" NPT threaded fitting. This is the only fitting with that combination of threads on it. I need to machine an o-ring boss on the 12 mm x 1.0 straight thread to accommodate an o-ring at the inlet of the air tool to seal it up like the original male air chuck inlet fitting. That will allow me to mount the Block water trap/filter that requires this threaded combination on the body of the new air fill tool.

so it shows 3 in the picture but your only getting 1 piece for the money not 3

Seller puts a picture of 3, but this is only for one. Better to put 3 separate pictures of one item in order to show 3 viewing angles. Metal is very soft. A chunk of the hex nut portion broke off under my wrench at a reasonable torque while tightening onto fixture. My wrench did not “slip”, but rather the part gave way under the pressure of the wrench. This is the softest brass I have ever worked with.

High quality
