Silver Air line connector in question

Silver Air line connector in question

My son purchased tools from overseas (China) and is unable to connect it to the air compressor coupling. The connector's threads is 7/16 OD v. std 1/2" OD and the opening of the mouth of the connector is 1/4" ID versus standard 3/16" ID. Are there any couplers or converters to transition this to a std size? Picture attached.

Doug -

Your left one looks like what they call a schrader-shape.

The one on the right in your pic is usually called "industrial", the other common type being Tru-Flate, which most stores call "M" type. There are also "universal" I/M socket ones, which take either, but are not really universal.

Anyway, have fun and good luck finding what you need.

Same air fitting problem
by: Daren Blomerth

I made the same mistake trying to save some pennies. I did find: "Pipe 1/4" NPT female to M10 M10X1 male Metric Adapter Fitting" on eBay for almost the price of what I paid for the tool. I'm not sure it's the right size though

Non-U.S. standard connectors

Other pages on this site that will be useful to this questioner are those that explain couplers and connectors in detail.

Sometimes it's easier just to pick one standard, stock connectors and couplers only in that style, and toss all the rest.

Convert any Metric to Imperial sizes if that helps.

Might be best to look for the coupler to fit that male connector. Probably from the same source as the tools.

Bear in mind that the threads are almost certainly metric, so you want to figure out what it is in mm then look for that size and adapt to quarter inch NPT.

There's some info here:
