Air blow gun

[Bus Driver]

The two-stage compressor in the shop pumps up to 175 PSI at shutoff. The plastic body Harbor Freight blow gun specifies 90PSI maximum. They are not kidding. Sometimes I do want the full pressure plus walking back to the regulator often is not that much fun nor easy anymore.
Recently the molded-in brass fitting on the HF gun blew out. The fitting stayed with the hose. No injury nor property damage but a bit of surprise involved.
Looking on eBay for a suitable gun may be futile. The metal ones, probably cast "white metal", indicate 1.0Mpa maximum working pressure. That is 150 PSI. Not sure what safety factor is built in, if any.

might check Northern Tool, while their products are a little higher, they are also a little better.

Do go to Northern a few times a year but their location is not very convenient for me. The Ironton brand appears to be their house brand. I have tried just a few items of that brand and they were absolute junk. Would not accept another of the items I bought if they were offered as gifts.
So it is possible that I will miss out on some good stuff of the same brand because I do not buy anything with that brand on it.

I like to pick up the old metal body blow guns at flea markets/garage sales. These are the ones that were produced before the low flow/psi output safety mandate. The last one I bought was an all stainless steel body. I put a new QD fitting on it and it worked perfect. Blows like nobody's business at 175 psi.

Is there a reason you need that much pressure before it shuts off. Adjustment should be possible. Mine quits at 125 psi and I haven't needed more air flow. Just wondering.

So I bought one online that looks like this one-- but from another seller.

Selected this one for the photo. The air connection probably is a quick-coupler but not like any I have seen previously. And that fitting is epoxied in place at the supplier on mine. So they did not plan for change to be made.
Anyone seen a quick coupler of this configuration?
I contacted the seller from whom I bought and his English is only slightly better than my (non-existent) Chinese. No help.

Hopefully you could just unscrew that fitting and screw in one that matches your hose.

Probably NITTO-Japanese type quick connector. You may be better off buying a different gun.

That looks like it. The mating component is perhaps SM-20 based on one site I found.
