HongBoW 2pcs BSP NPT Adapter British To US Gauge Sensor Sender Adapter Reducer Brass Pipe Fitting Adapter 1/4 BSPT Male x 1/4 NPT Female

worked perfect

Fit well! Didn’t leak at all and the brass material will be good to fight off rust from the Midwest!

Nothing really to say about it. It works as advertised, no failures or cracks in the casting or anything like that.

HongBoW Brass 1/4" BSPT Male to 1/4" Female NPT adapter is a quality product. The 1/4" BSPT British Male thread worked with my Nitto Kohki quick connect and the Female NPT connects to USA pneumatic air hose.

This worked perfectly. I have a 8 gallon compressor hooked to a retractable hose reel. I was able to join my airbrush hose to the hose reel hose via normal quick connect perfectly. I did use vinyl tape just for good measure but I can now take my airbrush 30 feet away. The only bad part is my pressure adjusting is at the compressor. But that's just a minor inconvenience.

Not a huge application for these in the US, but they mate perfectly with the various "10L fluid extractor/dispsensers" sold on Amazon. Who knows why those things all use BSP threads, but they do. Some people will just force NPT fittings on, but this adapter lets you mate common shop air quick disconnect fittings to those fluid extractors. Make your future life easier and do it right the first time.

Female tapered connection end ID at face is the same as the OD on the male tapered connection starting thread of my hose fitting so the connection would not engage. 1/8" male connection fits correctly. Photo 1 new adaptor and hose threads will not engage. Old adaptor next to them. Photos 2 old adaptor threads engaged. Photo 3 end view of both adaptors and hose end. To the eye the starting thread diameters are indistinguishable.

I got an air nozzle with weird japanese threads. This worked to adapt it to american type threads.
