1/4-Inch Brass Female Industrial Coupler, 10 Pack 1/4 Inch Air Hose Fittings NPT Female Quick Connector Air Coupler for Professional Jobsites and Automotive Shops

This air fittings work well with the couplers; no leaks and they are finished well.

I had a number of air lines and air hoses which had couplings which would leak. Cleaning the couplings did not help. My compressor was running frequently when I was not using my tools. These coupling provided 100% leak free connections and were very easy to connect and disconnect tools. I should have done this sooner. Great product at a reasonable price.

These parts come in bulk and have worked in many air lines of my shop. They are fairly tough for what they are, considering a customer parked right on top of one and it still functioned well. This product is a great fit and the male fitting fits perfectly into these with no extra slack. Being that these are brass they will not corrode anytime soon!

I've only tested one out of the ten in the pack, and it worked fine. No leaks, even when flexing the connection in every direction. To insert the plug on the tool or next hose, you have to pull back on the locking collar. This is a little less convenient than the more advanced push-and-click design, which allows you just to jam the connectors together without retracting the locking collar. Can't comment on how durable as I've only had it in service a few days. The main components are all brass, so they won't corrode. I would have rated 5 stars overall if it was the push-and-click design. Can't beat the price for a perfectly functional connector.

No leaks after months of use, very solid fittings !

These appear to be of good quality and more importantly fit my existing air couplers.

Worked as described. Used teflon tape on fittings. No leaks.

Fit well and do the job for the price
