Look really good quality..
Not able to review these as was not compatible with my equipment.. not clear on listing which fitting they are, thought they were Euro but was sent something that looked similar...my fault, no blame on seller, should have asked first...but have to say looked excellent quality, very pretty, if you had a mixture of fitting you could pick these out straight away..

Compressed-air fittings
These fittings are well made and to exacting tolerances. The metallic red finish gives my paint shop a really professional appearance. Very satisfying indeed, and I shallbe ordering some more of them.

These are not UK 1/4" BSP standard threads. No good for the UK
While these air line fittings work well they are not 1/4" BSP. They are 1/4" NPT which I think is an American standard. These will not work with air tools supplied to the UK and anywhere else that uses the BSP standard. Threads look similar but the thread pitch and height are slightly different. They look great though. I was very sad to return them to Amazon.

MILTON PRODUCTS ON TOP!
After using them for a few weeks, I can confidently say they deserve a solid 5-star rating. First off, the durability of these couplers and plugs is impressive. They feel solid and well-made, which gives me peace of mind knowing they can withstand regular use in my workshop. The thread quality is exceptional; they screw on smoothly without any cross-threading, making the connection process hassle-free. One of the standout features for me is how well they fit with my existing air hoses and tools. These couplers provide a secure connection, minimizing any air leaks during operation. Lastly, the ease of use is a game-changer. I can quickly swap tools without fumbling around, which saves me time and frustration. Overall, if you’re in the market for reliable air tool couplers, I highly recommend giving Milton a try. The quality is truly amazing!

Adaptors that work.
A really high grade adaptor kit - allowing the conversion between old style and ARB connectors. We've used it to adapt all sorts of compressors and hoses. Lots of spare parts.
