WYNNsky Air Coupler and Plug Kit, 1/4 Inch NPT Air Fittings Industrial Type, 7 Piece Air Compressor Accessories Kit

I have used all of the pieces provided and have not had a single issue. The pieces that come coated do not leak after a week of use with nailers and other tools. I used 8-10 layers of thin ptfe tape on the non-coated connectors and I have not had any leaks with those either. All connections are whisper quiet and I don't lose any pressure over time. Even if the coated bits leak I'll just tape them up as this is a great price. Great purchase and will buy again if needed.

I needs some different ends for my air hose and devices.It had what I needed so I am pleased with them. The have sealing compound on the threaded ends so when you hook them you and tighten them - no leaks.

cheaply made and the female couplers leak internally.. they do work but you get what you pay for! Do your compressor a favour and spend a couple extra bucks and get good couplers and fitting.

Not bad product for $ involved . My only caveat is that tolerances might be of on female connector . A little plastic tap solved problem . Would buy again

Good seller, fast delivery, good quality of product as described
