I have received the products, and everything I want is very good. I tried it, and these accessories are very easy to connect and disconnect, and there is no leakage at all.
I especially like blowers and rubber- coated nozzles to clean the car vents and crevices.
Moreover, the tire chuck can inflate my car and remove the dust from the carpet. Very useful.
I’ve had more expensive ones before, but these are just as easy to use.

This air compressor accessories is very good. It is a set of 20 pieces, enough to use. It is the best great I have ever used. The metal is smooth and feels durable enough for many uses. The hose is of very good quality and long enough to connect with my air compressor. There are tire chuck and pencil tire gauge, which can inflate for my car. It is perfect.
There are many connectors, which is really great.

I really like the recoiled compressor hose with this air kit my wife gave for me. No leaks ( air tools should always have plumbers or teflon tape on any threads to make it truly air tight) and held up when I dropped it a few times from waist height onto concrete. Haven’t used all components yet. So for so good, prefect little kit.

I bought this to use with a small compressor, I’m using these pretty often, it has worked great so far with no issues, connecting and disconnecting is extremely easy. No leaks at all. I used the kit to replace all my quick connect part and air tool end pieces.

Solid cheap kit. For loaning tools I need something that either takes abuse or is low cost enough that it doesn’t matter. This air chuck kit is both. Fittings are plated so don’t leave ’em out. This kit stays with a filled air tank in the box of a ranch truck used by staff so that I never get the radio call for a flat tire at 4AM. Also used to blow lines for winterizing. I keep the nylon hose in an old pillow-case with a thru-hole in the bottom so it doesn’t get tangled, crushed, or kinked. Useful$20 product.
