I got some brass tubing fittings with the 73 that I'm selling. They have a gray plastic ring that the tubing goes in. I think the gray plastic is a part of the tubing lock, and then release system. I've never used this type of fitting. As I only use brass compression fittings. Are these fittings dependable? Or should I trash them? Bob Dunahugh

I've never seen one fail. We use them in a lot of machinery, and I have similar ones on my coach.
I much prefer the push to connect over the compression fittings.

I have used 1/4" airline fittings for at least 10 years. All kinds. The all
brass fittings without the sleeve that inserts into the tubing, fail just
about as often as the "push to seal/push to release" style fittings which
are made from a number of different materials, such as brass, and various
plastic like materials.
Absolutely the most reliable fittings I have found are the ALL BRASS
D.O.T. certified fittings that use a sleeve that inserts into the tubing
and a ferrule and compression nut to clamp onto the tubing and sleeve.
Properly used, they are as reliable as the tubing itself. They are the
only kind I regularly purchase and install into anything I have my
reputation riding on.
The fittings that are supplied with "Air Ride" brand equipment, I
remove and discard. They are mostly plastic junk.

The press in fitting is a good indoor application and when the tube is not
gouged, as the fiting does not apply enough compression to overcome the
souge.
The DOT rated I noticed are all rhe one with built in sleeve.
I read in a ad where one company now has the DOT rated Push in fitting.
I have had more issues with the Push in fittings not wanting to release.

Parker makes some nice brass ones, these are the ones I use in my coach suspension. They work great, and are used for semi-truck air brake systems so
very reliable.
I use a lot of the plastic ones in the shop and I've never had a single one fail.
The main thing is to use a razor cutter to cut the tube so it's Square. They will not work if the cut isn't square.

I have some HVAC fittings, but keep in mind, they operate a lot lower
pressure and vaccume.
We never cross them, not worth the bother.
