First Choice Pneumatic Tanks

[Gregor]

We got some of these black Clippard Pneumatic Tanks off of FIRST Choice.

Out of the box they looked like this. They come with a little push in insert.

This is the tank without the insert, and this is the insert removed.

We expected that the tanks would have a threaded port, but they came with this instead. Tubing seems to fit into the little insert, but the insert seems to detach from the tank very easily.

Are we doing something wrong? Does the tube just press into the insert which presses into the tank?

[MrBasse]

It looks like it does, but does the insert have teeth or barbs in it? If the opening it fits into is tapered, when you insert the hose and bottom it in the insert and tug on the hose the teeth should bite in. That is how the push to connect fittings work but they generally have an o-ring or seal as well. With no hose, the caps can be removed fairly easily.

The description at andymark is wrong. this is the clippard description of the part. The fitting is a push-to-fit for 1/4" tubing. It should be compatible with the other fittings that accept the "Bare" tubing also common in FRC. The little thing you removed is a plug to prevent contamination during the time the fitting does not have a tube in it. I cannot tell if there is another port at the other end. They do not use the plural for the description. You can tell by looking at it. I will be envying you as I put threaded fittings in both ends of my white ones.

The little white fittings are push to connect. This saves the hassle and weight of adding brass.

Both ends are identical. I thought the little insert was for shipong too, but the tube is too small for the hole in the tank without the fitting. The insert feels like a push to fit connection, but it seems really easy for the insert to come out of the tank.

The insert isn't for shipping, that is the collet that grabs the tube. I worked for Parker and we had similar collets in out Push to Connect line. Leave it in and push the tube in, be sure to give it a tug to seat the teeth into the hose. If you remove the hose from the fitting more than once be sure to trim the end for a clean sealing edge.
