Issue With Cylinder

So I have dialed down to where the issue is. It’s my female adapter that attached to the cylinder.

What happened is, all of a sudden I noticed it was struggling to vacuum the air and creating pressure, but the dial on the gauge would shoot it as if it was creating a lot of pressure. It would go up to “20InHg” and I would barely have any pressure in the cylinder. Maybe 1.5 InHg.

To make sure it was the female I tried my other cylinder and it works just fine. So what’s the problem?

I have a tendency to not clean my tube right away because I use coconut oil and it never seems to be much of a build up or another. It normally just hardens up and then when heated is helpful lube all over again. So I wonder if maybe coconut oil built up where the actual hole or area is that sucks in the air.

Has anyone else ever had this problem or know what to do? I tried cleaning it well with really hot water which normally does the trick for coconut oil because it just melts and goes away but I still have this issue after doing that. Luckily I have another tube I can use or else I’d be really bummed right now.

I was able to recreate the problem when the male fitting was not completely inserted into the female. Make sure the male fitting is getting clicked in when you insert it.

You can also exercise the female connector by alternating pressing the 2 buttons on it to make sure it is clicking into place properly.

Appreciate the help Gprent, that must have been the case. It working properly now. What is weird is during when this was happening I checked to make sure it was in and it still acted the same way, so i dont know at this point maybe I was mistaken. Who knows. Either way I’m glad I have two cylinders just in case something happens to the other. Thanks again my man.

Another common way this is replicated is with a kink in the tubing or otherwise limiting the pressurized area to just the tubing like with a clog.

If either fitting were damaged or malformed it would cause similar if a blockage resulted. New fittings are cheap plastic affairs that usually last forever if it happens again.

I use a lot of lubricant when I pump and it’s very common for some of it to leave the cylinder and enter the quick disconnect of the tubing. This can make the vacuum readings and even the vacuum itself erratic. I will also hear a tiny gurgling sound as I pump. When this happens, I disconnect the tubing from the cylinder, pull of the end connected to the pump, and I I blow onto that end with the quick connect end into a paper towel. This allows me to clear the line quickly and my pump has been just fine. I think if I didn’t clear the line, I’d be on my second or third pump.

I don’t know if this is applicable to your particular problem, but it might not hurt to see if there isn’t anything blocking the line.
