What's the difference in a cap being threaded or "clicking"? Is one better than the other?

The cap is threaded like a bolt. It screws into the the fuel receiving end of the fill tube. The cap is designed so that when it is screwed in and tightened, once it attains the required snugness, the cap will "click and slip", not allowing further over tightening. When the cap wears, the snugness required for the cap to tighten to a proper seal before it begins to "click", wears to a point where the cap will click and slip before it tightens securely. This causes the cap to be slightly loose and allows air into the tank along with vapor escape affecting the fuel/air mixture. The result is the automobile service light will come on and light up.

Hello Kathleen, I had the same frustration for a few minutes until I accidentally squeezed the cap and, "Pop!" It opened. Now, I realized that the design is clever to prevent accidental opening from pulling on the cap.Hope that helps.

They're necessary if you can access the screw head with a screwdriver. I ran the lock through one of the cable ends, so a cap wouldn't fit if i wanted it to.

The first time I used it the cap screwed in about half way. But, there was only a few drips and i did not want to dammage the threads by over tighting. Now after severell drains and fill ups it screws down better.

They do have a model with a cap, but I find it hard to take off, so I prefer the click-type pen. It's a great pen, either way.

There is no difference between the purple cap and the white one. I have used both with no issues.

Mine twisted. They make tops that pop on too. I think those are better. Mine leaks if not screwed on properly.

It snaps tight and has never opened on me. Now I've noticed that some click closed easier than others, so you'd need to be certain it clicked shut, but they've all been very reliable as far as leaking. The only issue I've ever had is if I don't screw the cap on tight enough, it dribbles but that's on me.

The top cap is a separate piece and larger in diameter than the stem mount dia. This means you can't take the stem off the top!! Just a mention as I didn't think of that. Not a huge issue, but something to be aware of

These are not screw on lids, they are more pressure locks. When screwing on just tighten slowly until you feel it getting snug, you'll feel the lid snap or click to a position. That's as far as you need to tighten, the seal will do the rest of the work.

It is very proprietary in that it is a snap and click mechanism, there are no threads. The id of the head is about 7/8" and the od is about 1 1/16", the depth is about 2 1/2". Hope this helps.

They ars all screw in. The caps are screwed on. I've always just pushed on my driplines and never had one come off. In fact, if I ever need to disconnect a line, I usually have to slit it so it will let go.

The switch is under that cap, but it doesn't screw off. It just kind of pops off. It's just a water protection and isn't an annoyance at all.

It seems to snap in to the cap very securely. I haven't had any issues with that.
