So you've built yourself a Puck or other box mod and you're using a 901 atty. After a week or two you notice juice running down the sides of your box or even inside your Puck. Even though we try not to overfill, we always do. juice will find it's way out one way or another.
I started getting leaking when I built my Puck Cruiser. A Puck with a Pump Bottle with the pump bottle inspired by capecodjim. This pump is the best thing that ever happened to PV use but I noticed leaking at the bottom of the atomizer every now and then, running down around the box. I tried to make the atty as tight as possible but still would get leaks.
I found a solution that works so well, I never get a leak now. Assuming you have a sealed connector (if you don't, seal it with solder, glue or other), it is so simple anyone can do this and the cost is next to nothing. What is it?... A simple rubber o-ring. Yep, a simple rubber o-ring around the threads of the 901 atty connector. When you screw on the atty, it compresses the o-ring and seals the connection between the atty and the connector. No more leaks!
When you are screwing on your 901 atty, you have to push down a bit to get it started but once you start screwing it on, it starts to compress the o-ring, sealing it all up. No more juice can leak out the threads of your atty/connector connection. This may have been done before, but if it has so be it. It works so well it's worth mentioning again if it had been mentioned.
Here are some photos of the o-rings I used and the o-ring in action...
There are the o-rings I used, bought from a hardware store in the plumbing section.
Here is the o-ring as it is fit onto the 901 atty connector.
And once your screw on the atty, it looks like this...
No more leaks
