LOL...Here are a few photos of some lockline.
Attachment:
(1) 3/4 lockline tubing with 5/8 straight nozzle on the end and 1 link I seperated from the lockline tubing. I bent the links as much as I could with just 5 links.
(2) This is a male adaptor and a threaded bulkhead which shows how the adaptor can be used in a bulkhead if you drill through our tank
(3) This is a picture of a manifold I made for my return on my new cube which is all PVC and at the end, I used a female elbow, threaded in the male lockline aadaptor, added 5 lockline links, a 3/4 to 1/2 inch lockline reducer, and a 1/2 inch flared nozzle. I checked for you to see if the lockline was leaking at all at any of the links and it was all dry. Also, I don't have any microbubbles at all in the tank with the lockline exposed so I guess it doesn't always happen. I personally still would not use it anywhere but over the tanks surface and submerged as much as possible.
(4) This is a side shot of my cube showing the threaded bulkheads with the lockline valves to control the flow, the lockline tubing and nozzles on the end.
(5) Forgot this one
This is a male adaptor which you can use to thread into a female pvc adaptor on one side (or a bulkhead like the 2nd pic) and the other end goes into the other lockline pieces
Hope I was able to help you some
