I have been using pet store fish tank tees and wyes in the plumbing on my boat and I do prefer clear tygon tubing because I can see what's happening inside. I did some testing and found that the tubing (any tubing) can slip off those plastic fittings with a slight tug and if it had a spring clamp ...off with a little stronger pull. I started to replace every thing in the boat with these brass fittings with bead ends. I silver braised two pieces of brass tube to make the Tee and soft soldered a 1/8 piece of the next larger size tube on the ends for the bead. For a clamp I just use a very small ty- wrap or zip tie. My inspiration was the Polaris pool sweep in my pool which used something similar. The tube now WILL NOT come off the end of of the tube.

Good plan, Bob!
The 1/8" airhose used in the SubDrivers use straight tube, but once the hose is on there, and particularly if you're using the white or gray variety, they're exceptionally hard to get off again without prying or cutting. Kind of like those Chinese fingers we all played with at one time or another. They compress more the more you pull on them!

Correct. I always remember the old saying- a chain breaks at its weakest link. Never had any issues with tubing on plastic fittings personally, too low of a pressure to be any problem, but each to their own.DIVE IN! Go on, go on, go on, go on, GO ON! http://www.diveintomodelsubmarines.co.uk

I use silicone tubing. Seems to last forever, doesn't perish, and maintains a good seal. Easy availability on ebay etc.DIVE IN! Go on, go on, go on, go on, GO ON! http://www.diveintomodelsubmarines.co.uk

Yes-blue/green silicon-actually I use it inside the dry containment housing the above mentioned pumps all of about 2.5 inches times 4 from the pumps to the thru "hull" nipple ..it is kind of friendly to a sharpie labeling which one is which. I use the tygon also for dry running of wires and full length antenna housing...nice to be able to see any water incursion.
