CDL 3/16 tubing kinking with double barb tee?

[DrTimPerkins]

For some reason I have a much harder time when making drops vs putting the t into the 3/16 mainline.

To help with terminology, the 3/16" "mainline" you refer to is actually the "lateral line".

Progression is: spout to dropline to tee into lateral line though saddle into mainline (if mainline is being used).

Just an update in case anyone is having trouble getting cdl 3/16 tubing fittings to go in. Using a little bit of water to wet the T barb fitting worked very well with 2 handed tool! It was almost impossible to get the T barb on when it was dry and now I am putting my drops together with almost no difficulty.

Thanks for the help everyone

- side note, I highly recommend cdl 3/16 barb/tubing. Had a few trees drop lines right to the ground during recent strong wind storm and everything stayed together perfectly.
