Install "Big-Tube Slimline Tee-Nozzles" directly on BIG TUBE 3/8" tubing. (standard tubing is 1/4")
This is a really fast and easy way to install slimline nozzles in long runs (without as many circuit considerations as with standard 1/4" tubing.) Fewer connections means your installation time is reduced significantly.
Used ONLY with non-standard 3/8" tubing. Excellent choice for large and commercial installations.
