Meet the new DIY Cold Plunge Venturi Injector (for ozone sanitation). I have tested several different plumbing fittings in my cold plunge filtration & sanitation system build and this one is hands down the best.

This venturi fitting is easier to use and can be attached to both flexible spa hose and vinyl tubing. It also eliminates 2 threaded fittings altogether, which tend to leak to the inexperienced user. Check out the suction test and let me know what questions you have!
