Review on 🔧 Enhance Your Brewing Setup with CellarBrew Splicer Stainless Reducing Fitting by Aaron Franklin

This is a poor quality, tight tolerance fitting and will not fit high tolerance lines such as nylon or rubber fuel lines (see photos). the inside of the line and cause a restriction or flow problem. I needed this for a nylon fuel injector line and the tolerance is so far out that the 5/16 side of the gear fits the 3/8 nylon line - the 5/16 side doesn't even try to fit. When I used the heat gun to put it on, it ripped the 5/16 line to apply pressure.
