Reducer Fittings
A reducer joins two different tube sizes in the same loop, which comes up when a component you want is only made for one size, or when you are reusing tube from a previous build.
Stocked here: Barrow 1/2" to 3/8" barbed reducers, in black and in silver.
Worth knowing before you plan around it: every reduction in a loop is a restriction, and restrictions cost head pressure. One reducer is fine. Building a loop that steps down and back up repeatedly is not.
Adapters that change thread rather than tube size are in fittings.
