About this Straight Adapter
A straight fitting joins two duct or hose ends in line. Set both ends the same and it is a coupler that joins two pipes. Set them different and it is a reducer that steps one size up or down.
The inside walls are smooth, so the air keeps moving and you lose less pull at the joint. Each end is printed to the standard size you pick, so it pushes on and holds in most setups.
