The Barrow G1/4" Thread 45-Degree Dual Rotary Fitting Adapter allows you to extend your fitting port at a 45 degree angle, allowing larger fittings to be used or allowing connection of other fittings!A great solution for people not using tubing between very close blocks!These have two rotary connections allowing the adapter to spin 360 degrees in two locations.This keeps tubing from kinking or breaking.
