Quick 90° turns for 12 mm OD hardline
This Barrow Mods rotary coupling lets builders route rigid tubing at right angles without bending or stressing the tube. The G1/4″ thread connects directly to standard water-cooling blocks and radiators. It is designed for custom-loop builders who need clean, leak-free corners in a hardline build.
G1/4″ thread and 12 mm OD clamp
The single spec that decides fitment is the combination of a standard G1/4″ male thread and a 12 mm outer-diameter compression seat. Only 12 mm OD rigid tubing seats correctly; soft tubing or any other hardline size will not seal.
Handles one 90° bend per fitting
Each adapter manages a single 90 degree change of direction in a 12 mm hardline run. Multiple units can be chained for complex routes, but every additional joint adds a potential leak point and flow restriction. Builders needing tighter radii or softer tubing must choose a different fitting type.

Questions about this item
How does the 90° angle work inside a finished loop?
The rotary joint lets you make a sharp 90° turn in rigid tubing without bending the tube, so the run stays straight until the fitting itself changes direction.
What does the G1/4" thread connect to in practice?
The standard G1/4" thread screws directly into any water-block, radiator, pump or reservoir port that uses the same thread, giving a universal connection point.
What tubing size and type must I have for this fitting to seal?
It only accepts 12 mm OD rigid hardline tubing; soft tubing or any other diameter will not seal or lock in place.
