5/3mm OD Compression Fittings
Alphacool ES compression fittings for 5/3mm soft tube, the size that comes with the Alphacool MCX distributor, in straight and 90 degree rotatable G1/4 versions. For the main loop we recommend 16/10mm (3/8" x 5/8") soft tube: the most flexible common size and the least prone to kinking.
