Aquatuning 13mm (1/2') fitting G3/8 with O-Ring (High-Flow)

High-flow barbed fitting for hoses with an inner diameter of 11mm to 13mm. This fitting was specially designed for High-flow systems. Technical data: Thread: 3/8" Compatible to hoses with an inner diameter of 11mm to 13mm Note for watercooling beginners : The connectors for imperial hoses(7/16", 3/8", ½") are provided with measurements in mm in our shop. These can differ by +-1mm, which is no problem as hose clamps have to be used for installation. If the hose is to be mounted without a clamp, a larger fitting should be chosen. With some fittings that tend to be larger, it is possible though that a hose with an inner diameter of 13mm actually does seal without a hose clamp.
