10mm barb fitting made from nickel-coated brass for PVC, PU, PA, silicone or PE hoses with an inner diameter of 11-13 mm. G3 / 8 "outer thread Inner diameter of connector. 8.4 mm

Note for watercooling beginners:
The connectors for imperial hoses (7 / 16 ", 3 / 8 ", œ ") 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 chosen, a larger fitting should be. With some fittings that tend to be larger, though it is possible that a hose with an inner diameter of 13mm actually does seal without a hose clamp.
