10 mm hose fitting made of nickel-plated brass with O-ring for PVC, PU, PA, silicone, or PE hoses with a 10 mm inner diameter. G1/4" external thread. Height 35.5 mm. Straight thread, SW 14. Note for water cooling beginners: The connections for imperial hoses (7/16", 3/8", ½") are labeled in the shop with a mm specification. This may vary by ±1 mm, which is not an issue since a hose clamp is required for installation. If you want to install the hose without a hose clamp, you should choose a larger connection. For some connections that tend to deviate upwards, it may also be possible for a 13 mm connection to seal on a hose with a 13 mm inner diameter even without a hose clamp. Overview: 10 mm (3/8") hose clamp: none up to 8 mm, required from 10 mm; 10 mm (7/16") hose clamp: none up to 8 mm, required from 10 mm; 12 mm (1/2") hose clamp: none up to 11 mm, required from 12 mm; 13 mm (1/2") hose clamp: none up to 11 mm, required from 13 mm.
