OcUK 3/8" G1/4 - FatBoy Style - Shiny Silver - Barb Fitting @ £1.58 inc VAT
Robust high-quality nickel plated barbed fitting with cylindrical thread (G1/4"). The fitting is suitable for PVC, PU, PA, silicone and PE hoses with an inner diameter of 10mm. With integrated 1/4" Perbunan(r) O-Ring seal.
We recommend the use of hose clamps or zip ties for best possible safety!
Note for watercooling beginners:
The connectors for hoses(7/16", 3/8",1/2") 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.
Overview:
10mm (3/8") hose clamp: up to 8mm none, from 10mm up required
10mm (7/16") hose clamp: up to 8mm none, from 10mm up required
