Phobya 13mm (1/2") Fitting G1/4 with O-Ring (FatBoy) - Black Nickel

Robust  high-quality black 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 11-13mm. 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.
