13mm (1/2") barbed fitting G1/4 with O-Ring (Perfect Seal)

The perfect seal fittings ensure, as the name implies, a perfect seal with 1/2" hoses (approx. 13mm inner diameter). A hose clamp is usually not required, as the fitting has a large outer diameter.

Technical specifications:
Thread size: G1/4
Thread length: 6mm
Compatible with hoses with an inner diameter of 13mm (1/2")
Fitting inner diameter: 10mm
Upper fitting outer ring: 15.8mm
Middle hose contact surface: 14.3mm
Key width: 16mm

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.
