EK-HDC Fitting is a more secure variant of the EK-HD Adapter fitting as it prevents solid tube to be pulled out of the fitting by compressing the rubber gasket underneath the ring.
The barb is made of nickel-plated CNC machined brass while the ring is made of anodized CNC machined aluminum and feature quality O-rings. These fittings are fully compatible with EK-AF series (45°/90°) angled adapters.
