The 6-pack EK-HDC Fitting is a hard tube compression fitting pack, they are designed for use with solid tubing such as Acrylic, PETG, Copper, Stainless Steel, Glass, Carbon Fiber or any other type of compatible hard tube.
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 and the ring are made of black nickel-plated CNC machined brass with quality O-rings. These fittings are fully compatible with EK-AF series (45°/90°) angled adapters.
Best practice is to install these fittings using Allen Key 9mm (not included, available for separate purchase).
