EK-HDC ALU Fitting is a high-flow compression fitting designed for use with only solid tubing. The choice of material for the tube can be aluminum or any other non-metal based material like Acrylic, PETG, glass etc..

EK-HDC Fitting is a fail-safe tubing fitting connector as the locking ring prevents the solid tube to be pulled out of the socket. The base of the fitting contains one O-ring while the other O-ring is compressed by the locking ring, thus securing the hard tubing.

The base and locking ring are made of high-grade CNC machined aluminum and the fitting features a quality rubber O-ring. The locking ring has a flawless and even coloring with a process called anodization. The EK-ACF ALU fitting is fully compatible with EK-AF ALU series 45° and 90° angled adapters.

Best practice is to install these fittings using Allen Key 9mm (not included, available for separate purchase).

  • It is mandatory to chamfer (deburr) the edges of freshly cut solid tube in order to prevent gasket (o-ring) damage. EK recommends a 0.5mm x 45° chamfer.
