EK-HDC Fitting is a solid-tube compression fitting, designed for use with solid tubing such as Acrylic, Copper, Stainless Steel 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 is made of black nickel-plated CNC machined brass while the ring is made of black anodized CNC machined aluminum and feature quality O-rings. These fittings are fully compatible with EK-CSQ series (45°/90°) angled adapters.

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

Technical data:
– thread: G1/4″ BSP; 4.5mm male thread lenght
– supported tube: 12mm (OD)
– outer diameter of a fitting: 18.8mm
– installed height: 17mm
– compatible tubing: solid Acrylic-, Copper-, Brass- or Stainless Steel tube

ROHS Compliant!

Made in Slovenia – Europe!

– Please wet the gasket (o-ring) using drops of water prior to installing solid tube.
– Do not use excessive force when inserting solid tube!
– It is mandatory to chamfer the edges of freshly cut solid tube in order to prevent gasket (o-ring) damage. EK recommends a 0.5mm x 45° chamfer.

1 review for EK-HDC Fitting 12mm G1/4 – Black

  1. 5 out of 5

    Ordered a few of these a while back to match the ones I was given with some other watercooling equipment I purchased second-hand.

    Quality is top notch as expected from EK, tubes fit perfectly without any issues even at slight angles. No leaks, low profile, great look, and as an added bonus the black finish is somewhat rubberized making it easier to tighten/loosen the compression lock screws. What more could you ask for?
