EK-Quantum Torque 6-Pack HDC 12 is a fitting multipack containing six EK-Torque HDC fittings. These are EK's premium 12mm hard-tube compression fittings designed for use with solid tubing such as Acrylic and PETG. With a non-intrusive, yet striking look, and with NO added branding at all. They can be complemented by interchangeable aesthetic color rings, and are an ideal choice for anyone and a perfect match with EK-Quantum series products. To make sure they are undamaged in transport, they are packed in a box cushioned in black foam.

The locking ring prevents the solid tube from being pulled out of the fitting by compressing the rubber gasket underneath the ring. The grooves on the outside allow for easier hand tightening. The compression ring has cutouts in the EK Quantum signature shape allowing for the colored aesthetic ring to be shown. The colored rings are available in many colors and are screwed onto the fitting before the compression locking ring. The aesthetic rings are sold separately.

The fitting barb and the compression rings are covered with a unique, high-quality nickel finish. Both are made of CNC machined brass and the seal is made quality rubber O-rings. 

The base fitting surface is smooth and has no adequate gripping surface, but the inside of the barb is socketed with a 9mm hex Allen key pattern. It's highly recommended to use an Allen Key 9mm (purchased separately) to prevent skin damage to the fingertips while installing the fitting. Please, be advised not to use excessive force when attaching fitting barbs using Allen Key 9mm in order to prevent damage to other liquid cooling products! We recommend using the EK-Loop Multi Allen Key (6mm, 8mm, 9mm) which is made to break if excessive force is used, thus preventing damage to more costly components of your loop.

These fittings are guaranteed to be compatible with all other EK Water Blocks liquid cooling products.
