EK-Quantum Torque 6-Pack HDC 16 is a fitting multipack containing six EK-Quantum Torque HDC fittings. These are EK's premium 16mm 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. To make sure they are undamaged in transport, they are packed in a box cushioned in black foam.

The locking ring prevents solid tube to be 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 EKWB 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 satin silver finish. Both are made of CNC machined brass and the seal is made quality rubber O-rings. Satin Titanium EK-Quantum Torque series fittings are intentionally not painted on the inside to reduce the level of possible pollutants in the loop.

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.

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