EK-Quantum Torque HDC 16 fittings are EK's new minimalistic 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. 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.

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!

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