EK-HDC Fittings (Hard Tube Compression Fitting) are 16mm hard-tube compression fittings designed for use with rigid tubing like acrylic, PETG, Aluminum. With a high-quality finish, the EK-HDC Fittings are an aesthetically appealing and secure option for your cooling loop. EK-HDC Fitting is a secure fitting as the locking ring prevents the hard tube from being pulled out of the fitting by compressing the rubber gasket underneath the ring. The barb and compression ring are made of CNC machined high-grade aluminum and feature quality O-rings. These fittings sport a low-profile design hence it is recommended to handle the fitting barb using Allen Key 9mm.
