## Summary description

Made in Slovenia.

## Long description

EK Water Blocks EK-Quantum Torque HDC 16 Silver is a single silver torque wrench end fitting with a 1/4" imperial hex interface. It is designed to adapt torque wrenches for use with HDC 16 hard-tube compression fittings, providing controlled tightening of valves, fittings and compression parts in water-cooling and PC assembly. The fitting matches EK-Quantum HDC 16 compression hardware for solid tubing such as acrylic and PETG and features a minimalist appearance with an interchangeable aesthetic ring option (ring sold separately).
Advantages
The adapter delivers a precise 1/4" hex interface for repeatable torque application when fitting HDC 16 compression components. Its silver finish complements EK-Quantum series products and the non-branded, low-profile design maintains a clean system look. Grooved surfaces on the fitting improve manual handling during initial placement, while the construction supports secure compression of the tubing via the compression ring that compresses the gasket to lock the tube in place.
Suitable for
Installation and controlled tightening of HDC 16 hard-tube compression fittings
Assembly and maintenance of custom water-cooling loops using acrylic or PETG tubing
Precise torque application to valves, fittings and compression parts in PC builds
Key specifications
Material finish: silver
Drive interface: 1/4" imperial hex
Compatibility: HDC 16 hard-tube compression fittings for solid tubing
Intended tubing: designed for acrylic and PETG hard tubing
Design: minimalist, no visible branding; supports interchangeable aesthetic ring (sold separately)
How to use
Thread the adapter onto the HDC 16 compression fitting according to the fitting manufacturer’s instructions until hand-tight. Attach a torque wrench with a 1/4" hex drive to the adapter and apply the specified torque for the fitting or component being secured. When installing solid tubing, ensure the compression ring compresses the rubber gasket fully so the tube is locked in place and cannot be pulled out. If using an aesthetic ring, install it before the compression locking ring as required by the fitting design.
Usage recommendations
Use a calibrated torque wrench and follow the torque specifications supplied for HDC 16 fittings and other water-cooling components. Avoid over-tightening; hand-tighten first and then apply the correct torque value. Inspect the gasket and compression ring periodically and replace any worn sealing elements to maintain a reliable, leak-free connection.
