## Summary description

The EK Water Blocks EK-Quantum Torque Compression Ring 6-Pack HDC 16 is designed for secure and leak-free connections in liquid cooling systems. Made from durable brass with a nickel finish, these compression rings ensure a reliable seal and enhance the aesthetic of your build. Each pack contains six rings, perfect for multiple fittings or replacements.

## Long description

The EK-Quantum Torque Compression Ring 6-Pack HDC 16 (Nickel) is a set of six CNC-machined brass locking rings with a nickel finish, designed specifically for use with EK-Quantum Torque HDC 16 series fittings. These rings are not stand-alone fittings and must be used together with an existing Torque fitting barb and the optional aesthetic colored ring. The compression ring secures a solid tube by compressing the rubber gasket beneath it, preventing the tube from being pulled out while exposing the decorative colored ring through signature cutouts.
Advantages
The compression rings are made from precision-machined brass and plated with a durable nickel coating for corrosion resistance and consistent appearance. Grooved outer surfaces provide improved grip for hand tightening. The design includes EK Quantum–style cutouts that reveal an aesthetic ring (sold separately), allowing both secure mechanical connection and customizable visuals. Sold in a six-piece pack suitable for multiple fittings or replacements.
Suitable for
EK-Quantum Torque HDC 16 series fittings (16 mm)
Securing solid tubing in custom liquid cooling loops
Users needing multiple spare or replacement compression rings
Key specifications
Material: CNC-machined brass
Finish: Nickel plating
Compatibility: Only with EK-Quantum Torque HDC 16 fittings
Pack quantity: 6 compression rings
Requires: Existing Torque fitting barb and rubber gasket (fitting not included)
How to use
Install the aesthetic colored ring onto the Torque fitting first if desired (sold separately). Slide the rubber gasket onto the fitting barb, push the solid tube onto the barb, then place the compression ring over the tube and hand-tighten until the ring compresses the gasket and secures the tube. Use the grooved outer surface to improve grip during manual tightening. Do not use the compression ring as a standalone connector; it must be paired with the compatible Torque fitting barb.
Usage recommendations
Ensure compatibility with EK-Quantum Torque HDC 16 fittings before purchase. Inspect rubber gaskets for wear and replace them if necessary to maintain a reliable seal. Tighten by hand to avoid damaging threads or deforming the tube; check fittings for leaks after initial system fill.
