## Long description

EK-Quantum Torque Compression Ring 6-Pack HDC 16 - Black is a precision locking ring designed for use with EK-Quantum Torque HDC 16 series fittings. This product is not a standalone fitting and requires an existing Torque HDC 16 fitting with a barb to function. Each pack contains six CNC-machined aluminium compression rings finished in satin black and intended to secure soft or solid tubing by compressing the gasket beneath the ring.
Advantages
The compression ring prevents tubing from being pulled out of the fitting by compressing the rubber gasket underneath, providing a secure mechanical hold. External grooves on the ring improve grip for hand tightening, while signature cutouts expose the separately sold coloured aesthetic ring for a customised appearance. Machined aluminium construction with a satin black finish ensures durability and a consistent look. Compatible only with EK-Quantum Torque HDC 16mm fittings.
Suitable for
Securing 16 mm hard or soft tubing to EK-Quantum Torque HDC 16 fittings
Custom PC liquid cooling loops using Torque HDC 16 series fittings
Replacement or spare parts for EK-Quantum Torque HDC 16 installations
Key specifications

Model / MPN: 3831109836125
EAN: 3831109836125
Material: CNC-machined aluminium

How to use
Install the coloured aesthetic ring onto the Torque fitting first if desired (aesthetic rings sold separately). Slide the compression ring over the tubing and onto the fitting barb, then hand-tighten the ring until the rubber gasket beneath is compressed and the tube is held firmly. The external grooves allow improved grip during tightening. Verify the connection is secure before filling the loop and powering the system.
Usage recommendations
Use only with EK-Quantum Torque HDC 16mm fittings and compatible tubing. Do not overtighten; tighten by hand until the gasket is compressed and the tube is secure. Inspect fittings and rings during routine maintenance and replace any damaged components.
