Koppelborgring EK Water Blocks EK-Quantum Torque Colour Ring 10-pack STC 12/16

The EK-Quantum Torque Color Ring 10-Pack STC 12/16 is a set of anodized aluminum torque fixing rings designed for use with EK-Quantum Torque STC 12/16 soft-tube compression fittings. Supplied as a pack of ten, these color rings are intended to be fitted onto 12/16mm soft tubing setups to provide a secure interface with the compression fitting while adding a consistent visual accent. Manufactured in Slovenia, the rings match EK's minimalistic fitting line and are sized to work specifically with 12/16 ID/OD soft tubing applications.

Advantages

The anodized aluminum construction offers corrosion resistance and a durable surface finish that maintains appearance over time. Supplied in a 10-pack, these rings simplify multiple-connection builds and ensure color consistency across a system. Their design allows straightforward installation onto compatible EK-Quantum Torque STC 12/16 fittings and they are manufactured to fit precisely, reducing the risk of misalignment or uneven compression. The rings are available in various colors to support coordinated aesthetics in liquid cooling loops.

Suitable for

• Custom PC liquid cooling loops using 12/16mm soft tubing
• Builds that require matched visual accents across multiple fittings
• Replacement or upgrade of existing compatible compression fittings

How to use

Before assembly, verify compatibility with EK-Quantum Torque STC 12/16 fittings and ensure tubing is cut square and free of debris. Screw each color ring onto the fitting body prior to installing the compression locking ring, positioning it to provide the desired visual accent. Tighten fittings following the manufacturer's recommended torque and procedural guidance, using a 1/4" hex key where applicable. Inspect each connection after assembly to confirm correct seating and even compression of the soft tubing.

Recommendations

Use these rings only with EK-Quantum Torque STC 12/16 fittings and 12/16mm soft tubing to ensure proper fit and sealing. Match ring colors across fittings in the same loop for consistent appearance and replace any ring that shows visible damage or gouging before reusing.
