Torque wrench end fitting 6-pack EK Water Blocks EK-Quantum Torque HDC 14 Silver (6 pcs)

EK Water Blocks EK-Quantum Torque HDC 14 Silver end fitting 6-pack contains six HDC 14-compatible torque wrench end fittings with a silver finish. Manufactured in Slovenia for use in custom PC liquid-cooling assemblies, these fittings are designed to attach to torque screwdriver heads to ensure a secure connection for hard-tube systems using acrylic or PETG tubing. Each fitting features a locking/compression ring that compresses a rubber gasket to prevent the solid tube from slipping, external grooves for easier hand tightening, and signature cutouts that expose interchangeable aesthetic color rings (color rings sold separately). Packaged in protective black foam to prevent damage in transport.

Advantages

The set provides six identical HDC 14-end fittings optimized for precise, repeatable tightening when used with a compatible torque driver, reducing the risk of overtightening or leaks. The silver finish delivers a neutral appearance that integrates with a variety of builds, while the compression locking ring and rubber gasket combination maintain a reliable mechanical and fluid seal for hard tubing installations. External grooves on the fittings allow for additional hand adjustment when needed, and compatibility with interchangeable color rings enables visual customization without altering functional performance.

Suitable for

• Custom PC liquid-cooling loops using 14 mm hard tubing (Acrylic / PETG)
• Assembly and maintenance tasks requiring torque-controlled fastening of fittings
• Modular builds where matching multiple identical fittings is required
• Applications needing corrosion-resistant, metal compression fittings with aesthetic options

How to use

Install the fitting onto the 14 mm hard tube by sliding the tube into the fitting until it contacts the internal seat, then screw down the compression locking ring to compress the rubber gasket and secure the tube. Fit the Torque HDC end onto the torque screwdriver head according to the torque driver manufacturer instructions and apply the specified torque to achieve a consistent seal without over-tightening. If using aesthetic color rings, screw the chosen ring onto the fitting before attaching the compression locking ring as designed. Verify the connection visually and perform a pressure or leak test on the loop before operating the system.

Usage recommendations

Use a compatible torque screwdriver and follow the torque settings recommended for HDC 14 fittings to avoid damaging tubing or gaskets; always perform a leak test after assembly and periodically inspect fittings and gaskets during maintenance.
