## Long description

Spare O-ring set for EK Water Blocks EK-Quantum Torque HDC 14 and EK-Classic HDC 14 fittings. This package contains six black rubber O-rings sized for hard tube compression fittings with a 14 mm outer diameter. The gaskets are manufactured from NBR70 material to provide reliable sealing performance in liquid CPU and GPU cooling loops, intended for maintenance, replacement of worn seals, or when assembling HDC fittings to ensure proper compression and alignment.
Advantages
These O-rings offer a precise fit for HDC 14 hard tube compression fittings, reducing the risk of leaks when installed correctly. Made from NBR70, the material balances flexibility and resistance to common coolant formulations used in PC water cooling. The pack of six allows multiple replacements or servicing of several fittings without immediate need to reorder, and the black color blends unobtrusively with typical loop components.
Suitable for
 Maintenance and replacement of worn seals in PC water-cooling loops
 Assembly of EK-Quantum Torque HDC 14 compression fittings
 Assembly of EK-Classic HDC 14 compression fittings
 Repairing minor leaks at hard tube compression connections
Key specifications
 Quantity: 6 pieces per package
 Material: NBR70 (nitrile rubber)
 Cross-section / profile: OR 14,1 x 1,6 mm (inner/section specification for HDC 14 fittings)
 Color: black
 Designed for: hard tube compression fittings with 14 mm outer diameter
How to use
Before installation, inspect each O-ring for damage or deformities. Clean the fitting and tubing contact surfaces to remove debris and old residue. Place the O-ring into the designated groove of the compression fitting, ensuring it sits evenly without twists. Assemble the fitting according to manufacturer instructions, applying even torque to achieve compression without over-tightening. After assembly, perform a leak test by filling the loop and observing fittings under pressure or during a short run to confirm proper sealing.
Usage recommendations
Replace O-rings during planned maintenance intervals or whenever fittings are disassembled. Avoid stretching O-rings excessively during installation and do not use incompatible lubricants or solvents that can degrade NBR70. Keep spare O-rings in a cool, dry place away from direct sunlight to maintain material properties.
