Fitting for computer cooling system EK Water Blocks — brass satin steel/titanium finish Ø16 mm height 11.5 mm

EK-Quantum Torque Micro HDC 12 - Satin Titanium is a compact 12 mm compression fitting for solid tubing such as acrylic, PETG and brass. With an installed height of 11.5 mm and an overall outer diameter of 16 mm, this fitting reduces footprint compared to standard Torque HDC 12 fittings while retaining a metal construction and satin titanium finish. The fitting body is CNC-machined from brass and the compression ring uses a high-quality EPDM rubber gasket to securely grip solid tubes.

Advantages

The Micro form factor offers a 23% reduced height versus standard Torque HDC 12 fittings, enabling tube placement in tighter spaces. CNC-machined brass construction provides corrosion resistance and durability, while the satin titanium finish gives a neutral aesthetic. An internal 9 mm hex Allen key socket in the barb allows installation without relying on the external surface for torque, reducing risk of damage to adjacent components when using the recommended EK-Loop Multi Allen Key.

Suitable for

• Custom PC liquid cooling loops using 12 mm solid tubing (acrylic, PETG, brass)
• Installations with limited clearance where a low-profile fitting is required
• Builds requiring corrosion-resistant metal fittings with a satin finish

Key specifications

• Type: Compression fitting for solid tubing (HDC 12)
• Material: CNC-machined brass
• Finish: Satin titanium / satin steel appearance
• Outer diameter: 16 mm
• Installed height: 11.5 mm
• Tube size compatibility: 12 mm solid tubing (acrylic, PETG, brass)
• Seal: EPDM rubber gasket in compression ring

How to use

Slide the compression ring over the end of the solid tube, insert the tube fully into the fitting barb, and tighten the compression ring until the EPDM gasket secures the tube. Use a 9 mm hex (Allen) key in the internal socket of the barb for final tightening to avoid stressing the external surface. For best results, tighten progressively and check that the tube is firmly gripped without deforming the tube.

Recommendations

Use the EK-Loop Multi Allen Key or an appropriately sized 9 mm Allen key to avoid damaging nearby components. Verify compatibility with other EK Water Blocks components as this fitting is intended for EK liquid cooling systems and 12 mm solid tubing.
