## Summary description

The EK Water Blocks 3831109849989 fitting is designed for computer cooling systems. Made from durable brass with a gold finish, it measures 11.5mm in height and 1.6cm in diameter. This fitting ensures reliable connections and optimal performance in your cooling setup.

## Long description

EK-Quantum Torque Micro HDC 12 - Gold is a compact 12 mm fitting for solid tubing including acrylic, PETG, and brass tubes. With an installed height of 11.5 mm and an outer diameter of 16 mm, this fitting provides a much smaller footprint than standard Torque HDC 12 fittings while ensuring secure, leak-resistant connections in tight spaces. The body is CNC-machined from brass, nickel-plated and finished with genuine gold.
Advantages
The Micro design reduces installed height by approximately 23% compared to standard Torque HDC 12 fittings and has a smaller outer diameter, allowing tube routing where regular fittings would be too large. A high-quality EPDM rubber gasket inside the compression ring grips the solid tube for a reliable seal. The inner barb is socketed with a 9 mm hex (Allen) pattern to facilitate tightening without damaging surrounding components.
Suitable for
Custom PC liquid cooling loops using solid tubing (acrylic, PETG, brass)
Installations with limited clearance where low-profile fittings are required
Aesthetic builds that require a gold finish and compact hardware

How to use
Slide the compression ring over the end of the solid tube, insert the tube fully onto the fitting barb, and tighten the compression ring until the EPDM gasket engages and secures the tube. Use a 9 mm Allen key to engage the inner socket if required to hold the fitting during installation. Ensure even tightening and avoid over-torquing to prevent damage to the tube or fitting finishes.
Usage recommendations
Use an EK-Loop Multi Allen Key or a properly sized 9 mm hex key to tighten the fitting and avoid damaging other liquid cooling components. Verify tube end faces are square and clean before installation; periodically inspect fittings for tightness and signs of wear.
