## Summary description

The EK Water Blocks 3831109849781 is a brass fitting designed for computer cooling systems. With a height of 15mm and a diameter of 2cm, it offers a durable and stylish solution for your cooling needs. The gold color adds an aesthetic touch while ensuring reliable performance.

## Long description

EK-Quantum Torque HDC 12 fittings are minimalistic 12 mm hard-tube compression fittings for solid tubing such as acrylic and PETG. The fitting body is CNC-machined from brass, nickel-plated and finished with genuine gold plating; seals are rubber O-rings. This particular variant is a compact brass fitting with a total height of 15 mm and an outer diameter of approximately 20 mm, intended for use in PC liquid cooling loops and is compatible with the EK-Quantum Torque family of adapters, extenders and accessories.
Advantages
The design offers a low-profile, non-branded appearance with interchangeable aesthetic color rings (sold separately). The locking/compression ring secures solid tubing by compressing an internal rubber gasket, while external grooves make hand tightening easier. The barb and compression components are precision machined from brass and plated for corrosion resistance and visual consistency. A 9 mm hex socket is integrated into the barb to allow tightening with an Allen key, reducing risk of fingertip injury compared with direct hand force.
Suitable for
12 mm hard tubing installations using acrylic or PETG tubing
PC custom liquid cooling loops requiring compact, low-profile fittings
Systems where aesthetic matching with EK-Quantum Torque components is desired

How to use
Slide the aesthetic ring (if used) onto the fitting and screw it on before fitting the compression locking ring. Insert the cut-to-length 12 mm hard tubing (acrylic or PETG) into the fitting until it seats against the barb. Screw the compression locking ring down to compress the internal rubber gasket and secure the tube. Use a 9 mm Allen key in the barb’s internal hex socket to hold or tighten the fitting where necessary; avoid using excessive torque to prevent damage to nearby components.
Usage recommendations
Use a proper 9 mm Allen key (sold separately) to tighten or hold the fitting during installation to protect fingertips and to avoid over-torquing. Do not use the fitting on soft or flexible tubing types intended for soft compression fittings. Aesthetic rings are sold separately and should be installed before the compression ring.
