## Summary description

Fitting from ek water blocks, model 3831109893111, made of brass with a black finish. Compact component with a height of 33 mm designed for custom liquid cooling loops in PCs. Used to connect tubing or components securely, it provides corrosion-resistant metal construction and a neat appearance while ensuring reliable coolant flow and seal.

## Long description

EK-Quantum Torque Double Rotary Offset 21 - Black is a compact, premium brass adapter (height 33 mm) designed for custom PC liquid cooling loops. It combines a male and female G1/4" threaded connection with two independently rotating joints and provides a 21 mm offset to align tubing with distribution plate ports on CPU and GPU water blocks. The fitting uses CNC-machined brass with a satin black finish and is sealed with NBR O-rings; its design matches the EK-Quantum Torque family and replaces several separate parts by combining offset and rotary functions in one component.
Advantages
The double rotary design allows both offsetting and angular adjustment through two rotating joints plus a central rotating element, offering tactile clicks every 45 degrees for straightforward positioning while still allowing continuous stops at any angle. Machined brass construction and quality NBR O-rings ensure corrosion resistance and a reliable seal. The fitting can be tightened from the top with a hex key when knurling is not accessible, and visually complements other EK-Quantum Torque fittings.
Suitable for
 Aligning hard tubing from GPU or CPU water blocks to distribution plates
 Offsetting parallel or perpendicular tube runs in custom loops
 Replacing multiple adapters (rotary 45°, rotary 90°, and 7 MF extender) with one component

How to use
Install the fitting by threading the male or female G1/4" ends into the corresponding ports on water blocks or distribution plates. Rotate the two joints and the central rotating element to set the required offset and angle; the mechanism provides 45-degree tactile detents but can be set at any intermediate angle if needed. If the knurled surface is inaccessible, use a hex key from the top to tighten the fitting securely. Verify O-ring seating and ensure connections are hand-tightened and then appropriately secured to avoid leaks.
Usage recommendations
Use this fitting when precise alignment of hard tubing to a distro plate is required, especially with EK Vector² GPU and compatible CPU water blocks following the EK-Matrix7 standard. Check compatibility with your loop components and avoid over-tightening to protect threads and O-rings.
