## Long description

Barrow Multi-Link adapter TWT90KND-K12 b is a 90° angled G1/4 fitting engineered for use with 12 mm hard tubing. It provides a compact right-angle connection for liquid cooling loops and custom water-cooling assemblies, enabling neat tube routing and reducing mechanical stress on adjacent fittings. The adapter is intended for G1/4 threaded systems and is suitable for tight spaces where a clean 90-degree turn is required.
Advantages
The adapter offers a low-profile 90° connection that preserves coolant flow while minimizing the space needed for tubing turns. Its compatibility with 12 mm hard tubing ensures a secure, leak-resistant joint when used with appropriately sized tubing and proper installation. The design reduces bending pressure on the tubing and adjacent connectors, helping maintain long-term stability of the cooling loop.
Suitable for
 Custom PC liquid cooling loops requiring a compact 90° turn
 Tidying hard tubing runs in small or densely packed cases
 G1/4 threaded components in water-cooling builds
 Retrofit or replacement of existing angled fittings for 12 mm hard tubing
Key specifications
 Thread type: G1/4 compatible
 Angle: 90 degrees for right-angle connection
 Designed tubing outer diameter: 12 mm hard tubing
 Application: liquid cooling and general G1/4 threaded assemblies
 Form factor: compact, low-profile multi-link adapter
How to use
Install the adapter by threading it into a compatible G1/4 port and secure it to the corresponding component. Prepare 12 mm hard tubing by cutting square and deburring the ends, then fit the tube to the adapter following the manufacturer’s recommended mounting method for hard tubing (compression fitting, clamp, or compatible sealing method as applicable). Tighten threaded connections to the appropriate torque to prevent leaks while avoiding over-tightening that could damage threads or fittings. Verify alignment and ensure the tubing sits correctly in the adapter before filling the loop.
Usage recommendations
Use with properly sized 12 mm hard tubing and compatible G1/4 components. Confirm thread engagement and perform a leak test after installation. Avoid excessive bending or mechanical force on the fitted tubing to maintain seal integrity and long-term reliability.
