Barrow Multi-Link Adapter 90° G1/4, model TWT90KND-K12 b for 12mm hard tubing

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.

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.
