Barrow Multi-Link Adapter TWT90KND-K14 b 90° G1/4 AG to 14mm AD Hardtube Rotatable Black

Barrow Multi-Link Adapter TWT90KND-K14 b 90° G1/4 AG to 14mm AD Hardtube Rotatable Black is a 90-degree rotatable fitting designed for custom liquid-cooling loops. It connects a G1/4 male (external) thread to a hardline with 14 mm outer diameter, providing a compact angled interface that simplifies tubing routing and alignment inside PC cases and cooling assemblies.

Advantages

The rotatable 90° design allows precise orientation of the hardtube connection without rotating the whole fitting in the threaded port, enabling neater runs and reduced stress on joints. The adapter is finished in black for a discrete appearance and is compatible with standard G1/4 threaded ports used in water blocks, radiators and pumps. Its hardtube interface is sized for 14 mm outer-diameter tubing, offering a secure mechanical fit for hardline connections.

Suitable for

• Custom liquid-cooling PC builds requiring angled hardtube connections
• Compact or cramped case layouts where tubing must turn sharply
• Maintenance or modification of existing cooling loops to improve routing
• Connections between water blocks, radiators, reservoirs and pumps with G1/4 ports

Key specifications

• Connection type: G1/4 male (external thread) to 14 mm outer-diameter hardtube
• Angle: 90-degree rotatable joint
• Finish: black
• Application: hardline (rigid) tubing for liquid-cooling systems

How to use

Install the adapter by screwing the G1/4 male thread into a compatible G1/4 female port until hand-tight, then secure with a wrench if required, taking care not to overtighten. Insert and secure the 14 mm outer-diameter hardtube into the hardline interface according to the tube fitting method used in your loop (compression collar, O-ring seat or compatible clamping mechanism as appropriate). Rotate the adapter to the desired orientation before final tightening to obtain the correct tubing direction and minimize strain on connections.

Recommendations

Verify compatibility with your tubing and system components before installation. Use appropriate sealing practices (thread sealant tape or approved thread sealant for G1/4 connections where required) and avoid excessive torque to prevent damage to threads or fittings. Periodically inspect joints for leaks after system fill and during initial operation.
