## Long description

Barrow Multi-Link Adapter TWT90KND-K12 — 90° G1/4 female to 12mm hard tube, silver is a right-angle adapter designed for hardline liquid cooling systems. It converts a G1/4 female threaded port to a secure 12 mm hard tube connection, allowing a compact 90-degree turn in tubing runs. The silver finish offers a neutral metallic appearance suited to various build styles, while the adapter's geometry helps route hard tubing cleanly and reduce mechanical stress at connection points.
Advantages
The adapter provides a precise 90° change of direction without the need for bending the hard tube, preserving tube integrity and simplifying loop design. Its G1/4 female interface is compatible with common liquid-cooling components, and the 12 mm hard tube connection ensures a snug fit for standard hardline sizes. The silver finish resists visible wear in typical PC environments and supports consistent visual alignment in tight spaces.
Suitable for
 Custom PC liquid cooling loops with 12 mm hard tubing
 Routing tight right-angle turns near radiators, pumps, or reservoirs
 Industrial or laboratory liquid cooling assemblies using G1/4 connections
 Upgrades where tube stress reduction and neat cable-style routing are required
Key specifications
 Angle: 90° right-angle adapter
 Thread type (input): G1/4 female
 Tubing connection (output): 12 mm hard tube fit
 Finish: silver metallic
 Application: hardline liquid cooling and coolant routing
How to use
Install the adapter by threading the G1/4 female side onto a compatible male G1/4 port and secure according to the component manufacturer's torque recommendations. Insert the 12 mm hard tube into the adapter's hardline fitting and ensure an even, flush seating; use the appropriate compression collar or clamping mechanism if the system requires it. Verify alignment before final tightening to avoid cross-threading or undue stress on connected parts. After installation, perform a leak test following standard liquid-cooling procedures.
Usage recommendations
Use compatible 12 mm hard tubing and ensure thread sealing is applied where required by system practice. Avoid overtightening metal threads and check for clearance with nearby components to maintain secure, stress-free tube runs.
