Radiator/Reservoir Adapter Barrow PBTS20-V1 b black — Barrow PBTS20-V1 b

Barrow PBTS20-V1 b black is a compact radiator/reservoir adapter designed for liquid cooling systems. It creates a secure mounting interface between a coolant reservoir and radiators or other loop components, helping to keep tubing runs tidy and components reliably positioned in custom PC builds and maintenance operations. The adapter is compatible with Barrow fittings and common cooling hardware, allowing straightforward integration into existing loops.

Advantages

The adapter offers a compact footprint that saves space inside the chassis while providing a solid connection point for the reservoir. Its compatibility with Barrow fittings and standard coolant hardware simplifies installation and reduces the need for additional adapters. The black finish provides a neutral aesthetic that integrates with a wide range of system colors and component styles. Designed for practical installation, it helps maintain consistent flow paths and secure attachment of the reservoir to radiators or mounting brackets.

Suitable for

• Custom PC liquid cooling loops that require a compact reservoir mounting solution
• Integration of cylindrical or bay-type reservoirs with radiators or pump sections
• System builds where organized tubing runs and secure reservoir placement are needed
• Maintenance tasks that involve replacing or repositioning the reservoir

Key specifications

• Material: corrosion-resistant metal and/or treated alloy compatible with coolant use
• Finish: black coating for neutral appearance and surface protection
• Interface: standard threaded ports and mounting points compatible with Barrow fittings
• Form factor: compact adapter bar designed for radiator or bracket attachment
• Compatibility: designed to work with common reservoir shapes used in PC liquid cooling

How to use

Mount the adapter to the radiator, bracket, or chassis location specified in the build plan, aligning the threaded ports with the reservoir inlet/outlet. Use compatible Barrow fittings or recommended threaded connectors to attach tubing or reservoir ports, ensuring all connections are hand-tightened and then secured with the appropriate tool to the manufacturer’s torque guidance. Verify that the adapter and reservoir are firmly supported, check tubing routing to avoid sharp bends, and perform a leak test before powering the system.

Usage recommendations

When installing the adapter, use compatible fittings and quality thread sealant where required. Ensure the reservoir position allows for proper filling and air bleed points. Perform a cold leak test with coolant only and run the pump externally if possible before full system startup. Regularly inspect connections for signs of loosening or corrosion and re-torque fittings after initial run-in.
