Replacement Reservoir Barrow PBTT-WBW3230 — Acrylic 264 mm, white

Barrow PBTT-WBW3230 is an acrylic replacement reservoir 264 mm in length finished in white, designed for custom liquid cooling loops in desktop PCs. The rigid acrylic body provides clear visibility of coolant level and flow, and the reservoir serves as an expansion and storage chamber within a watercooling circuit. It is intended for use where a compact, visually neutral reservoir is required and is compatible with standard fittings used in custom cooling setups.

Advantages

The reservoir’s acrylic construction offers high transparency for easy visual monitoring of coolant color and level while maintaining structural rigidity. Its 264 mm length provides sufficient volume for coolant circulation and air separation without occupying excessive internal space in a PC case. The white finish gives a neutral aesthetic that blends with light-themed builds or contrasts with colored coolant for clearer visibility. The component is created for straightforward installation into existing custom loops using common fittings and mounting options.

Suitable for

• Custom PC watercooling loops requiring an inline expansion reservoir
• System upgrades or maintenance where coolant visibility and additional volume are needed
• Builds that require a compact, rigid acrylic reservoir with a neutral white appearance

Key specifications

• Material: rigid acrylic for clear coolant visibility
• Length: 264 mm
• Finish: white
• Function: coolant expansion and storage in liquid cooling circuits
• Compatibility: designed for custom PC loop installations using standard fittings

How to use

Install the reservoir inline within the return or feed section of a custom loop following the manufacturer’s guidance for orientation and mounting. Connect tubing or hose fittings compatible with the reservoir ports and ensure all connections are tightened to prevent leaks. Fill the loop with appropriate coolant, perform leak testing at low pump speed, and bleed air from the system until steady flow and stable coolant level are achieved. Periodically inspect the reservoir for contaminants, sediment, or changes in coolant color that indicate maintenance is required.

Recommendations

Use corrosion-inhibited, manufacturer-recommended coolant compatible with acrylic, avoid solvents or cleaners that can haze or crack acrylic, and perform regular visual inspections. When installing in tight layouts, confirm available clearance for the 264 mm length and select fittings that provide secure, leak-free connections.
