Reservoir 264mm DDC Acrylic – Barrow PBTT-BBB3230, black

Barrow PBTT-BBB3230 is a 264 mm DDC-compatible acrylic reservoir in black designed for custom PC liquid-cooling loops. The cylindrical transparent body provides coolant capacity and straightforward visual monitoring of fluid level and color. Built to the DDC form factor with a 264 mm length, this reservoir integrates with DDC-style pumps and pump-top assemblies where a compact, standard-size reservoir is required in a watercooling build.

Advantages

The acrylic construction offers clear visibility of coolant flow and simple inspection for air bubbles or contamination. Its 264 mm DDC-compatible dimensions ensure compatibility with a wide range of DDC pumps and mounting solutions. The black finish provides a neutral aesthetic that pairs well with both dark and colored loop components while helping to conceal minor stains or markings. The cylindrical design balances capacity and space efficiency for cases with limited room.

Suitable for

• Custom PC watercooling loops using DDC-style pumps
• Compact or mid-tower builds requiring a 264 mm reservoir
• Setups where visual monitoring of coolant level and color is needed
• Systems that prefer an unobtrusive black reservoir finish

Key specifications

• Material: acrylic (transparent cylindrical body)
• Form factor: DDC-compatible reservoir
• Length: 264 mm (sized for DDC pump assemblies)
• Color/finish: black
• Intended use: custom PC liquid-cooling loops

How to use

Install the reservoir according to the case layout and pump-top assembly instructions, ensuring the 264 mm length and DDC form factor align with the chosen pump. Mount securely using compatible brackets or fittings and connect inlet and outlet tubing with appropriate compression fittings or barbs rated for PC coolant. Fill the loop with the chosen coolant, bleed air from the system following established watercooling procedures, and verify that the pump and fittings are leak-free before normal operation.

Recommendations

Use compatible DDC pump tops and mounting hardware to ensure proper alignment and secure installation. Choose coolant and additives formulated for PC watercooling to avoid material degradation. Regularly inspect the acrylic body for deposits or discoloration and perform scheduled coolant changes to maintain optimal thermal performance and system longevity.
