Reservoir Barrow TLYK255 255mm black white — PC water-cooling reservoir 255 mm

Barrow TLYK255 is a 255 mm cylindrical reservoir designed for PC water-cooling systems in a black and white finish. The reservoir holds coolant for custom loop configurations and provides visible fluid capacity to monitor levels. It features standard inlet and outlet ports for tubing and fittings and is intended for mounting in compatible cases or bracket systems to form part of a complete water-cooling circuit.

Advantages

The reservoir offers a compact, tall-profile design that combines visual clarity of coolant level with a stable mounting footprint. Its cylindrical construction supports easy integration with common tubing and fittings, while the black-and-white finish provides a neutral aesthetic that fits many builds. The visible coolant column simplifies filling and bleeding procedures and reduces the need to disassemble other loop components during routine checks.

Suitable for

• Custom PC liquid-cooling loops for CPUs and GPUs
• Systems requiring a visible coolant level indicator
• Builds where a 255 mm cylindrical reservoir fits available mounting space
• Maintenance tasks such as filling, draining, and bleeding coolant

Key specifications

• Form factor: cylindrical reservoir, 255 mm length
• Finish: black and white options
• Ports: inlet and outlet connections for tubing and fittings (standard thread compatibility)
• Mounting: designed for case or bracket installation compatible with reservoirs of similar size
• Material: transparent body for visual coolant monitoring with opaque end caps (black/white)

How to use

Install the reservoir in a compatible mounting location using the appropriate brackets or case mounting points. Connect inlet and outlet tubing using compatible fittings and ensure all threaded connections are tightened to prevent leaks. Fill the reservoir with the chosen coolant until the visible level reaches the recommended fill mark, then run the pump to circulate and bleed trapped air from the loop. Check for leaks and confirm flow before normal operation.

Recommendations

Use coolant formulated for PC water-cooling and follow manufacturer guidance on mixture ratios and anti-corrosion additives. When installing, support the reservoir securely to avoid strain on tubing and fittings, and perform periodic visual inspections of coolant level and clarity to detect contamination or evaporation. During maintenance, isolate power to the pump and drain coolant into a suitable container following local disposal rules.
