## Long description

Barrow reservoir T Virus TLYK305 b is a 305 mm cylindrical reservoir designed for custom PC water-cooling loops. Finished in black and white, the reservoir provides coolant storage and clear visual monitoring of flow and fluid level. The compact vertical design is compatible with standard G1/4" fittings and common mounting brackets used in custom builds, helping to stabilize coolant volume, simplify filling and bleeding, and facilitate routine maintenance in bespoke liquid-cooling systems.
Advantages
The reservoir combines a slim cylindrical profile with transparent sections for easy fluid level checks and visual flow observation. Its 305 mm length provides sufficient capacity for most mid-size and full-size custom loops without occupying excessive internal space. The black-and-white finish offers neutral aesthetics that integrate with a wide range of color schemes, and the reservoir accepts standard threaded fittings for flexible installation and routing of tubing.

Рекомендации по использованию
 Для долговечной работы используйте совместимые охлаждающие жидкости, мягкие или жёсткие трубки, и регулярно проверяйте герметичность соединений. Во время первичного запуска проводите заполнение и удаление воздуха в несколько этапов, чтобы избежать работы насоса всухую. Храните резервуар и систему чистыми и промывайте их при смене типа жидкости.
