Top cap supports rubber washers for a proper seal, including two predrilled G1/4" ports for fittings. Heat-resistant Acrylic Tank: The Pacific PT Series tube reservoirs feature reliable, light weighted POM and PMMA construction, which is crystal clear and highly durable. High quality acrylic (PMMA) tube maximum working temperature: 131 (55). Remarkable Expansion: A bracket at each endholds the Pacific PT60-S firmly inside the chassis and allows enthusiasts to not only build up an aesthetically superior liquid cooling system but also incorporate externally-modular upgrades for their chassis. The series provides multiple sizes for users to build the ultimate in custom configurations, and for a truly extraordinary chassis, the reservoir can be installed horizontally. It is strongly recommended to use market proven pre-mix coolant, such as Thermaltake Coolant 1000. It offers great performance while preventing the entire cooling system - copper, brass, nickel, aluminum, and steel - from corrosion. 2 Years Warranty
