The Alphacool Eisbaer TPV Extension Set 90° is the easiest way to connect Alphacool's expandable AIO systems with additional components. The Extension Set is compatible with all Alphacool AIO systems for processors and graphics cards. The 12.7/7.6 mm TPV hoses are each 30 cm long and have a 90° Alphacool TPV metal connector with a G¼" thread at one end. At the other end there is a quick-release coupling with a male or female connection. The safety quick-release fasteners have a twist lock. This basically prevents the quick-release fastener from opening accidentally. If you want to use the Extension Set to expand an Alphacool AIO solution with another product, you must pay attention to where you use the male and female connectors. The hose with the quick-release male connector should always be mounted on the water outlet. The hose with the female quick-release connector, on the other hand, is used at the water inlet. Instructions for use: Please use only in conjunction with clear, transparent water cooling fluids. The particles and additives in Pastel fluids can clog and permanently damage water cooling products such as radiators, pumps, coolers, and hoses. This may also void the manufacturer's warranty.
