Can be used in all exposed G1/4" threaded openings on the radiator, expansion tank, graphic card cooler or CPU cooler with the AG adapter which is included in delivery. Should an application shortly before the expansion tank be desired... No problem at all. Simply remove the AG adapter and screw a connection into the G1/4" thread on both sides and that's it. Fully potted and therefore absolutely leak-proof. Fully galvanized - no corrosion problems. Full function with any PC temperature gauge compatible with standard PC temperature gauges. Control your PC independently from the BIOS sensors: This is a double protection, similar to the well-known redundancy (double security) of the professional area.
