This bundle includes the ES TPV hose from Alphacool's Enterprise Solutions and Tec Protect 2 Clear coolant. The ES TPV hose from Alphacool's Enterprise Solutions series is characterized by its high resistance to acids, bases and external influences and has an exceptional durability compared to conventional PVC hoses. Optimized for server and workstation systems. What is the advantage of EPDM? Compared to commercially available PVC hoses, Alphacool's EPDM tube is significantly more temperature-resistant and enables working temperatures well in excess of 100 ?C. Even at higher water temperatures, the EPDM tube remains dimensionally stable and prevents the tube from warping in places with tighter bending radii or connections. This eliminates the risk of the water circuit leaking or the water flow being obstructed. Technical Data Length: 3.3m Material Hose: Ethylene propylene diene rubber (EPDM, without talc) Hose Size: outside 8 mm / inside 5 mm Every water cooling system requires coolant for heat transfer. With the Alphacool Tec Protect 2 Clear coolant you get a ready-made mixture that already contains all the necessary additives and can be used directly from the bottle. The additives contained ensure a lower surface tension of the water, which significantly reduces the formation of foam and air bubbles. Alphacool Tec Protect 2 protects the circuit from bacteria and algae formation and is an ideal lubricant for all water cooling pumps. Alphacool Tec Protect 2 Clear is suitable for all materials that are usually integrated into the water cycle of a water cooling system. These include materials such as copper, brass, nickel, chrome plating, aluminium, acrylic glass (PMMA), POM, PPS-GF40, PETG, acrylic, PVC and EPDM/PP.
