While not mandatory,  it is always preferable to fasten a fitting to a cooling device prior to installing the device inside the case. This will eliminate interference issues that may be encountered when working with tools inside of space constrained enclosures. Fasten the fitting by hand until it mates with the surface of the cooling device. The amount of force necessary to screw the fittings down in “finger tight” mating position may vary from one device to another depending on various factors.  Users are advised to always visually check on the actual position of the fitting relative to the device surface rather than solely relying on feel. There should be little -not to exceed the thickness of a sheet of paper, or no visible gap between the fitting lower lip and the device surface. See the illustration below.   For complete long-term safety and leak-free operations, Swiftech® recommends that the fittings be locked in place using the recommended tools and that the torque levels specified below be applied: Recommended Torque Soft Material Minimum Maximum (*) Acetal (POM) and acrylics 1/4 of a turn after initial contact between mating surfaces 1/2 of a turn after initial contact between mating surfaces Hard Materials Recommended Copper, brass, aluminum 1/8 of a turn after initial contact between mating surfaces (*) For full 5mm thread depth – please inspect the device threads prior to applying the maximum recommended torque – when partial threads exist due to application necessity, only apply the minimum torque.         Recommended Tools A small adjustable wrench with jaw opening up to 1” (25.4mm) may be used as a universal tool instead of the specific tools listed below Specific tool sizes Male/male Connectors Fitting base hex:   Flat wrench Lock Nut   Flat or adjustable wrench G1/4 MMEXT Short (11-18mm) Metric: 16mm Inch: 5/8” N/A G1/4 MMEXT Medium (20-33mm) Metric: 16mm Inch: 5/8” Metric: 17mm Inch: adjustable wrench G1/4 MMEXT Long  (41-65mm) Metric: 16mm Inch: 5/8” Metric: 17mm Inch: adjustable wrench
