SWAGELOK FITTINGS ARE TO BE TIGHTENED TO A TORQUE SPEC, NOT INFINITETIGHTNESS. BE SURE YOUR STARTING POINT IS WRENCH SNUG. A DISTORTEDTUBE MIGHT GIVE A FALSE STARTING POINT.* When making all connections, USE TWO WRENCHES. Don't allow the fittings to turnor twist when tightening.RECONNECTING PRE-SWAGED FITTINGSConnections can be disconnected and retightened many times.When reconnecting, insert the tubing with pre-swaged ferrules into the fitting until thefront ferrule seats in the fitting. Tighten the nut by hand. After tightening to wrenchsnug, rotate the nut about one-quarter turn with a wrench.SWAGELOK PERFORMANCESwagelok fittings have built-in spring interaction between the ferrules. Thiscompensates for temperature changes and allows the fittings to be reconnected manytimes. As the fitting is tightened, a burnishing occurs between the body of the fitting andthe ferrules and between the ferrules and the tube. This action provides the tightestconnection available.6
