Torque Values: Why Wet Torque?

Wet torque is the practice of using hydraulic fluid to lubricate the threads and o-rings of the fittings before installation. Due to differences in materials, plating types, thickness, and thread quality of different components, the coefficient of friction varies greatly on any given assembly. Lubrication not only produces a more consistent coefficient of friction, it increases clamping force on sealing area with less torque on threads. Over tightening causes threads to yield, deform, and therefore lose their ability to maintain an adequate load or clamping force on the seating area. Extended operation and severe conditions cause further yielding which results in leaks. Failure to wet torque is to compromise consistency and quality for convenience. Use the lowest torque value from the chart when wet torquing.
