Why Wet Torque?
Due to differences in plating types and thicknesses, materials and
thread quality of components, the coefficient of friction
can vary widely 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 the threads.
Over-tightening causes threads to yield, deform and therefore lose the
ability to maintain an adequate load or clamping force on the
seating area. Extended operation and severe conditions cause
further yielding which promotes possibility of leaks. Improper
installation is the primary cause of leaks in hydraulic
Tompkins firmly recommends the application of the wet-torque method during installation. When you choose not to wet-torque, consistency and quality are compromised for the sake of convenience.
