6.2. Fittings Torque Values
These specifications are for carbon steel. With Zinc plating always lubricate threads and seals. For stainless
steel, use the high value of the torque range of steel. For brass, use 70% of the torque value of steel. For mixed
metals, use the torque of the lower of the two metals. Torque range is normally calc/- 10%.
