NOTE
Measurements are made with lubricated components and a calibrated torque wrench.
Inconsistencies in wrench settings, lubrication, and technique, may not produce a
leak tight seal. If leakage persists, increase the torque until the components seal, do
not exceed a value 15% greater than shown. If leakage persists there is a component
problem. EXCESSIVE TORQUE MAY DAMAGE OR REDUCE THE LIFE OF
COMPONENTS.
Use of an antiseize thread lubricant, like High Purity Goop
(P/N 10084440) is highly recommended for tightening of stainless steel HP water
fittings.
A torque wrench kit is available from KMT Waterjet. (P/N 49895436).
