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
(KMT Waterjet P/N 10084440) is highly recommended for tightening of
stainless steel HP water fittings.
A torque wrench kit is available from KMT Waterjet. (KMT Waterjet
P/N 49895436).
