FLANGE TYPE HOSE
FITTINGS
Check flange fittings for smooth, tight fit of match-
ing surfaces. If any capscrews are loose or if match-
ing surfaces are not tight, tighten the loose screw
then tighten the diagonally opposite cap screw.
Tighten the two remaining capscrews, then torque
all four screws as specified in the Torque Chart in
this manual.
Tolerance is ± 10%. The torques given are enough
for the given size connection with the recommend-
ed working pressure. Torques can be increased to
the maximum shown for each screw size if desired.
DO NOT use these values if a different torque value
or tightening procedure is listed for a specific appli-
cation. Torque values listed are for general use only.
Check tightness of cap screws periodically.
Proceesor bolts are designed to fail under predeter-
mined loads. Always replace bolts with the identical
grade.
Make sure fastener threads are clean and properly
engaged. This will prevent them from failing when
tightening.

Do not use air wrenches. Tighten each bolt equal-
ly in an alternating pattern. Do not overtighten.
Use only metric tools on metric hardware. Other
tools may not fit properly. They may slip and cause
injury.
