*Tolerance ± 10%. The torques given are enough
for the given size connection with the
recommended working pressure. Torques can be
increased to the maximum shown for each cap
screw size if desired.
Increasing cap screw torque beyond this maximum
will result in flange and cap screw bending and
connection failures.
