1.
Seal faces must be in contact and the fitting fully
hand tightened before marking flats.
2.
Flats method is most accurate for the first
assembly cycle, for multiple disassembly/
assembly cycles torque values are more reliable.
3.
Tightening 2 flats or more is analogous to sever
over torque and may damage seal faces.

1. The torque values obtained from tightening pipe
threads can vary considerably depending on
thread condition. Adequate sealing can occur at
values much lower than the maximum values listed
above. Only enough torque to achieve adequate
sealing should be used.
2. When using a male tapered pipe thread with a
female straight or parallel pipe thread, maximum
values are 50% of those listed in the table.
3. If thread sealant is used, maximum values shown
should be decreased by 25%.
