copper crush gasket torque
(OP)
Is 500-510 lb.-ft torque on a 1-3/4 -16 brass plug using a copper crush gasket excessive?
This torque is listed in an aircraft engine Table of Limits and seems very high. Another engine manufacturer shows 130 degrees rotation for a comparative item.
I thought that one didn't want to totally "crush" a copper crush gasket, and the best method is degrees of rotation.
