Torque Specifications

Many people over tighten the aluminum fitting on the adapter, which distorts the 37 degree seat, and may cause leakage. Both the threads and the seat surface should have a drop or two of oil to smooth the tightening process. The maximum torque specifications are listed here. (An alternate method of tightening is to bring the nut to “hand-tight” and then rotate it another turn with the proper wrench.)

Fitting Size	Max. Torque in Foot Pounds
3	8.75
4	11.5
6	16.25
8	29
10	35
12	45
16	70
20	85
