Please note: Many people over tighten the aluminum fitting on the adapter, which distorts the 37 degree seat and may cause a leak. Both the threads and the seat surface should have a drop or two of oil to smooth the tightening process. Please reference the chart below for maximum torque specifications. Another method of tightening is to bring the nut to "hand tight" and then rotate it another 1/4 turn with the proper wrench.AN Threads | ||||
