AC811BT12 AC811 brass coupling nut for 3/4 in. OD tube, NS condition.
Part Number: AC811BT12
Part Type: Nut - Coupling
Condition: NS
Thread: 1-1/16-16 (AC811 -12)
The AC811-BT is the coupling nut for the three-piece AC811 flared tube system (fitting, AC811-T sleeve and BT nut), the pre-AN Army Air Corps standard that AN fittings replaced during WWII. In the -12 size the AC811 thread is 1-1/16-16 while the AN818-12 is 1-1/16-12, so AC811 and AN nuts are not interchangeable in this size.
