AC811BT10D AC811 aluminum alloy coupling nut for 5/8 in. OD tube, NS condition.
Part Number: AC811BT10D
Part Type: Nut - Coupling
Condition: NS
Thread: 7/8-18 (AC811 -10)
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 -10 size the AC811 thread is 7/8-18 while the AN818-10 is 7/8-14, so AC811 and AN nuts are not interchangeable in this size.
