AC811HT8D AC811 aluminum alloy flared tube union for 1/2 in. OD tube, NS condition.
Part Number: AC811HT8D
Part Type: Union - Flared Tube
Condition: NS
Thread: 3/4-18 (AC811 -8), all tube ports
The AC811HT8D is an aluminum alloy flared tube union from the pre-AN Army Air Corps AC811 flared tube fitting system, used with AC811-BT nuts and AC811-T sleeves. The AN counterpart is the AN815, but in the -8 size the AC811 tube thread is 3/4-18 versus 3/4-16 on AN, so replace it as a complete unit with matching AC811 nuts and sleeves.
