Q: How does this female-to-male adapter change an AN connection?

A: It joins two different AN sizes through a female AN end and a male AN flare end. Select the offered size pair that matches the two adjoining components.

Q: What connects to the 3AN-to-4AN selection?

A: The product identifies this combination as 3AN female to 4AN male. It mates to a male 3AN component and a female 4AN fitting.

Q: Which complete size pairs are offered?

A: The actual size selections are 3AN to 4AN, 4AN to 6AN, 6AN to 8AN, 6AN to 10AN, 8AN to 10AN and 10AN to 12AN.

Q: Which option changes a 6AN female end to a 10AN male end?

A: Choose the complete 6AN to 10AN size selection. A 6AN-to-8AN selection is a different transition.

Q: What is the difference between 6AN to 10AN and 8AN to 10AN?

A: Both have a 10AN male end, but their female ends require different male mating sizes: 6AN and 8AN respectively.

Q: What is the sealing interface?

A: The product specifies a 37-degree AN flare seal. Match the flare seat as well as the selected AN thread size.

Q: What material and surface finish are specified?

A: The product specifies 6061-T6 aluminum alloy with a black anodized finish.

Q: How should I choose one piece or two?

A: Each actual size selection has 1PC and 2PCS options. Choose two for two matching transitions or an identical spare, and compare current totals for the quantity required.

Q: Which assemblies are identified for these size transitions?

A: The product identifies EFI conversions, fuel-return, cooling, transmission and oil-line assemblies with matching AN connections.

Q: What can stop the flare joints from seating correctly?

A: A wrong AN size or gender, debris, damaged flare surfaces or misalignment can prevent seating. Check each interface rather than forcing the connected line into position.
