AN FITTINGS AN818-4D NUT
I used this as part of a primer line installation on a 0-320 Lycoming. It worked well, the challenge was attaching the cone to the copper tubing, a machine shop had to braze it. The nozzle ports needed a 1/8 npt tap run down the cylinder to allow enough thread engagement for the nozzle. The copper tubing is challenging to flare since it is so small, re-doing a flare was needed to make a leak free connection.
I live in Michigan. My order was shipped from Georgia. It would be nice to order parts from Chicago.
Every invoice has a general Certificate of Conformance, but if a manufacturer cert is required, you must request at the time of order and there is a charge for the paperwork.
The weight of AN818-6D is approximately .056 lbs.
No, these do not have any pre-drilled holes for safety wiring.
This is the nut only. The sleeve part number is AN819, add dash number for size and material.
