UNION CONE AN800-2
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.
