BobN,

A couple of weeks ago you posted a picture of a Bonanza's firewall under construction.  It shows a firewall pass-thru fitting with a 90 deg bend and some sort of flange attached to firewall.  What is that fitting made of?

         A couple of weeks ago you           posted a picture of a Bonanza's firewall under construction.            It shows a firewall pass-thru fitting with a 90 deg bend and           some sort of flange attached to firewall.  What is that           fitting made of?

     I'm not Bob, but stainless grab bars work well. Just find versions     that have the flange welded onto the bend. I needed a straight shot     off the firewall for mine, so I cut it short enough that I just had     a short stub left for clamping the fire sleeve. Ebay has had smaller     (~1") stainless flanged stubs in the past, but I can't find the link     now.

   Beech fabricated their fittings from stainless

   steel.

When I installed mine I put the pipe end of the fitting inside the cockpit This is purely cosmetic, the firesleeve and sealer clamp are then out of sight 

From the engine side you only see the wires bundle going into the fitting
