Primer O Rings
Anyone have a model number for replacement O rings for the primer? Aircraft is 1951 170A. Thanks
Re: Primer O Rings
I should have wrote “part number.”
Re: Primer O Rings
This is the primer kit I got from Aircraft Spruce that worked great. All it has is two o-rings (if I was at the hangar I could give you the individual o-ring part numbers) and some fuel lube. Unfortunately they show they are out of stock right now.

An originality nut (mostly) for the right reasons.

Re: Primer O Rings
The part numbers of the O-rings themselves are MS29513-012 (70 Duro Nitrile /“fuel resistant” NBR); or NAS1593-012/M83248/1-012 (fluorocarbon synthetic rubber -”Viton”). MCM83248/1-012 is McFarlane’s part number for it's FAA-PMA Viton replacements, but as George pointed out, McFarlane also sells them in pairs in a replacement "kit."

Re: Primer O Rings
This worked really well and was easy. Open primer and spray in notch to lubricate O rings.
