I am ready to install the Hatori SB-19 muffler back on my YS91 SR for my Trex 700, and I can't find a gasket anywhere. After searching, and looking online to see what comes with the Hatori SB-19 muffler, I'm starting to think it didn't come with a gasket, and that perhaps I wasn't using one.

I do have muffler gaskets for my Align 91H motor and Hatori SB20 Muffler. I'm thinkng that the gaskets that I have for the Align 91H/Hatori actually came with the Align engine and not with the muffler.

Anyway, who makes a gasket for the YS91 SR, and who sells it. Apparently it is quite hard to find. Haven't seen one at the normal on-line hobby shops.

Thanks guys.

I just use epoxy, 30 minute works well. You don't use a lot of it. When it comes time to take the header off I just tap it with a rubber mallet. Been doing it for years.

SB-18s and SB20s all had 4 or so gaskets packaged with the mufflers. So, I'm inclined to think the same for SB-19. These tend to stick to the engine/muffler and will rip when you remove the header for maintenance.

I would suggest you contact Rich at HatoriUSA at http://www.hatoriusa.com/ for replacement and future spares.

Both of my SB-19s didn't come with any gaskets. I use high temp ATV but it only lasts 150 flights or so.

Please stand by for faster service!

no gasket was included with the sb19, and it's not needed. bolt it on, tighten it down and go fly. IF it makes you feel better, use a smear of red rtv.

No gasket included nor needed. If there is a burning desire to put something in there, use a very sparing amount. The face of both mating surfaces is very smooth and don't need a lot of crap in between. If you do go overboard, you just risk it loosening up later when the material burns away or compresses.

SB-19s don't come with gaskets. I smear a little bathroom chalk. No even high-temp and no problems. Been doing this for years.
