Re: [vintagvw] Gasket material
Bert et all, Sorry but Im a bit grey in this area due to the fact that this part of the world is quite warm and VW heaters are almost always disabled in my city at least. In fact I have yet to see a bug with working heaters. Thanks to irresponsible mechs who throw out heater parts everytime the engine is taken off or the car goes for any work. I did not know there were bakelite parts down there. Is it the short tube which clears thru the body under the rear seat?? Will try to knock on the ones in my 68 next time I pop the rear seat butt rest up. I thought they were metal. I have seen rubber gaskits at the boneyard. I thought they went where the big accordion pipes joined with the body with the mentioned bakelite (?) pipes. Could this be what you are referring to?? They are bright orangish red. I think I have seen these advertised on websites. Could this be the crumbled material you found?? Ironically Ive always noted these to be in very good shape, even with 40 odd years of abuse in our tropical weather and no love. Best wishes and regards, Asad Karachi, Pakistan.

Re: [vintagvw] Gasket material
Adding something here, Some quick searching led me to the VW heritage website. http://www.vwheritage.com/vwh/VW-Beetle-Parts/Exhaust-Heating/Heating-System/?templateID=vwh See item number 12. This is the red rubber seal I was talking about. Four needed per car. It goes at each end of the big accordion hose. Ah yes the body pipe is bakelite! Item 9. I cant figure out item number 10. its not listed. Asad.

Re: [vintagvw] Gasket material
Bert, I think the RTV would probably do a fine job. No oil or other pertoleum products would be in contact with that area, so the RTV is an excellent candidate. I have always found my VW's to adequate or better in the cold...on trips! In town in rush hour traffic at 30F or below is iffy. I have had some of the marine blowers for several years that I am going to mount inside my wife's Ghia engine compartment and push the air with themshe only has a 6 mile comute and has decided that her Ghia is her daily driver. Please let us know how the felt material works out! Cheers, dave -- --- Enough sunlight reaches the Earth *every* hour to meet the world's energy demand for an entire year.so, what do we do with it?

Spring and autumn are beautiful, but too short for a VW enthusiast's hobby. The VW heating system can be marginally adequate in winter if it's in good repair, well sealed, and the engine is running at proper temperature. Unfortunately, it's dependent on engine speed, which is unreliable in urban commuting traffic. My local experienced VW shadetree mechanic assures me that a ring of RTV silicone sealant around the bakelite pipe flange will create a good, heat-resistant seal on the flange where the heat tube enters the body. I'm not convinced, so I will probably attempt to cut a pair of seals from something else. Your red rubber gaskets might be some kind of high-temperature silicone rubber. I'll ask around. The good news is that I found a couple of VW carcasses with the short underseat warm-air tube insulation intact, and used them as models for my recreations. I cut new covers from scraps of vinyl-coated canvas from a local sign shop: it's the stuff they use for banner signs and it has a texture and apparent strength identical to the factory material. An upholstery shop gave me some pieces of jute insulation (about 15mm or 5/8 thick and colored grey) that matches the original almost perfectly. I found two of the flaps that fit inside the pipes to open the rear footwell outlets, and they cleaned up very nicely. I bent new control wires from a scrap heater cable. I'll report back when it's all together.
