Alternative to the paper/foil heater hose?

[SpeedracerIndy]

Is there an alternative to the paper/foil heater hose? I know Pelican sells the red stuff but it's $20 per foot, and I need at least 4 feet. That's too much $$ for me. There has to be some type of cheap alternative out there. I'm so sick of busting up my knuckles trying to get this stuff on, then having it crush and be toast.

Try aircraftspruce.com. Don't have a catalog at work but they have the neoprene hose for heater and ducts that goes on very easy. Price about $5. ft.

You can get dryer hose in 4"at any hardware store. I'll cost you $5.00 for about 10 feet. It'l look like arse but it does work. The defrost ducts in my land cruiser are dryer hose.

Any aircraft-parts supply house--Aircraft Spruce, Wicks, etc.--sells the three grades of hose ("the red stuff") that are used for similar purposes on airplanes. CAT, SCAT and SCEET, they're called, and the differences have to do with temperature and pressure ratings. It's been awhile, but I can't remember any of them going for $20 a foot, and I sure used yards of them in my various airplanes.

Yeah, you can use dryer hose. You can also use garden hose for oil lines.

Heh he.

Me thinks dryer hose is a tad large.

Thanks for the input guys! I found some of the "red stuff" on those websites. It looks like the SCAT is rated up to 450 F and the SCEET is rated up to 500 F. Just one more thing, what is the ID of our heater hoses?

My year (1982) uses two sizes: 50 mm and 60 mm. 2" matches 50 mm very well. 2.5" is a little bigger than 60mm, but it clamps in place fine. I used the black CEET in the engine compartment and the red SCEET underneath. These are 2-ply while CAT and SCAT are 1-ply. I ordered:

3 ft. CEET-8 (2")
2 ft. CEET-10 (2.5")
4 ft. SCEET-10 (2.5")

and was able to do everthing with some left over. The total cost was about $70.

the dryer hose bit was funny but I'd be careful - even in a joke - telling somebody to use something that will likely cause an engine fire (just like the way those vinyl hoses cause dryer fires...)

as a widely known author on Porsches, somebody could reasonably rely on your expretise yada yada...

(true even if your book didn't have much Pcar restoration content, encouraged lawlessness, and siphoned money ffrom a corporation.....)

See - not always fun being an author is it? World is full of critics.

Best...

Volkswagen camper vans use the identical heater hoses (60mm) for about $5 each. Just replaced all of mine for about $20.

[SpeedracerIndy]

Does anyone have a picture of an engine with the SCAT or SCEET hose? I am thinking about just ordering it all in the red stuff for simplicity, but want to know how that will look. Thanks!

And I'll pass on the drier hose idea, I think most people would know NOT to hook up a vinyl hose to the heat exchangers, or at least I hope so.

Here's a photo showing an engine with CEET (black) for comparison.

Thanks Scott and others for the input! I went ahead and ordered five feet of the SCEET to do all of the hoses, with the exception of those going to the flapper boxes since they are fine. I have back dated heating so I don't need the big long one going across the top of the engine, and it's all in the 2.5" size. If it looks too cheesy I might end up replacing the visible ones in the engine bay with the black CEET.

Oh, I don't know..........the dryer gets pretty damn hot.

Now, let's take a reality check. Did the thread not start off asking about a PAPER and foil hose?

No, I'm not suggesting you use dryer hose, but temperature wise, I don't think it would fail. Ol' UncleBilly didn't mean no harm.

SCAT hose or Silicone Air Tubing hose, can be bought in odd lengths at your aircraft repair shop. When I use it, sometimes I need to fold the end of the hose back into itself to fit a little smaller diameter.

I can't remember if I used Scat 10 or SCAT 12 for the heater hoses. I know that if it will bolt to the exhaust manifold of a Piper Aircraft, it will probably take the heat of a Porsche heat exchanger.

Good luck,

The dryer hose would take the heat - no doubt but I agree it is a little on the bulky side. I'm using it on 3" ducts in the land cruiser. The webbing between the rings is slightly elastic so it fits tightly on the 3" male connections.

There are different sizes of dryer hose, not just the big stuff most people have.

I bought SCAT hose from AirCraft Spruce. I think I paid around $50 for 8-10 feet. It is good stuff and has held up well on my backdated 89.

[randyrap]

I'm pretty sure it is SCAT #10. Might be a few extra bucks but it is the best stuff you can get. Very strong and still flexible. Here is a pic of my backdated 3.0 litre.



Thanks ....................... Randy

I’m sure you are right that the dryer hose would work just fine, but I think I'll stick to the SCEET for aesthetic reasons.

edit: I misunderstood Zeke's intentions in his post.

Thank you for posting the picture Randy. That is what I ordered also. My car also has backdated heat and no A/C so your engine bay should be similar to what mine will look like.
