Stainless braided hose question
 

I want to put stainless braided hose from my thermostat housing to my headers, it is 1" hose.
What dash # would be equivelant to 1" hose?

I believe that would be AN-12... very expensive stuff!!

I think it's usually closest to multiples of 1/16". 1" ID is about -16. Double check your measurement, 1" sounds big for a thermostat outlet. Remember it's the inside diameter of the hose your measuring. The S/S line is kind of an overkill for that application. You could just use the braided hose covers and clamp covers that Merc uses on their motors.
I've also used "Push Loc" hose with brass JIC fittings. It's not as flashy as the S/S stuff, but it's a lot cheaper and makes for a very clean looking installation.

-16

Thank you,
I will double check but I believe the hose said 1"

So we all agree it -16 right?

Thanks
Mark

From Aeroquip catalog

#4 = ..25 hose id inches
#5 = .31"
#6 = .38"
#8 = .50"
#10 = .63"
#12 = .75"
#16 = 1.00"
#20 = 1.25"

Now I confused I have a book at home and it says -18 is 1"

But I did double check and it is 1" to the CMI's from the stainless thermostat housing.

Any one else care to guess.

Thanks again:confused:

I used -12 from the thermostat housing to Gill manifolds. I do not think you have to go any larger. Take a look at the size of the fittings you will be threading your adapters into. The hose will not flow anymore than can fit past the restriction in the adapter.

Gary,

Where did you buy the braided hose covers you referred to? Is it called that exactly? I'm having trouble finding it.

Thanks in advance.

Kelley,
You can get braided hose covers through mail order places like Summit or Jegs. Local auto parts stores that deal with high perf parts or have a big selection of dress up items should also have them.

Mr Cig,
I would think -12 or 3/4" ID would be more than enough to flow to the manifold. Check out the thermostat outlet and the water inlet on the manifold. They are almost certainly pipe thread, probably 1/2" NPT or maybe 3/4" NPT. Buy the adapters, NPT to JIC fittings, either -12 or -16 and the hose and appropriate fittings. The majority of restriction will come from the thermostat outlet even with a -12 hose.
BTW, don't mix up SAE and JIC hydraulic fittings.

Kelly,
Like he said, Summit or JEGS has them as kits with the S/S hose sleeve and anodized clamp covers. The best price I've seen was in J C Whitney. They sell aluminum braid hose covers that look just as good for less than 1/2 the price and are easier to work with.

Gary, thanks for the tip. I had priced the real hoses and stuff a long time ago and dropped that idea when I figured out what it would run me!!

I didn't even know there were sleeves available, and didn't know where to start looking. I'll check out JC Whitney and the others. Thanks again for the info.

Mark,

Let me know what you find out, and how they sell it. When I put the headers on it made my hose to short and I had to extend it. I have wanted to switch to braided since. I'm sure it come by the foot. Winners circle had it in Joliet, I ordered it and after 3 weeks of not comming in I cancelled it and never got it.

I E-mailed Earls and he said that -18 part#300018 is equivalent to 1"I.D. hose.
I am going to call Summit Racing for a price.
