Hoses for distillery

[cede]

Hi,
I was on this page http://mykin.com/rubber-chemical-resistance-chart-3 to look at some materials compatibility and I was comparing EDPM and Butyl.
I know most of plastics here are rejected until proven safe for the hobby, but I wanted to do some internet research on my own.
I was looking for some GC/MS tests on those polymers EDPM,Butyl, Pt cured Silicone checking if they could leak something into the vapor/liquid.

So while searching on butyl, I found Glidetech hoses specially developed for distilleries but they do not mention the material.

I made a forum search on glidetech on the forum and gg HD search an nothing came up.
Other hoses that can withstand ethanol are butyl, but this one is said to be usable with 96% ethanol and congeners.

Guessing it’s PTFE aka Teflon

Should be safe for use at high proof and hot

Glidetech hoses do have an inner white layer and are quite stiff, so it's very possible they are lined with ptfe.

Do to the forums stricked safety rules we want members to error on the side of safety. Guessing can be dangerous so our stance and advice would be to avoid use unless there is proven documentation.

Agreed that guessing isn’t a good strategy but these do look like a handy product designed specifically for high abv alcohol.

Perhaps made for alcohol liquid transfer but indication they are safe for hot vapor though.
And not cheap at over $20/ft.

Bushman, I don't get your point.
Isn't it being of the safe side to use products developed for our needs ?

Wasn't responding to your post but to responses to your post about guessing about a product.

I bought a 1/2" diameter hose made of PTFE for transferring spirits.
That along with a 1/4" ID copper pipe and something to seal the opening makes it fairly easy.
Insert both into the container, blow air into the container using the copper pipe, spirits flow out the PTFE pipe into the next container.

I use the same sort of method when I want to drain brake fluid from the master cylinder in my cars, as it's recommended to flush old brake fluid regularly.
When doing that I use cheap vinyl hoses that I just throw away after but it's the same method.
Never a good idea to try and siphon anything caustic by sucking on the pipe that the caustic fluid will travel through.
Instead create positive pressure by blowing into one pipe which will push the fluid out through the other.

All that is just extra info, main comment is yes PTFE pipes are expensive.
So is cancer treatment or whatever else you may need if you don't use safe materials.

Ah, ok, wasn't that clear in my head under flu attack !

nerdybrewer We use the same technique !
For the brakes, I bought a EZ bleed systems that you plug on a tire to get air pressure, works great for bleeding and changing brake fluids.

I have an easy bleed too.

The PTFE hose isn't too hard to find for less than what was mentioned previously in this thread.

A factory in the Netherlands, Chemours, making teflon by the GenX-process spills its waste in the water, so the population living in the far neighbourhood of that factory ingests this waste via the drinking water. The GenX-process replaces the process that used perfluoroctaneacid.
Which could mean: a distiller in that region might prevent being polluted by using PTFE-tape, but than is polluted by the same PTFE-tape via the tap water he uses to make his mash or diluting his product.
This factory was owned by a USoA-company: Dupont.

So when I use this safe white tape, people in Ohio or West-Virginia are poisoned?

Thought I might post this in this topic .
I use Silicone Rubber hose for transferring wash . I have been keeping it in an old fermenter full of Sodium Meta-Bi-sulfide ( Sterilizing solution ) which I thought was a good way to store it .

I'd noticed that it had gone slightly whitish over a 12-18 month period compared to the translucent look it had when new .
Anyway was using it to transfer hot Rum wash during production , bent the hose on itself to stop flow for a second when it ripped open spewing hot sticky shit everywhere .

On closer inspection it appears that the inner of the tube is a different material to the outer .

As I pulled it apart , the method of construction became apparent ...it appears like some sort of spiral construction that is decomposed by the oxidizing forces of the Sodium Meta-Bisulfide

Not saying its bad , just don't store it like I did

Silicone hoses have to be stored dry with no weight on them.
They're nice for brewing, but if they change color, they're dead. That's what I learned too.
