Need help selecting components for oven

General Composites Discussions Equipment Talk
#1

I’m at a bit of a hicup in my oven build.

I’m in need of some vacuum hoses that I could attach to a manifold for inside of the oven. I looked on siliconhose.com but shipping is $35 with UPS for a few feet of silicone… not acceptable.
Any suggestions for where I might find some alternate products that could work?

I also thought that some quick disconnects (the style that are used on compressed air hoses) would be useful although I can’t seem to find them.

Are there vacuum hoses similar to compressed air hoses that can handle max400F?

Thanks!

We buy all of our stuff from airtech.

They have the hoses and the quick disconnects as well as the vacuum probes. I believe their hoses are good to high temp like 500 or something.

Air tech doesn’t seem to have much selection for hoses. https://store.airtechintl.com/htm/defaultnetscape.htm

I think you will find the airtech hose are quite expensive since these have an internal spring through their length to prevent collapse in autoclave which run under high pressure and they also include a pressed on threaded end fitting but not the actual couplings.

For a regular oven you just need a silicone hose with nice thick wall. I usually get these from a hydraulic hose suppliers.

Second what fasta says. You should be able to get hose from a local hydraulics shop able to handle any temperature you would use for composites. I believe we used good year hoses with good success
