I just got my HF Pot and assembled all the fittings per Steve Swiger (which looks great!) and did my first pressure test. After hooking up to compressor, let fill, and then close valve to compressor I could hear a hissing. I noticed that the 3/8" fitting that goes inside/outside the Pot had a leak - a major one I might add. I removed the factory fitting and noticed there was a rubber gasket on the inside that was broken.

Any suggestions?? Is my only option to call HF and wait for a lid or gasket replacement?

thanks!

For fear of repeating myself, and being shouted down by the mob, you can use Permatex, or GE brand auto gasket sealant and make your own gasket. Make sure it is the gasket compound made for pressure. You should be good to go in less than an hour.

Hey! You there! Innovative thinking will NOT be tolerated! That's it, you're out of the mob!

hehe...sounds like a good solution to me. Would it help to cut a new gasket out of gasket material and then the permatex to seal it? Also, what's the effect of vacuum on that stuff, you know, going back and forth, think it'd work it loose?
 
It's been some time since I built my pot, but I think that I just used a big rubber washer that I got from Home Depot for next to nothing.
 
Karl, on pressure mode we take the pots up to 40-60 pounds. Best vacuum is only about 14 pounds in the other direction. If it holds for the pressure, it will hold for the vacuum no problem!

Both the solutions listed should work fine.

I think that you might have misunderstood Karl's question. I also wonder if the push from pressure and the pull of vacuum wouldn't cause permetexy sealant to degrade quicker.

Good one Karl. Like the kid at work would say, "stop making sense!!"

Wow, thats two in one day, you guys are making me blush. [:I]

Good luck on the gasket issue. It's a shame to hear about this problem. We where doing quite well with the pots there for a while.
 
We have had some good luck with using gorilla glue. It expands to fill all the gaps and it will handle pressure and vaccuum. Just let it set for 24 hours or you will have a hole again.
 
Thanks for all the responses! I went to HD and bought a rubber washer(the ones that you put between a garden hose and spicket! It is almost a perfect fit, although the diameter required some trimming. It still leaks there a little, so I am goint to try the permatex next.

The gorilla glue sounds easy, but seems like a potential mess if it doesn't!

BTW, I called HF and they are sending me a new lid - although it said it would take 6-8 weeks to ship a new one since they didn't have lids in stock! (I will give them good credit for customer service though!)
 
I have tried the rubber washer from HD and also permatex and can't seem to get a seal. Does anyone have any advice on the gorilla glue idea? I am worried if it doesn't work - I am stuck with glued fittings! :)

thanks,
Austin
 
Do you have a vacuum setup? If so, seal it up and apply vacuum. once you are sucking pretty good apply thin CA where it leaks. That will seal the deep, thin cracks. Then apply a bead of medium or thick CA. That will seal any thicker cracks that the thin couldn't seal or it will just create a nice bead. If the bead forms you know your thin sealed it.

Hi GK,
Thanks for your post. Are you saying that with vacuum I should apply the CA after sealing with gorilla glue or apply the GA without any rubber gasket or glue altogether?

thanks,
Austin

I think he means, before you do anything else, pull a vacuum and apply the CA. The vacuum will pull the CA in and seal the voids. If memory serves, he did that on his set up. He had some fittings that where porous enough to allow a small amount of air to pass through them under extreme enough conditions. The vac will force the CA into the small voids and hopefully seal your leaks.
