Conduit Sealing in sub-0C temps

[Candybar]

Looking for a sealing compound that can be used in cold temperatures. Chico is water based and we have had some ruptured sealing fittings due to water expansion when sealing in these cold temps. Heating the conduits is not practical in this instance (limited power, remote location).

CandyBar, Check with your local Crouse-Hinds Rep. There was an explosion somewhere around NJ(I don't know when), and the investigation revealed some leakage through the seals, and that this can happen under the right circumstances. My local rep. says there were some solutions made for your situation, however, he would like to know at what temps. you are working so he can be more precise to the home office engineering team. He says the Chico acts similar to concrete in that it gives off heat as it cures. Once it cures, the insulation in very cold temperatures will shrink allowing gases to flow through. But as noted, they have made some recommended changes. If you can't get in touch with your local Rep., contact me and I will talk to my Rep. again.
Hope this helps.

We are working in Southern Wisconsin and Northern Illinois. We have had high temps in the single digits and teens some days. I will check with my rep here, thanks.

Try Appleton Electric. They make “Kwiko” sealing compound. Long shot—maybe you could substitute something weird like car-radiator antifreeze for water. ;-) ;-) ;-)

Alternately, look up Prudhoe Bay, AK oil refineries on yp.yahoo.com and ask what they use.

I work offshore Louisiana coast and we had some of our sealing fittings that ruptured. After investigating we found out that we had used a certain type of seal and a different manufacturer of sealing compound. We were told that as long as you used the same manufacturer of seal and compound you shouldn't run into this problem.

Thanks for all the help!
