RTV & Cable glands

Hi guys,
Anyone could point me to the right direction to get some good RTV to fill a couple of Swagelok cable glands?

Philippe,

I have been using 3M 5200 marine sealant in all my homebuild projects. Works great have had no leaks.

Phillipe,
the sealant you want is RTV-615..

this is a great insulator but more importantly it will cure in an air tight enviroment which typical silicon based sealants will not.. if the item you want to cure is exposed at some point to the atmosphere the prior suggestion would work..

be fore warned RTV 615 isnot cheap.. it runs about $100 per pint..

Joe,

Hope you'll pardon the silly question but, if RTV-615 will cure in an anaerobic environment, what keeps it from curing in the pot?

Rob

P.S.--Sorry, but it's late enough at night that silly questions just naturally occur!

RTV-615 is a 2 part product, although the main agent has to remain sealed when not in use, it will not cure until the "hardner"/catalyst is added, in the same manner fiberglass is cured..

This product is also optically clear (well pretty clear) so inspection of whatever is encased in the sealer is possible..

here is some info

For those of you who, like me, were wondering what the acronym RTV meant, it is Room Temperature Vulcanising. Thought I'd share that as it took me a while to find out.

cheers

Joe,

Thanks for the info! Good stuff! I was thinking of a tube of the sealant, not a two-pot expoxy! (Sound of hand smacking forehead!

)

Joe, what's this primer stuff it says you have to use with it?

Looks like another $100 to be able to use the stuff.

Or is the primer the part B or something?

The primer is not absolutely necessary... you need the primer if you intend to use it to join 2 materials together as the primary bond.. just the 2 part solution is necessary if you are going to use it for "sealing"
