Stainless in aluminum

More specific to the ability to seal, no. Anti-oxidant compound is much like a thin grease rather than a sealant. I imagine you snow belt guys have concerns over water in rigging swages.

So do you recommend putting nothing into a Norseman terminal?

[edwardc]

My formula has always been tefgel on the threads to prevent galling, and a flexible sealant, such as 3M 4000-UV, inside the cone/wire/collar assembly to prevent water intrusion.

In temperate climes, yes. I'd assemble them commando style. In areas subject to freezing (of which I have zero experience so weigh this accordingly) I'd consider a way to keep water from pooling inside the terminal.

+1 to this. If I recall, a local rigger suggested assembling the fitting to form the wire (with your thread locker or tefgel) and then reassemble the fitting with sealant.

[hanleyclifford]

So if I understand this correctly, the goal is tight encapsulation to keep water from running down the wire and getting into the fitting. Would 5200 be suitable?

[edwardc]

IMHO, 5200 is the wrong thing to use. You don't need bond strength, just sealing. 5200 is great for bonding things you never want disassemble again.

[marthur]

If you want to go with polyurethane, use 4200.

So I was thinking about this last night and wondered, why isn't there a problem with frozen water in the pockets of swaged terminals? Is there, in fact, a problem with freezing in the pockets? I don't know, and I'm curious....

Russ? Mo? What's the high latitude experience/opinion?

My question, too. Is it better to let the water flow thru a swage and exit or should the attempt be made to "encapsulate" the fitting, and possibly risk containment of water in the fitting should partial failure occur?

Not a problem in our area but cracked swages due to freezing is a known problem. Unfortunately typical machine swages with their open ends facing up (such as at the turnbuckles) are water catchers without some sort of seal.

I would have expected this but I've never read about it, and my rig is down for the winter..... I would think it's nearly impossible to 'seal' 1x19 stainless wire, as the water is running down the rigging. You could seal the outside, but never the interior surfaces of the wire. Maybe with a very low viscosity potting.... Curious.

30 ~ 40 years ago all that was done was to put a schmeer of silicone around the wire where it enters the swage.
