Mineral Oil & 5200?

Cool... never heard about the antifreeze fill before.. good to know..

You can find mineral oil in just about any supermarket in the health section. People take it as a laxitive. Usually about $2.50 a bottle. Besides using it as the liquid in a compass it's also used as the fluid inside a liquid filled sump pump. Very high dielectric strength.

I've used sun tanning oil in a pinch, worls just fine

The only problem you may have is if the ducer scatches the 5200 then the oil can get in the 5200 and break it down chemically. I have seen 2 ducers where the mineral oil was leaking out from the seal area and when the owners took them off the 5200 was deteriorating.

But I know of 5 others with the same set up and they have not had a problem.

I'm gonna coat the inside of the well including the 5200 bead around the bottom w/a DAPCO latex sealer...should isolate oil from 5200

Capt Pete...I think they don't want you to set the ducer in 5200 which isn't what I'm doin here...it'll be suspended in the oil...the 5200 is adhesive/sealer for the pipe/well only, so I think it'll be OK...

And the ethyl glycol anti-freeze concerns me more than the mineral oil in terms of breaking down the 5200 over time...thanks for the suggestion and I'll use as plan B, but will forge ahead w/ min. oil til it poofs in my face...LOL!!...

Hey REEL, just brain storming here....what about mixing up a little resin to attach the pipe instead of 5200....no worries then.

Actually I was thinking along similar lines. Why not just epoxy the pipe in place? After all, it's the 'ducer (and the cost of it) that you're worried about being in the wrong place. Granted, the pipe will not be as easy to remove with epoxy as with 5200, but a hammer and a mini-grinder will make short work of it if it does need to be moved. And the epoxy is completely impervious to mineral oil after it's cured. As a safety net you could always run a bead of rtv around the outside bottom of the pipe where it meets the hull once the epoxy is set up.

Randleman & Destroyer...Pobabaly should have done that, but she's been set in 5200 for several days now...I'll coat w/some sealer I just picked up and try 'er that way...if this DOESN'T work, I'll cut it out and epoxy it back in...

5200 is nearly bullet proof once cured
