leaking stainless steel sink outlet
 

please, what is the correct sealant to use for the (steel) 1.5in
outlet to a standard kitchen stainless steel sink?

Mine developed a leak 2 months ago after years of no trouble. I
refitted it sealing with Bosswhite & it now seeping again.

What is the correct sealant/method?

many thanks for any help.

Silicone rubber.

Disassemble
Smear with silicone goo.
Do up finger tight or even less.
Wipe of excess carefully.
Wait a day
Do up tight.

The silicone will forme a perfectly matched rubbery gasket, which will
be think enough to tighten down properly after curing.
I learnt this trick from a plumber - he threw all the washers way, and
simply used silicone on everything. None of his joints, or the ones I
made using his technique, have leaked.

I take it you're putting the sealant above the sink but below the fitting?
In other words, sandwiched by the top of the sink and underside of the
fitting? In which case, use hemp with the Bosswhite laid out in the form of
a ring, or use silicone sealant if there's no washer provided. Or get a
washer.

Another contradictory suggestion

I used something called "plumbers putty". It was on the shelf next to
Boss White and Hemp. It is like a sticky version of plasticine. I
rolled a "sausage" of the stuff (after several attempts), cleaned all
surfaces as far as possible, checked the existing seals were not
fractured or deteriorating, placed the sausage over the "parts" that
were to meet, screwed it all back together (hope this makes sense),
cleaned off excess with a modelling knife. Neat job, no leaks. Took 30
mins in total being careful.

Whatever material you use I think it needs to flexible so frame
sealant is out.

Thats stuff IS good unless there is mechanical movement than can
compress it ouit of the joint, and then flex back to open up a leak.

Thats the beauty of the silicone. It forms a perfect rubber gasket if
used appropiately.

And ....

Eventually plumbers putty dries out and crumbles and leaks (that's
what I experienced) - which is why I had to replace it in the first
place ....
