sealing compression fittings

[Bluedrifter]

Hello,
I've been revamping my bathroom and have used some 15mm compression fittings under the floor which is to be tiled. All the joints are fine with the gravity feed system, but I want to add a combi boiler at a later date. Is there something I can use on the olives of the joints, just to make double sure there won't be any leeks with the higher pressure?
Thanks for any advice.
Adrian

Hi there,

Theres a few options.

Jointing Compounds, Boss White / Blue, Hawk White, or another alternative is Loctite 55 string.

your asking for trouble having a comp fitting that is not readily accessable, remove and replace with solder fittings.
