seals for Radiators

[Thunderchild]

I'm putting my radiators back, I have an olive fitting with a swivel nut on the rad that fits onto a fitting with an internal cone, I take it i do need a rubber washer between the two and not ptfe tape on the thread as that won't do anything

Even ladies can do it ....

yea all done now, room steadily getting warmer after i worked out how to refire the boiler

mind you they forgot to mention the rubber washers, infact I'm not impressed with the video, the PTFE tape is not the best option, infact a mere bodge

Where would you fit a rubber washer .... ?

I'd certainly keep an eye on that valve if you have'nt used PTFE tape, or a sealing paste, otherwise you will be asking how to fit plasterboards to ceilings.

as I said in the original question, the rad fitting is an olive that sits into a chamfered fitting, you can't use PTFE tape (infact there are some bits of old rubber washer left on some of the rads) as ptfe tape is for seals on threads, the seal is infact on the inside of the fitting between two surfaces. The fitting is a swivel nut, putting PTFE tape on it will just alow water out of the back of the nut as the mating surfaces have so deal so the water will leak into the nut and out the back.

PS I work with automotive ratiators and air conditioning daily

Dry fit that type.
Some have integral seal tho as part of connection.
Latest type aren't like that at all.
