Joint type/leak help (heat exchanger)


Hi,

UnfortunatelyI've got a leak from the output of the condenser heat exchanger on my Heatline Vizo 24. Please could someone ID what kind of joint this uses from the attached photo as I cant seem to be able to find out using the powers of google (and the installation manual is no use).

Any advice on how to stop the leak would also be welcome!

Thanks in advance.

has some type of pull tab locking the bottom pipe to the top unit. may have 0-rings or teflow seals or other type of method to seal it. may have to get a Pro who knows that unit to drain it and fix and refill it properly.

That is an expansion joint.
The fitting should have an "O" ring that is retained by a clip.

judging by the discoloration of the pipe it must be getting very hot. some o-rings are rubber and better quality ones are silicone and may look like rubber but are rated for higher temps. may need to check into a better grade of o-ring.

RTV no work-ee this time Yuri? Never seen one of those before. It' a Vizo...so I guess it's Asian.

Hey Yuri...did that leaker look like a solder attempt had been made to it?

Looks like somebody smoothed out a solder connection with wet rag.
