Piping coupling

[Mohammed Nofal]

the piping in most cases in HVAC applications is connected by soldering or brazing .. i want to ask if it can be connected by a coupling ? what is the type of coupling is suitable for HVAC application also if anyone know a supplier for it

Hi Mohammed and welcome to the forum.
The other type of connection is called a compression fitting and can be a flare or some type of threaded fitting which will seal two faces to prevent gas leakage. One other type is a shaft seal for a rotating shaft. There are a myriad of suppliers for different types of flare fittings/couplings - best check them out on google. Why do you ask this question - do you have a particular application?

Thank you Tesla and hope to be on of the active members in this forum
actually my friend i'm from PETRA company which is an HVAC OEM , now i'm using brazing and flare for condensing unit connection but as you know flare is not applicable with large diameter i need to find a suitable coupling for that if you have any suggestion

That's a really cool place I went there with in 2008 and I liked The Monastery best. Sorry I don't have any suggestion for a large pipe. I have seen a new coupling system on large water pipes where they bolt together like a clamp arrangement. I'm sure if there is something someone here will be able to help.

Many compressors use rotalock connections, i'm sure they could be used to join pipe too.

vulcan lok rings- never used em, some swear by them others hate them, not gonna start using em until manufacturers approve them

The larger the pipe the better the need for good brazing.
