So I need to make a mitsubishi split system 2.5kw inverter system quick-coupling. Any solutions or ideas on the best way to achieve this?

Cheers

Didn't know that they had quick couplers on those splits, thought that they used flares.

Yes they do have standard flares, but am sure I have seen several quick-coupling solutions to adapt the design to be quick-coupling. The idea would be that in a disconnected system the ***** would remain inside the pipework until it's reconnected.

Thanks, although already have tried their units.

Honestly speaking, I didn't particularly like their attitude when I faced an issue- quite unhelpful and became very defensive.

In addition, their products (while they seem to work ok) should be purchased with caution. If anything goes wrong, you need to go back to them and they can do whatever they like. You have no other real choice.

usually qwik couplers can only be used once,and if you release them they loose gas- 5 min job to pump down and disconnect flares if req

Hence I'm concerned about disconnecting my EcoAir quick-coupling one since there have been issues with people mentioning the seal being deteriorated.

How much does R410a regassing cost these days?

flexi pipes- regassing prices will vary depending on your location, using flexi lines, if you want to relocate the unit, pump it down using the outdoor unit isolation valves, relocate, pressure test,vac and open lines, job done

I used Parker Hydraulic quick release couplings years ago on offshore platforms , they have a special rubber seal I can't remember what it was called but you have to use it in standard couplings and the losses are negligible , less than disconnecting system analyzer hoses.The had to make the complete assembly up and we just told them length required.
