A\C build question

[UpNorth]

Hi all,

Spent an « interesting » morning fitting/measuring hoses in the footbox for A\C.
At this point my question is: Do you put sealer on fitting threads? if so, what? Tefflon tape? Liquid sealer?

TIA

There should be green o-rings and use the refrigerant oil in the white plastic vial to assemble.

Ok but nothing on threads?

No sealer required.

X2 on the answers you received. Those fittings seal on the O-rings. Not the threads. No thread sealant. One hint. Be very careful when pushing the connections together. It's not hard to nick or cut those green O-rings. Then you know what will happen. :(
