Installing a mini-split in the US. On the indoor units, the liquid line coming from the unit is 8mm, not 1/4, though it has 1/4 flare fitting. Trying to bend the line into position, I've indented the tube slightly. Arrgh. It is very difficult to find 8mm flare fittings in US, much less 8mm to 1/4 reducers. I've ordered some 8mm to 8mm unions from China which will arrive in several weeks. Can I just ignore this ding, or should I wait for fittings to arrive? Or any other alternatives? Don't want to wait that long for ac this Summer.
Edit: Thanks for comments. I edited the subject and added pictures.
Yes, the OD of the smaller line is ~.315 inches. The brand is Durastar, 18k indoor unit.
Is it necessary to fix this bend?
Can I drill out a 1/4 or 5/16 flare fitting and use that?
This is a diy unit, and refrigerant is not released until I turn the allen screws on the outdoor unit. I intend to do my best to follow rules regarding handling of R410A.
Thanks for any help.
