Product Q&A
11 QuestionsQ: My mini split has 1/4 and 1/2 OD lines. Is this how the sizing is rated? I tried to buy copper tubing at home depot and the 3/8 copper tube was ID and was the same as my lineset.
Asked by Curtis 9 years ago
Add your answer
Verified Reply- SupplyHouse StaffYes, refrigerant linesets are listed by pipe OD.
Q: The 1/4" LL x 3/8" SL refrigerant line would require what size diameter conduit to run the lines underground?
Asked by jj 11 years ago
Add your answer
Verified Reply- Supplyhouse StaffApprox. 2.5", for both lines w/insulation.
Q: Will this lineset work with a Mitsubishi Mr. Slim heat pump? Models: MUZ-FE09NA-1 (condenser) + MSZ-FE09NA-8 (head unit) or MUZ-GE09NA (condenser) + MSZ-GE09NA-8 (head unit)
Asked by Mike 13 years ago

If the Mitsubishi has flare fittings of 1/4 supply and 3/8 return it will work just fine. My older mini splits and my new Sanyo mini splits also use the same line set.
Q: Does this line set ship with caps installed on all ends to protect from contamination? We will be shipping them to construction sites and need to keep dirt and debris out. Thanks
Asked by Jeremy 13 years ago
Add your answer
Yes, they cap the ends.
Yes, the sets I ordered did-- red plastic plugs on both ends.
Yes, the ones I received had a plug type cap that was fairly secure.
yes
Yes, my line set was capped at both ends.
The four line sets I ordered two years ago all came with plugs to prevent dirt from entering but I don't know if they do now.
Q: How do i take the air out of the line?
Asked by Beekmansup 14 years ago
Add your answer
You will need a vacuum pump with at least one hose that connects the pump to the service port on the mini-split. I would draw the system down for at least half an hour before releasing the vacuum, then releasing a small amount of refrigerant into the system and checking for leaks using a soapy bubble solution at each of the flared fittings. The preferable method is to use the vacuum pump and a set of gauges so you can measure the degree of vacuum, then lock down the gauge set closed and wait to see if any vacuum bleeds off. That will determine whether you have any leaks in your flared connections between the indoor wall unit and outdoor condenser/compressor.
Q: Is this line set compatible with the Ramsond Model 74GW2 24000 BTU SEER 13 Mini Split Ductless Air Conditioner with Heat Pump?
Asked by Mook 14 years ago
Add your answer
Verified Reply- PexSupply StaffThis line-set will work as long as the unit requires a 3/8" x 5/8" line-set.
Yes it is compatible,but inspect the flares to see if they are perfect. If not, cut them off and re-flare. Good choice!
No its not. You need a line set of 3/8 inch for the gas and 1/4 inch for liquid. Your unit should have been supplied with a line set. Look for a line set pre-flared or you will need to rent or borrow a flare tool.
Q: I need a 15foot, 1/4"LL, 5/8"SL line set for a new 1.5T R410A Goodman central air system install. The units are designed for brazed line set connections. Will This Mini-split, flared line set be acceptable to use in my system? I.e. can I cut the flared ends and directly braze the connections? Thank you.

Verified Reply- PexSupply StaffWe don't see any problem with this, although it may be easier to purchase a brazed line-set if you are able to find one.
Q: What is the tubing material? What is the minimum bend radius of the line?
Asked by Chuck 15 years ago
Add your answer
Verified Reply- PexSupply StaffThe tubing is made out of level-wound copper. The minimum bend radius is not a listed spec. We would estimate that it would be about 7 times the outside diameter of the copper.
Why not use bulk coil copper tubing I wholesale to Dealers and contractors, ONLY, has a very high PSI rating, all sizes the wall thickness is 0.30. I sell a lot of it to Boat shops for hydraulic steering and I am sure this application has no were near the PSI as that, ¼” is like 1800 PSI 3/8” 2700PSIit comes in 25’ & 50’ coils and maybe a whole lot cheaper, I don’t have a silver solder supplier.
Q: Does this line set work with LG LA240HSV?
Asked by tzalud 15 years ago
Add your answer
Verified Reply- PexSupply StaffYes, it does.
Q: Are there valves or check valve fittings at either end to preclude escape of refrigerant during connection of the line set?
Asked by Misterfixit 15 years ago
Add your answer
Verified Reply- PexSupply StaffLine-sets do not include refrigerant. Refrigerant will not flow through them until both ends are fully hooked up. The outdoor unit of the mini-split system will hold all the refrigerant until the system begins to operate.
