MRCOOL Lineset for DIY 5th Gen Mini Split Systems - R-454B

MRCOOL Lineset for DIY Mini Split Systems - R-454B

The MRCOOL DIY Line Set is designed for installation of all MRCOOL DIY ductless mini splits. These linesets are compatible with the MRCOOL DIY 5th Gen Single Zone, MRCOOL DIY Multizone, and Central Ducted Mini Split Systems. The included 3/4 in. UV Protective Insulation Sleeve provides extra protection against sun damage, weather erosion or destruction from animals, etc.

If one DIY Ductless Split System Line Set isn't long enough, you can combine two to three DIY Ductless Split System Line Sets together using a coupler to increase the desired length of the line sets (Up to 75ft).

The line sets connect the condenser outside to the indoor air handler. The MRCOOL DIY Quick Connect Line Set is pre-loaded with an R-454B refrigerant. It uses Quick Connect Fittings that are specifically designed for installing both Mr. Cool DIY Single and Multi-Zone Split Systems.

Since these are No-Vac linesets, they easily plug into the outdoor condenser and Wall Air Handler inside. No cutting, brazing, vacuuming, or charging required.

They are also kink-resistant and made to be easy to bend during installation.

The linesets come in 16ft, 25ft, 35ft and 50ft options in one piece. The 35ft and 50ft linesets include a longer DIY Pro Cable communication wire in the box. The 75ft lineset consists of a 50ft + 25ft + coupler kit.

The 1/4" 3/8" lineset is compatible with the 6K, 9K, and 12K air handlers.

The 1/4" 1/2" lineset is compatible with the 9K, 12K, and 18K air handlers. (1% more efficient than the 1/4" 3/8")
