MRCOOL 75ft Coupler Kit for DIY Line Sets 24K, 36K & 48K Air Handlers - 3/8" x 5/8"

With the 75ft MRCOOL DIY Coupler Kit, you can connect three line sets together and extend the length of the lineset. You can add three 16ft linesets together, three 25ft linesets together, or a combination of 16ft and 25ft linesets together.

The DIYCOUPLER-3858K75 product includes two of the DIYCOUPLER-38 and two of the DIYCOUPLER-58 (3/8" x 5/8" coupler) with 75 ft of MC-5 Communication cable.

To install the coupler kit, just disconnect the 25 foot wire pre-attached to your indoor unit and replace it with the new 75 foot wire. This product is intended for use with 24,000 or 36,000 BTU indoor wall units, but we also sell the coupler kit for the 9,000, 12,000, and 18,000 BTU indoor wall units.

very quiet

I recently upgraded to the Mr Cool Mini Split and I'm amazed! The team made the process seamless from start to finish. Installation was a breeze, and now my home is consistently comfortable. The sleek design blends perfectly with my decor, and I can hardly hear it running. It's definitely a game-changer for my home comfort!
