The 75ft MRCOOL DIY Coupler Kit (DIYCOUPLER-1412K75) offers a convenient solution to connect three line sets together, allowing you to extend the length of your MRCOOL DIY line set. You can combine three 16ft line sets, three 25ft line sets, or even mix and match 16ft and 25ft line sets to reach the desired length. If you only need to connect two line sets, we also offer the 50ft Coupler Kit, available for purchase on our website.

This DIYCOUPLER-1412K75 kit includes two DIYCOUPLER-14 and two DIYCOUPLER-12 (1/4" x 1/2" couplers), along with 75 feet of communication wire, ensuring everything you need for a seamless installation. To set it up, simply disconnect the pre-attached 25-foot wire from your indoor unit and replace it with the new 75-foot wire for an extended reach.

Designed for use with 9,000, 12,000, and 18,000 BTU indoor wall units, this coupler kit provides flexible options for various configurations. For larger systems, such as 24,000 or 36,000 BTU indoor wall units, we also offer additional coupler kits. Whether you’re a DIY enthusiast or an HVAC professional, the 75ft MRCOOL DIY Coupler Kit ensures a quick and efficient installation process to meet your HVAC needs.
