Your installation just got dramatically faster. The MRCOOL No-Vac Quick Connect Line Set transforms what used to take hours into a streamlined, efficient process that saves you valuable time on every job. Pre-charged with precise R-454B refrigerant at 1.94 ounces, this innovative line set completely eliminates the traditional vacuuming and flaring steps that slow down installations. Whether you're a professional contractor juggling multiple jobs or a skilled DIY homeowner tackling your own HVAC upgrade, you'll appreciate how this system cuts seven installation steps compared to conventional line sets—getting your climate control up and running faster without compromising quality or performance.

We've engineered this line set with real-world installation challenges in mind. The kink-resistant design means you can bend and route the lines through tight spaces without worrying about damaging the refrigerant flow. The leak-proof construction gives you confidence that your system will maintain optimal refrigerant levels for years to come. You're getting robust 3/4" Gator-Flextra insulation sleeve protection that shields your line set from UV sun damage, harsh weather erosion, and even destruction from animals and rodents—crucial protection whether you're running lines across rooftops or through crawlspaces. The user-friendly screw-on quick connect valves make hookup incredibly simple, even in confined mechanical spaces.

This isn't just any line set—it's specifically designed for compatibility with your MRCOOL system. It works seamlessly with MRCOOL Gen 2 Central Ducted Series (24K, 30K, 36K, 48K, and 60K Systems) and MRCOOL VersaPro Gen 2 Series (18K, 24K, 30K, 36K, 48K, and 60K Systems). Need more length? You can connect two No-Vac Quick Connect Line Sets together using a coupler to reach exactly where you need to go. Available in four convenient lengths—15 ft, 25 ft, 35 ft, and 50 ft—you can choose the perfect size for your specific installation without excess waste.
