About Mastercool
For more than four decades, Mastercool has built its reputation as a family-owned and operated manufacturer dedicated to delivering precision-engineered tools and equipment for the automotive and HVAC/R service industries. What began as a focused effort to serve professional technicians has grown into a comprehensive product lineup trusted by mechanics, HVAC contractors, and service shops around the world.
Unlike many tool brands that chase broad consumer markets, Mastercool's identity is rooted in professional-grade performance. Every product in their catalog — from refrigerant recovery machines to brake line fabrication tools — is designed with the working technician in mind. That focus on the trades has helped them earn loyalty across generations of service professionals.
A/C Service Tools & Equipment
Mastercool's strongest foothold is in automotive and HVAC air conditioning service. Their A/C recycling service machines — including their well-regarded Arctic Commander R/R/R line — handle refrigerant recovery, recycling, and recharging in a single integrated unit, meeting EPA requirements and reducing shop downtime. These machines are engineered for both automotive and stationary HVAC applications, making them versatile additions to any professional service bay.
For technicians who prefer hands-on manifold work, Mastercool offers an extensive selection of A/C system charging hoses. Built with high-quality materials and precision fittings, these hoses are designed to handle the pressures and chemical demands of modern refrigerants like R-134a and R-1234yf. Pair them with Mastercool's lineup of A/C system pressure gauges for accurate, reliable readings during diagnosis and recharge procedures. Their gauge sets are available in analog and digital configurations to suit different shop workflows and technician preferences.
Brake Line & Tubing Tools
Beyond A/C work, Mastercool has a strong presence in brake system fabrication. Their double flaring tools are engineered to produce leak-free, OEM-spec flares on steel and copper-nickel brake lines. Whether a technician is repairing a rusted line on a daily driver or building a custom brake system from scratch, Mastercool's flaring tools provide the consistency and durability that professional work demands.
