The core challenge in HVAC/R installation is creating a connection that is permanent, leak-proof, and can endure the harsh realities of high pressure, vibration, and temperature swings. For too long, the industry has relied on imperfect solutions like flaring and brazing. At SmartLock, we solved these problems through engineering innovation. Our technology replaces antiquated techniques, ensuring our HVAC refrigerant fittings are the highest quality solution available.
The Technology Behind SmartLock Refrigeration Fittings
Patented Metal-to-Metal Sealing Technology
The foundation of our superior performance lies in our patented metal-to-metal seal. Unlike inferior refrigeration copper fittings that rely on rubber O-rings—which quickly degrade when exposed to refrigerants and oils—our system uses durable metal ferrules. As the nut is tightened, an internal mechanism forces the ferrule to permanently conform to the tube, creating a zero-leak connection that lasts the life of the system.
The Process Explained
When a technician tightens the fitting with a standard wrench, the metal ferrule is permanently shaped and clamped onto the outer dimension of the tube. This cold deformation creates a lasting, physical bond. This engineered precision eliminates the inconsistent results of human error often seen in brazing and flaring jobs.
Superior High-Pressure and Temperature Ratings
Our commitment to engineering excellence ensures our HVAC refrigerant fittings meet the most demanding specifications in the industry. The structural integrity of the metal-to-metal seal allows for the best burst pressure ratings, up to 9700 psig for 1/4" tubes. Furthermore, our fittings maintain their integrity across an extreme range, from -40°F to 320°F, ensuring stability regardless of the operating environment.
Full Compatibility With All Refrigerants
One of the greatest advantages of our SmartLock refrigeration fittings is their universal compatibility. Due to the inherent stability of the metal ferrule, our fittings work perfectly with every type of refrigerant, including R-717, R-410A, R-22, R-134a, and R-744. This versatility means our refrigeration copper fittings can be used for any job.
The technology inside every SmartLock product is designed to eliminate risk, save time, and maximize system lifespan. Our durable, high-pressure HVAC refrigerant fittings are more than just a component; they are a long-term solution. Ready to experience the innovation of SmartLock refrigeration fittings?
