When it comes to refrigerant line connections, one question often arises: "Do copper HVAC fittings leak?"

Do SmartLock Copper HVAC Fittings Leak?

Engineered for Absolute Integrity
Our patented Metal-to-Metal Sealing Technology. Unlike conventional quick-connect fittings or AC line fittings that rely on rubber o-rings – materials prone to degradation when exposed to refrigerants, oils, and temperature fluctuations – our flareless fitting system utilizes robust metal ferrules. Our copper HVAC fittings boast a verified 0-ounce annual leakage rate.

The Science Behind a Permanent Seal
The mechanics behind our leak-proof guarantee are straightforward. As our outer nuts are tightened with standard wrenches, an internal mechanism applies immense pressure, permanently indenting the metal ferrule onto the tube or valve. This creates a seal with unmatched integrity, designed to hold up to pressures of 9700 psig and maintain stability across a wide temperature range of -40°F to 320°F. This superior engineering means that the connections made are secure and permanent.

Driving Success Through Reliability
For your business, offering these flareless ac hose fittings translates directly into benefits. By supplying a quick-connect product that virtually eliminates leaks, you drastically cut down on customer complaints and product returns. This also increases contractor confidence, knowing their installations are secure and permanent.
