Finding the right connections for your HVAC/R systems shouldn’t be a gamble involving open flames or inconsistent flares. At SmartLock, we have revolutionized how technicians approach refrigerant lines by providing a safer, more reliable alternative to traditional methods. If you are tired of dealing with seasonal leaks and labor-intensive installs, we have the permanent solution you need.
The Best HVAC Flare-less Fittings: Where Reliability Meets Innovation

The Downside of Traditional Flaring
Standard flare fittings are notorious for loosening over time due to extreme temperature cycles and constant system vibrations. We have seen how even perfectly torqued flares can eventually fail, leading to costly refrigerant loss and frustrated customers. By moving away from these outdated mechanical connections, we ensure your installations remain airtight regardless of the environmental pressures.

Unmatched Metal-to-Metal Sealing Technology
Our patented technology creates a permanent, zero-leak seal by utilizing a durable metal ferrule instead of high-maintenance rubber o-rings. We designed this system to handle pressures up to 9,700 psig, providing the highest design pressure range available on the market. This ensures your connections remain secure, even when handling high-pressure refrigerants such as R-410A or A2L.

Eliminating the Need for Hot Work
One of the greatest advantages we provide is the elimination of brazing, welding, and specialty hot-work permits on the job site. With our fittings, you only need standard wrenches to create a professional-grade, permanent connection every time.
