The RCS fitting system has revolutionized the installation and servicing of refrigerant piping. Its press-on style eliminates the need for torches and brazing, making the process significantly faster—twice as fast as traditional brazing. Additionally, there is no need for nitrogen purging or displacing oxygen during installation. The fittings are sleek in design and have been proven to handle maximum working pressure, allowing for easy installation with minimal effort. With the increasing use of new A2L refrigerants, these coupling systems are likely to become even more prevalent. - Shane Q.

Thank you for creating this product. I have been using the RSC fittings and copper for roughly three years, and I have been very impressed with the quality of these products. There is a small learning curve, but once you get the hang of it, it works great. I have yet to experience a fitting failure that wasn’t my fault (Note: always clamp evenly and avoid using too much sealant).The ability to use bendable copper allows for a 20-foot run with multiple bends and only connectors at the ends, which saves time and reduces potential leak areas. I would highly recommend this for anyone installing VRF systems. There’s no need for purging, and there’s no risk of contaminants entering the systems due to brazing. - Steve B

I’ve used the RCS system now 5 years. My experience with the RCS couplings has been great. Its basic concept makes it rather easy to teach someone in little to no time. It has saved me many hours on the job. I personally if installed properly have never had a leaking coupler yet! I would recommend this product to anyone in the HVAC industry. – Jason G
