Flexible Gas Piping by Pro-Flex®

At Pro-Flex, our perspective on our Corrugated Stainless Steel Tubing (CSST) is one of unwavering confidence and pride. We’ve engineered our CSST to be a game-changer in the realm of gas piping installations for natural gas or propane gas appliances. Our commitment to innovation is evident in every aspect of our product, aimed at making the installation process quicker, easier, and more efficient than ever before.

The hallmark feature of Pro-Flex CSST is its unparalleled flexibility. Unlike rigid piping methods that demand meticulous planning and intricate maneuvers, our CSST bends and adapts effortlessly to any layout or configuration. This flexibility not only saves valuable time on the job but also minimizes the need for additional fittings and connectors, thereby reducing the risk of leaks and ensuring a smoother, more reliable gas delivery system.

Safety is at the forefront of everything we do. Constructed from premium-grade stainless steel and featuring a robust corrugated design, Pro-Flex CSST offers exceptional durability and resistance to corrosion. This design not only enhances the longevity of the system but also provides added resilience against external factors such as seismic activity or structural settling. With Pro-Flex CSST, professionals can trust that they’re installing a gas piping system that prioritizes safety, reliability, and ease of installation above all else.
