Q: How does Pro‐Flex® vary from other CSST systems?
- Pro‐Flex® fittings are easy to assemble/install. No special tools are required and no flaring is required.
- Our fittings are THE ONLY DUAL SEALED FITTINGS FOR ADDED SAFETY! Our proprietary High‐Temperature Gasket and Silicone O‐Ring will withstand extreme heat and cold temperatures and has been tested for longevity. All fittings and component parts are certified by CSA to the ANSI LC‐1‐2005, CSA 6.26‐2005 standards.
- Pro‐Flex® has the only CSST fittings and components that are reusable.
- Pro‐Flex® flexible piping is annealed to give better flexibility without altering the strength of the pipe. Pro‐Flex® flexible pipes will stay in place when formed or bent. Non‐annealed pipe, bent after forming, has a much higher chance of stress corrosion cracking.
- Pro‐Flex® CSST is sold along with an installation manual which includes all information needed to install Pro‐Flex® correctly. Unlike other CSST systems, one is not required to become certified to install this product. By reading and understanding the installation manual and signing and mailing the qualified installer card back to Pro‐Flex®, the installer is then qualified to use this product.
