• 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 Hi-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 (formerly American Gas Association) to the ANSI LC-1-2005, CSA 6.26-2005 standards.
• Pro-Flex® manufacturers the ONLY CSST fitting and components which are completely reusable. No special tools are required to assemble our fittings.
• All Pro-Flex® CSST flexible gas piping and fittings are quality checked and pressure tested before shipping into the marketplace.
• Pro-Flex® flexible piping is annealed to give better flexibility without altering the strength of the pipe. Pro-Flex® flexible pips will stay in place when formed or bent. Non-annealed pipe, bent after forming, has a much higher chance of stress corrosion cracking.
• We believe in the Pro-Flex® so much that we patented it!...Patent #5,845,946, #5,857,716, #6,102,445
