What Is a Pro-Flex Female Fitting?
A Pro-Flex female fitting is used to terminate a section of Pro-Flex CSST and provide a female threaded connection for a compatible gas-system component.
The fitting forms part of the Pro-Flex CSST connection system and allows flexible corrugated stainless steel tubing to transition to threaded valves, fittings, piping, or equipment connections where the required configuration calls for a female connection.
Select the fitting according to the nominal CSST tube size being installed.
