What Is a Pro-Flex Male Fitting?
A Pro-Flex male fitting is used to terminate a section of Pro-Flex CSST and provide a threaded transition to compatible gas piping components.
Each model is matched to a specific nominal CSST tube size and incorporates the MIP and FIP connection sizes identified by Pro-Flex. This provides a defined transition point between flexible corrugated stainless steel tubing and threaded gas-system components.
Select the fitting according to both the CSST tube size and the required threaded connection configuration.
