Built to Last PolyPro is a 2.2 mm thick, polypropylene vent pipe for use with ANSI Category II and IV gas-burning appliances, including high efficiency water heaters, condensing boilers and warm air furnaces. Improved Locking System PolyPro uses a new locking system featuring a locking tab on the male end of the pipe and locking clamp that ensures a secure connection at pipe joints.
