DETROIT, Mich. — Polypropylene vent pipe has never been better positioned to become the top choice for venting ANSI Category II and IV gas-burning appliances in North America. For those who have not yet fully embraced the product, DuraVent’s new locking clamp for its Polypro vent pipe just might seal the deal.
The clamp, which can be used on both new and existing PolyPro installations, is made of 430 stainless steel and comes semi-installed on the female end of every piece of PolyPro pipe and fitting. A single stamped part, the clamp seamlessly incorporates a hose clamp and a series of metal “teeth” that encircle the pipe and hook onto a gasket extrusion (seat) on the female end of the pipe.
