Poly Processing Company products

For day tanks, an economical alternative to traditional U-vents or fittings. Made of polypropylene, in sizes 1 to 3 inches.

Until now, space-consuming (and expensive) large vents or multiple vents were necessary to meet venting requirements in order to maintain the warranty. Our solution is an 8” mushroom vent, which is available as a complete assembly in a standalone version. This mushroom vent has been used by Poly Processing Company for several years as part of the F.S. 2650 manway cover. The vent now comes with a flange molded into it so that it can be installed on the dome of the tank to give you greater venting capacity. This is a more cost-effective alternative to many other venting systems.
