The 14 Inch Manway (PE) Threaded, Non-vented is a Snyder Industries polypropylene lid assembly - a black, threaded closure sized for a 14-inch threaded manway. It measures 15.4 x 15.4 inches across the flange with a 12.6-inch overall height and weighs about 8 pounds. Non-vented means it seals closed with no built-in air path, so any venting has to come from a separate fitting elsewhere on your tank.
What it fits
This is a Snyder 14-inch threaded manway. Manways are not interchangeable across brands or opening sizes, so confirm your existing collar is a matching Snyder 14-inch threaded pattern before ordering. The black polypropylene body will not corrode the way a metal cover can.
Install
Thread the manway down onto the tank collar by hand until it seats fully and squarely. Because it is non-vented, keep it paired with proper tank venting so pressure or vacuum never builds under the lid during fill and draw.
