Natural PVDF flange fittings are made by Nibco® and part of the Chemtrol® line of premium PVDF pipe products. They are often used to create tight seals as plumbing passes through walls, floors or ceilings. They are also used to connect plumbing lines to valves, strainers, pumps and other pipework components or system equipment with flange style connections. Available natural PVDF flanges come in standard flange and blind flange types in both heavy duty and light duty models. They are manufactured in schedule 80 thickness and are available from 1/2" up to 6" NPS diameter sizes. Available natural PVDF flange fittings come in female threaded or socket type connection styles. They are manufactured from professional grade purity PVDF that is free of added colors or materials to yield natural Kynar PVDF flange fittings that are white to off-white in color. Natural PVDF flanges have significant chemical durability, high service temperature thresholds, are resistant to microbial growth and unaffected by UV exposure. They are approved for handling high purity water, drinking water and consumable materials per ANSI, NSF, FDA and USP requirements.
