Is the 90Â° angle plug connector, type R 4 NSF, safe for continuous use with hot drinking water up to +150Â°C and does it meet NSF/ANSI 61 requirements?

Yes. The 90Â° angle plug connector, type R 4 NSF Format is specified for use in the food industry including cold and hot drinking water, has an operating range up to +150Â°C, and is made without plastic components (nickel-plated brass) with Viton seals. Viton seals are FDA-approved for food contact and the product is listed to NSF/ANSI 51 and NSF/ANSI 61 standards. Therefore it is suitable for continuous use with hot drinking water up to +150Â°C and meets NSF/ANSI 61 requirements.

Can the 90Â° angle plug connector, type R 4 NSF, be used with aggressive cleaning chemicals without degrading seals or nickel coating?

Yes. The 90Â° angle plug connector, type R 4 NSF, is suitable for use with aggressive cleaning chemicals. It contains no plastic components, is nickel-plated brass treated by a special chemical process, and uses Viton seals (FDA food-contact approved) that offer high resistance to detergents and many aggressive chemicals. Its operating range (â20Â°C to +150Â°C) and certifications (NSF/ANSI 51 and 61) further support suitability for food-industry cleaning regimes. As with any application, verify chemical compatibility for specific agents and concentrations and consider operating temperature and pressure limits (16 bar, vacuum 0.99 bar).

Does the 90Â° angle plug connector, type R 4 NSF, comply with FDA food-contact approvals for Viton seals?

Yes. The 90Â° angle plug connector, type R 4 NSF, uses Viton seals that are stated as "approved for food contact by FDA" in the product description. The fitting is explicitly designed for the food industry, meets NSF/ANSI 51 and NSF/ANSI 61 standards, and the specified operating conditions (â20Â°C to +150Â°C, 16 bar) are compatible with typical food- and beverage applications. Therefore the Viton seals on the 90Â° angle plug connector, type R 4 NSF, comply with FDA food-contact approvals.
