Food-safe tubing introduced for assured regulatory compliance
Mike EdwardsProducts festo food-safe NPQR fittings PUN-H-F tubing
Festo has introduced PUN-H-F polyurethane tubing with push-in NPQR stainless steel fittings said to provide a suitable combination for the food and packaging industry, especially where food contact may take place.
The PUN-H-F tubing and NPQR fittings meet the requirements for Regulation (EC) 1935 / 2004 and FDA 21 CFR 177.2600, making them an excellent option for a wide range of common applications, the company says.
The tubing is equally appropriate for use in food or non-food zones, with kink resistance said to provide for easy installation in any system. This tubing is resistant to hydrolysis and microbes, making it suitable for environments with high moisture or with water at temperatures up to 60°C.
The composition of the material used prevents hydrolytically induced cracking which can result in premature failure. Additionally, the black PUN-H-F variant is UV-resistant, making it suitable for outdoor use while the “natural” colour variant can be used for applications with gaseous oxygen as the operating medium.
NPQR fittings additionally are certified to NSF 169. Joining of the tubing to the fitting is easy, the company says – simply push the tubing into the fitting for a secure, seal tight connection. The food-compliant design of the fittings minimizes edges where dirt could collect, it adds, making them very easy to clean.
