Festo food-compliant tubing/fitting combination

The PUN-H-F tubing and NPQR stainless-steel push-in fitting product combination from Festo is designed to ensure compliance with food safety requirements for manufacturers of food and packaging machines.

The PUN-H-F food-compliant tubing meets the standards for use in the food industry according to Regulation (EC) 1935/2004 and FDA 21 CFR 177.2600. Together with the NPQR fittings, it can be used in the food and packaging industry, particularly in places where it might come into contact with food.

The kink-resistant 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 material used prevents hydrolytically induced cracking. The black version is especially UV-resistant and thus also suitable for use outside of enclosed buildings. The ‘natural’ colour variant is suitable for applications with gaseous oxygen as the operating medium.

The push-in fitting also complies with Regulation (EC) 1935/2004 and the materials are listed to FDA 21 CFR. It is additionally certified to NSF 169.

The large number of variants, threads and tubing sizes makes it suitable for many different applications. Assembly is easy and works by simply plugging and unplugging the tubing. Leaks are prevented by a chambered O-ring that is securely held in place. The food-compliant design reduces edges where dirt could collect. This makes the push-in fitting easy to clean.

In applications where fittings are subjected to intense heat, the NPQH metal fitting can be used, which is also food-compliant, heat-resistant up to 150°C and suitable for high pressures.
