A common challenge we often hear about in the food and pharmaceutical industries is finding a ducting solution that’s both flexible and certified for food contact, without compromising on strength or hygiene. That’s exactly why we stock the Protape PUR 330 FOOD range. This food-grade polyurethane ducting is designed to handle everything from flour and sugar to milk powder and cereals, all while maintaining high flexibility and compliance with strict industry standards.
We’ve supplied this hose to clients across the food manufacturing, bulk handling, pharmaceutical, and healthcare sectors. It’s especially popular for use with packaging machines, mixers, dryers, and bulk-bag filling systems, as well as in cleanroom ventilation setups.
The ducting is made with a spring steel wire integrated into the wall, allowing for strong shape retention while still being easy to compress and route. It’s odourless, tasteless, and manufactured in compliance with GMP EC 2023/2006, so customers know it meets the latest hygiene and materials safety regulations.

What We Like Most
This ducting stands out in our range thanks to its full compliance with both EU and FDA food contact regulations. But it’s not just about paperwork, it performs just as well in the field.

- Food Safe – Fully approved to EU 10/2011, EC 1935/2004, and FDA 21 CFR 177.2600.
- Odourless & Tasteless – Won’t contaminate food or pharmaceutical products.
- Flexible & Compressible – Can be compressed 3:1, making it easy to transport and install.
- Microbe & Hydrolysis Resistant – Excellent for dry bulk products and powder handling.
- Wide Chemical Resistance – Stands up to oil, mild chemicals, and cleaning agents.
- Temperature Range – Works from -40°C up to +90°C (short bursts to 125°C).
One customer in the dairy sector switched to this hose after issues with brittleness in colder temperatures, this model stayed flexible and performed consistently, even in chilled environments.
What Could Be Improved
Although this ducting performs exceptionally well, here are a few things we’ve noted when helping customers choose the right product:
- Not Suitable for Liquids or High Pressure – This hose is best for dry bulk and ventilation, not pressurised systems or liquid handling.
- Wall Thickness (0.6mm) – Great for flexibility, but may need care in handling to avoid kinks in tighter bends.
- Premium Product = Premium Price – While it’s worth the cost for regulated industries, it may be over-specified for general-purpose ducting needs.
