Masterflex SE has introduced the Master-PUR DualFlow 1.6 Food A, a spiral polyurethane hose for hygiene-critical applications in the food, pharmaceutical and biotech industries. The hose incorporates a thermoplastic inner lining formed as a seamless, edge-free surface along the flow path. According to the company, this geometry is designed to optimise flow and sliding behaviour, facilitate thorough cleaning and limit the formation of deposits in conveying and production steps. The solution is compliant with Regulation (EU) No. 10/2011, including all amendments, and with FDA 21 CFR § 177.2600 and § 177.1680, supporting its use in processes that require verified food contact conformity. By eliminating discontinuities on the inner surface, the DualFlow concept targets common hygiene risks associated with spiral hoses such as material residues, biofilm development and cross-contamination, which can lead to batch contamination and process inefficiencies. The company positions the introduction as a contribution to process reliability where high hygiene standards and consistent media flow are required.
Hygienic design and flow behavior
The Master-PUR DualFlow features a thermoplastic inner layer engineered to reduce turbulence points and retention zones. The seamless, edge-free surface is intended to simplify cleaning routines and help prevent bacteria traps in demanding environments such as dairy or pharmaceutical production. As described by the company, the result is the avoidance of material residues, mitigation of contamination risks and sustained performance in production and conveying processes.
"Hygiene starts on the inside with DualFlow. Our food-safe polyurethane hose is a technology-based market innovation for modern food production. Cross-contamination? Biofilm? Residues? A risk! If the hose solution is outdated, so is the process," said Marc-Julian Ott, Segment Leader Food/Pharma at Masterflex Group.

DualFlow series and customization
The Master-PUR DualFlow from Masterflex SE marks the start of a broader DualFlow series. The manufacturing approach enables the combination of different materials in future variants, allowing configurations tailored to customer-specific process requirements and industry standards. Companies can collaborate with Masterflex specialists to develop a customised DualFlow system aligned with their application parameters.
According to the company, interested parties may request a sample of the food-safe polyurethane hose or seek expert advice. Masterflex describes itself as a global market leader and an experienced development partner for hose systems.
