Integraflow supplies a range of Metric DIN Nitrile Seals, designed for DIN 11851 hygienic unions on metric outside diameter stainless steel pipework. Nitrile (NBR) is a durable, cost-effective gasket material with excellent resistance to oils, fats, and greases, making it especially suitable for hygienic process systems in dairy, edible oil, and food and beverage industries.

These gaskets sit between the liner and ferrule, compressed by the DIN nut to form a reliable, hygienic seal that holds up under typical CIP (Clean-in-Place) regimes and moderate thermal cycling.

Key features:

• Compatible with DN10 to DN150 metric OD stainless steel tubes

• Strong resistance to animal and vegetable oils, mild cleaning agents, and abrasion

• Working temperature range: -30°C to +120°C

• Available in black or white food-grade nitrile

• Compliant with FDA standards, optional USP Class VI versions available

• Fully compatible with Integraflow’s Metric DIN Liners, Ferrules, and Nuts

Typical applications:

• Dairy processing and milk transfer systems

• Edible oil bottling lines

• Food and beverage manufacturing

• Hygienic piping systems where fat/oil resistance is critical

All Metric DIN Nitrile Seals are batch traceable, manufactured to DIN 11851 dimensions, and available for fast UK-wide dispatch from Integraflow – your hygienic sealing partner.
