Integraflow supplies precision-engineered Metric DIN PTFE Seals, designed for DIN 11851 hygienic unions used with metric outside diameter stainless steel tube systems. PTFE (Polytetrafluoroethylene), often known by the brand name Teflon®, is chemically inert, non-stick, and highly temperature-resistant — making it ideal for aggressive CIP chemicals, high-purity applications, and sterile environments.

These seals are seated between the male liner and ferrule in DIN unions, ensuring hygienic, leak-tight performance in demanding process systems.

Key features:

• Designed for DN10 to DN150 metric OD tube sizes

• Outstanding resistance to chemicals, acids, solvents, and aggressive CIP media

• Stable at temperatures up to +260°C

• Non-stick surface ideal for sticky or high-purity product contact

• Available as solid PTFE gaskets or PTFE envelope seals (with EPDM or silicone core)

• FDA and USP Class VI compliant options available

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

Applications:

• Pharmaceutical and biotech manufacturing

• Chemical and solvent handling systems

• Food production with reactive or sticky ingredients

• CIP/SIP systems requiring inert and thermally stable materials

All Metric DIN PTFE Seals are fully traceable, machined to DIN 11851 dimensions, and available for fast UK-wide dispatch from Integraflow – your expert supplier for hygienic sealing in aggressive applications.
