Fittings coated with PFA
Hygienic, highly resistant & diffusion-tight
When the highest demands are placed on chemical resistance, purity and process reliability, they are the perfect solution.
Whether as threaded fittings, with TriClamp connections or milk pipe threads (DIN 11851) – M+B Fluid offers a wide range of robust stainless steel fittings with high-quality PFA internal coating for applications in the chemical, pharmaceutical and food industries.
The perfluoroalkoxy (PFA) coating is particularly resistant to aggressive media such as acids, alkalis, solvents and chlorides, while also being stable at high temperatures up to +260°C. The smooth, diffusion-tight surface offers maximum safety.
Features & Benefits
- Extremely chemical-resistant: Resistant to acids, alkalis, oxidising agents and solvents (e.g. HCl, H₂SO₄, NaOH).
- Hygienic & high purity: Smooth inner surfaces, ideal for CIP/SIP processes, FDA & EU 1935/2004 compliant.
- Temperature-resistant & diffusion-tight: operating range from -200°C to +260°C, with PFA coating thickness of 1-3 mm.
- Antistatic available (conductive version): For ATEX/Ex areas: <10⁶Ω surface resistance.
- Durable & media-neutral: No contact between the medium and the stainless steel base body.
Connection types & variants
- Threaded fittings (male/female according to ISO 228 / NPT): sockets , nipples, elbows, T-pieces, reducers.
- TriClamp fittings (DIN 32676 / ISO 2852): For hygienic pipe connections, CIP/SIP compatible.
- Milk pipe thread fittings (DIN 11851): For the food, beverage and cosmetics industries.
- Special solutions & adapters: transitions , hose nozzles, tank connections – can be combined individually.
Typical areas of application for PFA fittings
- Chemical and process industry: acids, alkalis, solvents, aggressive reactants.
- Pharmaceuticals & biotechnology: sterile processes, high-purity media, active ingredient production.
- Food & beverage technology: Hygienic pipes with CIP/SIP cleaning.
- Semiconductor & clean room technology: ultrapure water, etching media, high-purity process lines.
PFA fittings from M+B offer you maximum safety, purity and durability – even in extreme process environments.
