TW couplings
For maximum chemical resistance and safety. Ideal for aggressive media, clean room applications, and food and pharmaceutical technology. In particularly demanding applications such as in the chemical industry, pharmaceutical or food technology, couplings and fittings must be media-resistant, hygienic and diffusion-tight.
TW couplings with PFA coating from M+B Fluid combine the mechanical strength of stainless steel with the chemical resistance of fluoropolymers. Ideal for critical media, high temperatures or ultra-pure processes. They offer even greater resistance than many standard plastic couplings.
The range includes Camlock couplings, clamp connections (ri-Clamp), TW couplings (tankers) and matching stainless steel fittings. All feature a professional PFA (perfluoroalkoxy) internal coating.
In addition to these high-performance products, we also stock plastic couplings made of PP and PVDF for less critical applications.
Technical characteristics
- Temperature range: from -220 °C to +260 °C}
- PFA coating thickness: 1 mm–3 mm, evenly applied
- Highly pure & diffusion-tight even with long stand times
- Chemically resistant to: e.g. ferric chloride, sulphuric acid, caustic soda, solvents
- Conductive versions available: <10^6 Ω surface resistance
- Approved for food and pharmaceuticals in accordance with EU 1935/2004, FDA & USP VI (depending on model)
- Stainless steel carrier: usually 1.4404 or 1.4571 V4/ SS316Ti
Areas of application
- Chemical industry – for aggressive acids, alkalis, solvents
- Pharmaceutical industry – sterile and high-purity liquids
- Food technology – CIP/SIP-compatible, hygienic & tasteless
- Semiconductor industry/ultrapure water technology
- Environmental technology & disposal – for toxic or corrosive media
If your application does not require a metal coupling, our plastic couplings made of PP are a cost-effective and corrosion-free alternative.
