Is the TW Coupling DIN 28450 with BSP Female Thread, Stainless Steel, Type VK suitable for use with liquefied gases or vapors?

No — the TW Coupling DIN 28450 with BSP Female Thread, Stainless Steel, Type VK is not suitable for use with liquefied gases or vapors. The product description explicitly excludes liquefied gases and vapors from its intended applications, even though it is suitable for liquids, bulk materials, and gases (non‑liquefied) within its specified pressure range (-0.8 to 16 bar) and temperature range (-20°C to +65°C) depending on sealing material.

Can the TW Coupling DIN 28450 with BSP Female Thread, Stainless Steel, Type VK be used in food or pharmaceutical applications requiring sanitary materials and certifications?

TW Coupling DIN 28450 with BSP Female Thread, Stainless Steel, Type VK may be suitable for some food and pharmaceutical applications but suitability depends on specific sanitary and certification requirements. Positives: it is made of AISI 316 stainless steel (good corrosion resistance and commonly used in hygienic environments), complies with EN ISO 14420-6 (formerly DIN 28450) for dimensional and mechanical compatibility, and uses a PTFE (Teflon) GD thread seal which is chemically inert and widely used in hygienic systems. Limits/considerations: the description does not state explicit food-grade or pharmaceutical certifications (e.g., FDA 21 CFR 177.1550 compliance for PTFE, EU/EC 1935/2004, EC 10/2011, USP Class VI, or specific hygienic surface finish/Ra values). The coupling is not rated for liquefied gases/vapors, and operating temperature limits depend on sealing material. For sanitary applications you must verify: material traceability and certificate of conformity (e.g., EN 10204 3.1), surface finish and cleanability (polish/Ra if required), compatibility/certification of the PTFE seal for food/pharma, and any client or regulatory standards (FDA, USP, EHEDG, 3A, etc.). Recommendation: obtain supplier documentation and relevant certificates (material certificates, seal certifications, surface finish, and hygiene approvals) and confirm compatibility with your specific product, cleaning/SIP/CIP procedures and regulatory regime before use.
