Can the Brass MKV Sealing Ring for TW Coupling DIN 28450 be used with steam or liquefied gases?

No. The Brass MKV Sealing Ring for TW Coupling DIN 28450 must not be used with steam or liquefied gases. The product description explicitly excludes liquefied gas and steam from its suitable media. Its specified temperature range (-20°C to +65°C) and seal materials (NBR joint seal and polyurethane thread seal) further indicate it is not rated for steam or cryogenic/liquefied-gas service.

Is the Brass MKV Sealing Ring for TW Coupling DIN 28450 compatible with food-grade or potable liquid applications?

Brass MKV Sealing Ring for TW Coupling DIN 28450 is suitable for handling liquids, but its compatibility with food-grade or potable liquid applications is not guaranteed by the provided description. The sealing materials specified—NBR (type GSD) for the joint and polyurethane (type GD) for the thread—are common in industrial fluid handling but are not inherently certified for food contact or drinking water use. Food-grade and potable applications typically require specific material certifications (e.g., FDA, EU 1935/2004, WRAS, ACS) and resistance to ingredients, cleaning agents, and temperature regimes used in food/beverage systems. If you need Brass MKV Sealing Ring for TW Coupling DIN 28450 for food or potable liquids, verify with the manufacturer or supplier that: - The brass alloy is compliant with potable-water/food-contact standards (lead content, dezincification resistance, etc.). - The NBR and polyurethane seals have appropriate food-grade certifications (FDA, EU, WRAS/ACS or equivalent). - The complete assembly is tested and certified for potable water or food applications. Without those certifications, do not assume suitability for food-grade or drinking-water use.
