Can the Socket DN 9 quick coupling with male thread, TST 090 series, brass be used with steam at 200Â°C and 25 bar without degrading the Viton seal?

Yes. Socket DN 9 quick coupling with male thread, TST 090 series, brass can be used with steam at 200Â°C and 25 bar without degrading the Viton seal, provided the following conditions are met: the specified operating temperature range is -20Â°C to +200Â°C (Viton) and the working pressure is 25 bar, matching your steam conditions; the product description explicitly lists steam among suitable media; and installation and service avoid exposure to aggressive chemicals or mechanical wear that could shorten seal life. Caveats: Viton (FKM) maintains chemical and thermal resistance up to 200Â°C but long-term exposure to saturated steam at the upper temperature limit can accelerate aging compared with dry heat. Ensure proper sealing surfaces, avoid dry-running or abrasive contaminants, and inspect/replace seals periodically for critical or continuous steam applications. If conservative safety margins or continuous high-temperature steam service are required, consider consulting the manufacturer for validated steam-cycle data or specifying a higher-temperature seal material.

Is Socket DN 9 quick coupling with male thread, TST 090 series, brass compatible with hot oil at 200Â°C and 25 bar without damaging Viton?

Yes. Socket DN 9 quick coupling with male thread, TST 090 series, brass is specified for working pressure up to 25 bar and an operating temperature range up to +200Â°C with Viton seals. The product description explicitly lists suitability for hot oil and gives operating temperature from -20Â°C to +200Â°C (Viton). Under those conditions (200Â°C, 25 bar) the brass body, stainless-steel internals and Viton sealing are within the stated limits and should not be damaged. Ensure the specific application has no additional chemical or thermal cycling factors that could exceed these limits or require a different elastomer.

Can Socket DN 9 quick coupling with male thread, TST 090 series, brass be used for circulating water in cleaning machines at 25 bar?

Yes. Socket DN 9 quick coupling with male thread, TST 090 series, brass can be used for circulating water in cleaning machines at 25 bar. The product specifications list a working pressure of 25 bar and explicitly state suitability for water in cleaning machines. Materials (brass body and valve components, stainless steel spring/balls) and a 9 mm flow diameter support typical industrial water circuits. Operating temperature range (â20Â°C to +200Â°C with Viton seals) covers normal and elevated temperatures encountered in cleaning processes. Ensure compatibility with your specific water chemistry and system fittings (BSP/metric thread, 60Â° cone seal) and confirm whether you need a version with or without valve for your application.
