Is the 45° DN9 Brass Quick Coupling Socket with Hose End, TST 9 Series compatible with steam and hot oil up to 200°C at 15 bar?

Yes. The 45° DN9 Brass Quick Coupling Socket with Hose End, TST 9 Series is compatible with steam and hot oil up to 200°C at 15 bar. The product description specifies a working pressure of up to 15 bar and an operating temperature range of -20°C to +200°C, with Viton sealing and robust brass/stainless steel construction, and explicitly notes suitability for installations using water, hot oil, or steam.

Can the 45° DN9 Brass Quick Coupling Socket with Hose End, TST 9 Series be used for prolonged continuous operation at temperatures up to 200°C without accelerated Viton seal degradation?

Short answer: Yes — the 45° DN9 Brass Quick Coupling Socket with Hose End, TST 9 Series can be used for prolonged continuous operation at temperatures up to 200°C without accelerated Viton seal degradation, provided normal application conditions are met. Why: The product description explicitly states an operational temperature range of -20°C to +200°C and attributes this capability to the use of high-quality Viton sealing. Standard Viton (FKM) is specified for long-term resistance to elevated temperatures and many aggressive media up to about 200°C; the coupling’s brass body and stainless steel internal components further support durability under continuous service. Caveats: Continuous performance at 200°C assumes: - The specific Viton formulation used is rated for sustained exposure at 200°C (many are, but some formulations have lower limits). - The media (steam, hot oil, water, chemicals) do not include substances or concentrations that chemically attack Viton (e.g., strong ketones, certain amine-containing fluids). - Mechanical stresses, pressure cycling up to 15 bar, and installation conditions do not exceed design limits. If your application involves temperatures constantly at 200°C with aggressive chemicals or serious pressure/thermal cycling, verify the exact Viton grade with the manufacturer or request material certification to ensure long-term seal life.
