Is the Quick Connector DN4.8 with Valve, Threaded, Chrome-Nickel Brass, Series 1100N suitable for steam applications up to 10 bar and what sealing options support high temperatures?

Yes — the Quick Connector DN4.8 with Valve, Threaded, Chrome-Nickel Brass, Series 1100N is suitable for steam applications up to 10 bar (the coupling’s working pressure is rated to 20 bar, with a specific steam limit of 10 bar). For high-temperature sealing, choose Viton (fluoroelastomer), which supports temperatures up to +200°C. EPDM is rated to +150°C and NBR to +100°C, so for steam near the upper limit Viton is the recommended sealing option.

Can Quick Connector DN4.8 with Valve, Threaded, Chrome-Nickel Brass, Series 1100N be used for hot oils and fuels at elevated temperatures and which seals are recommended?

Quick Connector DN4.8 with Valve, Threaded, Chrome-Nickel Brass, Series 1100N can be used with hot oils and fuels at elevated temperatures only if the sealing material selected is compatible with both the fluid and the operating temperature. Recommended seal choices based on temperature ranges in the product description: - NBR (Nitrile): usable from -20°C to +100°C — suitable for many oils and fuels at moderate temperatures but not for high-temperature service. - Viton (FKM): usable from -25°C to +200°C — the best general recommendation for hot oils and most fuels at elevated temperatures due to superior heat and chemical resistance. - EPDM: usable from -50°C to +150°C — good for higher temperatures but generally not recommended for most hydrocarbons (fuels/oils) because EPDM has poor resistance to petroleum-based fluids. Also consider fluid-specific compatibility (some fuels or additives may attack certain elastomers), maximum working pressure (up to 20 bar; 10 bar for steam), and system safety requirements. For hot oils/fuels at elevated temperatures, Viton seals are typically recommended; verify against the specific fluid’s chemical compatibility data and operating temperature before final selection.
