Can Quick Coupling for Liquids DN4, BSP Female Thread, Nickel-Plated Brass, CEJN NON-DRIP tolerate 20 bar and which seal options (NBR, Viton, EPDM) suit my fluid and temperature range?

Quick Coupling for Liquids DN4, BSP Female Thread, Nickel-Plated Brass, CEJN NON-DRIP Format: Yes — these leak-free flat-face quick couplings are rated for working pressures up to 20 bar. Seal options and suitability: - NBR (Buna‑N): Suitable for water, mineral oils and many hydraulic fluids; temperature range roughly -15°C to +100°C. Good general-purpose choice if fluid is petroleum-based and temperatures remain moderate. - Viton (FKM): Best for aggressive oils, fuels, many chemicals and higher temperatures; temperature range up to about +205°C. Choose Viton for hot fluids or where chemical compatibility with hydrocarbons, solvents or some acids/bases is required. - EPDM: Excellent for water, steam, glycols, and many polar chemicals; temperature range typically up to about +150°C (but often specified from -15°C). Do not use EPDM with mineral oils, fuels or many solvents. Recommendation: Match seal material to your fluid chemistry and operating temperature—NBR for general oil/water at moderate temps, Viton for hot or chemically aggressive fluids (including many oils/solvents), EPDM for water/steam/glycol systems but avoid with hydrocarbons. If uncertain, provide your exact fluid and temperature extremes for a specific compatibility check.

Can the Quick Coupling for Liquids DN4, BSP Female Thread, Nickel-Plated Brass, CEJN NON-DRIP be color- or key-coded to prevent misconnection in multi-line systems?

Yes. The Quick Coupling for Liquids DN4, BSP Female Thread, Nickel-Plated Brass, CEJN NON-DRIP can be supplied with optional color coding or key coding to prevent misconnection in multi-line systems. Color coding makes visual identification easy, while key coding (unique keyways or pin patterns) physically prevents incompatible couplings from mating. These options increase safety and reliability by reducing human error and cross-contamination risk in complex installations.
