Is the Free-flowing plug DN22, with BSP GZ, hardened steel, 2100 series suitable for compressed air up to 20 bar and flow 12000 l/min at Pe=6 bar?

Yes. Free-flowing plug DN22, with BSP GZ, hardened steel, 2100 series is suitable for compressed air up to 20 bar and a flow of 12â¯000 l/min at Pe = 6 bar. The product specification explicitly states a working pressure of 20 bar and a performance of 12â¯000 l/min at inlet pressure Pe = 6 bar with Îp = 0.5 bar, and it is primarily intended for compressed air. Material (hardened, galvanized steel) and BSP external thread make it appropriate for standard compressed-air installations. Ensure correct installation, compatibility with mating coupling, and adherence to safety and maintenance practices.

Can Free-flowing plug DN22, with BSP GZ, hardened steel, 2100 series be used continuously at 20 bar working pressure for compressed air?

Yes. Free-flowing plug DN22, with BSP GZ, hardened steel, 2100 series is specified with a working pressure of 20 bar and is primarily intended for compressed air. Based on the provided description (material: hardened, galvanized steel; performance: 12,000 l/min at Pe=6 bar, Îp=0.5 bar), it can be used continuously at 20 bar working pressure for compressed air, provided installation and operating conditions follow manufacturer recommendations (proper thread sealing, temperature limits, and routine inspection). If continuous service involves vibration, extreme temperatures, or aggressive contaminants, verify with the manufacturer for suitability and maintenance intervals.

Does Free-flowing plug DN22, with BSP GZ, hardened steel, 2100 series require specific sealing for 20 bar compressed air?

Free-flowing plug DN22, with BSP GZ, hardened steel, 2100 series does require a sealing solution appropriate for 20 bar compressed air. Although the coupling is described as hardened, galvanized steel and rated for a working pressure of 20 bar, the external BSP thread (G thread) alone does not provide a reliable pressure-tight joint without a thread sealant or a suitable gasket. For compressed air at up to 20 bar you should use one of the following, chosen to match assembly practice and maintenance needs: - PTFE tape (thread seal tape) applied correctly to the BSP male thread provides a common, effective seal for metal threads at high-pressure air service. Use several wraps and ensure tape does not enter the flow. - Liquid thread sealant (anaerobic) for a more permanent, vibration-resistant seal; select a product rated for compressed air and the temperature range. - Hemp and paste is a traditional option but less common in industrial compressed-air fittings today. - If the connection design allows, use an Oâring or flat gasket in a face-sealing configuration (if the mating part provides a flange or shoulder). this gives positive sealing without relying solely on thread deformation. Also ensure thread quality (BSP G tolerance), clean threads, correct torque, and compatibility of sealant with galvanized steel and compressed-air media (dry air, lubricated air, condensate). Regular inspection and leak testing after installation are recommended at 20 bar.
