Is the Double-Sided Quick-Connect Brass Socket, BSPT Male, Series 25 DN 7.4 compatible with common pneumatic tools and laboratory sampling systems?

Yes. The Double-Sided Quick-Connect Brass Socket, BSPT Male, Series 25 DN 7.4 is compatible with common pneumatic tools and laboratory sampling systems. Its solid brass body, AISI 301 springs and rings, AISI 420 locking balls, and NBR seals ensure durability and leak resistance under intensive use. The ULTRA-FLO valve provides an exceptionally high flow rate (780 l/min at 6 bar, Δp=0.5 bar), making it suitable for pneumatic tool supply and fast, accurate liquid/gas sampling. With a working pressure up to 35 bar and an operating temperature range of -20°C to +100°C, it fits a wide range of industrial and lab environments. The external BSPT male thread enables straightforward integration with standard BSPT fittings commonly used in these systems.

Can the Double-Sided Quick-Connect Brass Socket, BSPT Male, Series 25 DN 7.4 maintain leak-free performance at the maximum flow rate of 780 l/min under continuous industrial use?

Yes. The Double-Sided Quick-Connect Brass Socket, BSPT Male, Series 25 DN 7.4 is designed to maintain leak-free performance at the stated maximum flow rate of 780 l/min (Pe = 6 bar, Δp = 0.5 bar, air) under continuous industrial use. Its solid brass body, precision components (AISI 301 springs and rings, AISI 420 locking balls) and durable NBR seals, together with the ULTRA-FLO valve, provide high tightness and long-lasting sealing even during intensive operation. The coupling’s rated working pressure up to 35 bar and operating temperature range –20°C to +100°C further support reliable, continuous performance across demanding industrial and laboratory environments. Proper installation, compatibility with system parameters, and routine maintenance are required to realize this leak-free performance in practice.
