Is the Brass Threaded Quick Release Coupling DN2.7 with Valve, Series 20KA rated for continuous use at 35 bar and compatible with both BSP and metric threads?

Yes. The Brass Threaded Quick Release Coupling DN2.7 with Valve, Series 20KA is rated for working pressures up to 35 bar (suitable for continuous use at that pressure within the specified temperature and media limits) and is available with external or internal BSP or metric threads, so it is compatible with both BSP and metric thread standards.

Can the Brass Threaded Quick Release Coupling DN2.7 with Valve, Series 20KA be used safely with nitrogen at cryogenic temperatures or only within the specified -20°C to +100°C range?

Based on the provided description, the Brass Threaded Quick Release Coupling DN2.7 with Valve, Series 20KA is specified for use with nitrogen and other non‑flammable gases and has an operating temperature range of −20°C to +100°C. Cryogenic nitrogen temperatures (far below −20°C, e.g., −196°C for liquid nitrogen) lie well outside that specified range. Materials listed (brass body, AISI 301 springs/rings, AISI 420 balls, NBR seals) are not rated for typical cryogenic service: NBR hardens and loses sealing performance at very low temperatures, and conventional brass and stainless steels can become embrittled or suffer altered mechanical properties when exposed to extreme cryogenic conditions unless specially treated or specified for cryogenic use. Therefore, you should not use the Brass Threaded Quick Release Coupling DN2.7 with Valve, Series 20KA at cryogenic nitrogen temperatures. Its safe use is limited to the specified −20°C to +100°C range unless the manufacturer explicitly provides cryogenic certification, alternative low‑temperature seals (e.g., PTFE, EPDM designed for cryo), and validation for such service. For cryogenic nitrogen, choose couplings and seals specifically rated and tested for those temperatures.

Additional information

Material	B – brass (bronze)

The compact quick-connect plug series 20KA DN 2.7 is engineered for maximum efficiency in demanding applications, offering a double shut-off system with integrated valves in both the socket and the plug to ensure absolute safety and leak-free performance. Available with external or internal BSP or metric threads, it provides versatile installation options and is suitable for water, air, nitrogen, and other non-flammable gases. With a flow rate of 165 l/min at 6 bar and Δp=0.5 bar for air, and 3 l/min at Δp=1 bar with KV=0.18 for water, it guarantees reliable flow control even under challenging conditions. Designed to withstand working pressures up to 35 bar, the connector is built from high-quality brass with AISI 301 stainless steel springs and rings, AISI 420 steel balls, and durable NBR sealing, ensuring long-lasting resistance to wear and demanding environments. Operating within a wide temperature range from -20°C to +100°C, this solution combines compact dimensions with robust performance, making it ideal for industries that require secure, efficient, and flexible connections in limited spaces.
