Can the DN7.4 Eurostandard Quick-Connect Socket with Valve, Threaded Nickel-Plated Brass, 26KE Series be used with non-Rectus plugs or only with Rectus type 25KA?

DN7.4 Eurostandard Quick-Connect Socket with Valve, Threaded Nickel-Plated Brass, 26KE Series: The coupling is recommended to be used exclusively with hardened steel Rectus plugs type 25KA for optimal compatibility and durability. While mechanical fit with non-Rectus plugs is not explicitly ruled out in the description, safe, pressure-free disconnection and guaranteed performance in accordance with ISO 4414 and EN 983 are ensured only when used with the specified Rectus 25KA plugs. To maintain rated flow, pressure performance and operator safety, use Rectus type 25KA.

Is the DN7.4 Eurostandard Quick-Connect Socket with Valve, Threaded Nickel-Plated Brass, 26KE Series suitable for use with pneumatic tools if connected through an adapter?

DN7.4 Eurostandard Quick-Connect Socket with Valve, Threaded Nickel-Plated Brass, 26KE Series Format is not intended for direct connection to pneumatic tools. It is engineered for use in compressed air systems with either external or internal BSP threads and provides safe, pressure-free disconnection per ISO 4414 and EN 983. While its flow capacity (1300 l/min at 6 bar), working pressure (up to 12 bar), materials (nickel-plated brass, brass valve, AISI 301/420 springs/locking elements) and NBR seals make it robust and suitable for demanding air applications, the manufacturer explicitly recommends exclusive use with hardened steel Rectus plugs type 25KA for optimal compatibility and durability. Connecting pneumatic tools through an adapter could be possible only if the adapter and the tool connection replicate the intended plug type and meet the same safety, pressure, sealing and material requirements; otherwise it would be contrary to the product guidance and could compromise safety and performance.
