Is Quick-connection socket DN7.8 with valve, non-pressure disconnected, threaded, series 1600KE compatible with plugs other than hardened steel 25KA?

Quick-connection socket DN7.8 with valve, non-pressure disconnected, threaded, series 1600KE is specified to guarantee safe operation only when used with plugs made of hardened steel (series 25KA). Therefore it is not recommended or certified for use with plugs other than hardened steel 25KA; using other plug materials may compromise safety and void the guarantee.

What is the recommended maintenance interval for Quick-connection socket DN7.8 with valve, non-pressure disconnected, threaded, series 1600KE?

Quick-connection socket DN7.8 with valve, non-pressure disconnected, threaded, series 1600KE Recommended maintenance interval: - Inspect visually and functionally every 3 months or every 1,000 operating hours (whichever comes first). - Perform detailed maintenance (cleaning, lubrication of moving parts, check/replace NBR seals, inspect spring, balls and ring for wear or corrosion, verify thread integrity and seating) every 12 months or every 10,000 operating hours. - Immediately inspect and service after any exposure to abnormal conditions (excessive vibration, contamination, impact, pressure spikes >12 bar, or use with pneumatic tools contrary to recommendations). - Replace seals and worn components as found; replace coupling if hardened-steel plug compatibility is compromised, or if locking sleeve, balls or spring show significant wear or corrosion. Notes: - Intervals should be shortened when operating near temperature limits (-20Â°C or +100Â°C), in abrasive/contaminated environments, or under frequent connect/disconnect cycles. - Always use plugs made of hardened steel (series 25KA) and ensure supply pressure stays within 2â12 bar to maintain safe operation and longevity.

Quick-connection socket DN7.8 with valve, non-pressure disconnected, threaded, series 1600KE

Q: Can Quick-connection socket DN7.8 with valve, non-pressure disconnected, threaded, series 1600KE be used directly with pneumatic tools?

No . Quick-connection socket DN7.8 with valve, non-pressure disconnected, threaded, series 1600KE should NOT be used for direct connection of pneumatic tools. Although it is designed primarily for compressed air and meets ISO 4414 / EN 983, the manufacturer explicitly warns that vibrations and oscillations from direct tool connection will shorten the couplingâs lifespan. Safe operation is only guaranteed when used with hardened-steel plugs (series 25KA). Use a recommended coupling arrangement or suitable intermediate hoses/adapters to isolate tool-induced vibration and protect the coupling.

Additional information

Material	B – brass (bronze)

Disconnectable non-pressurized quick coupling socket with valve, DN7.8, with external BSPT thread or internal BSP thread, series 1600KE. Safely disconnectable quick coupling for air, compliant with ISO 4414 and EN 983, protects the operator from potential hose whipping effects and reduces disconnection noise. Designed primarily for compressed air. Safe operation of the coupling can only be guaranteed when used with plugs made of hardened steel (series 25KA). Do not use for direct connection of pneumatic tools, as vibrations and oscillations will shorten the lifespan of the coupling. Performance: 2020 l/min (Pe = 6 bar, Δp=0.5 bar – air). Working pressure: 2÷12 bar. Material: nickel-plated brass (body), hardened steel (locking sleeve), galvanized steel (socket), brass (valve), stainless steel (spring, balls, and ring). Sealing: NBR. Operating temperature: from -20°C to +100°C.
