Steel safety coupling Series 4000 with hose connection for PVC hoses

Safety couplings reduce the risk of injury from compressed-air hoses flying around because the coupling is vented before the connection is released. This procedure offers a greater level of safety, e.g. in the case of overhead installation. The connection can be released with one hand; the other hand remains free to hold the components.

High flow rate of up to 3700 l/min and a maximum operating pressure of 16 bar


Allows optimal compressed air supply and power delivery for compressed air consumers. Result is greater productivity and lower energy costs.



Ergonomically shaped locking sleeve


This ensures a secure grip and prevents the component from slipping off.



Low coupling force permits one-handed operation


Minimal force is required for simple, fast and safe coupling and decoupling.



Airtight connections


Low energy use and high efficiency



Hardened locking sleeves


For max. load-bearing capacity and long service life



Exposed surfaces are chrome-plated, nickel-plated or galvanised


High corrosion resistance – protected even under demanding conditions.



Safety coupling with single-stage decoupling process


  • One-handed decoupling by pulling back the locking sleeve

  • The coupling vents automatically and the sleeve springs back to the starting position


Fittings comply with the European standard and have a nominal width of 10.4 mm


Euro profiles are compatible with other compressed air fittings
