Steel safety coupling Series 4000 with hose connection for PVC hoses

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
