Claw couplings DIN 3489 for compressed air and hose systems

Claw couplings per DIN 3489 are used for quickly connecting compatible hoses and compressed-air lines. The claw principle enables a robust, detachable connection, provided that both coupling halves match each other in terms of design and dimensions.

This category includes models compliant with DIN 3489. When selecting a model, in addition to the applicable standard, you must also consider the connection size, thread or hose type, seal, and the permissible operating conditions for the specific coupling.

✅ Claw couplings according to DIN 3489

✅ Detachable connection for compatible piping systems

✅ Various connection sizes and types available

✅ Align the coupling and its mating part before use

DIN 3489 as the basis for claw couplings

Claw couplings conforming to DIN 3489 are among the most commonly used connecting elements for suitable compressed air and hose systems. The connection is made via two interlocking coupling halves. This allows lines to be connected without time-consuming screw connections and disconnected again as needed.

Use matching coupling halves

Even within standards-based systems, the specific dimensions and connection types must be verified. For a reliable connection, the coupling geometry, mating part, and seal must all be compatible. Components that do not fit should not be forced together or used as substitutes for one another.

Threaded or hose connection

Depending on the model, DIN 3489 claw couplings may have different connection ends. For threaded versions, the correct thread size must be determined. For hose connections, the hose size and mounting type must be matched. A suitable connection prevents unnecessary adapters and facilitates proper installation.

Check the seal regularly

The gasket plays a key role in the function of the connection and is a typical wear part. Before commissioning, check that it is seated correctly and undamaged. If connections come loose repeatedly, it is recommended to regularly inspect the gasket, clamps, and contact surfaces.

Four Points for Making the Right Choice

✅ Align the DIN 3489 design and mating coupling

✅ Determine the connection size and type

✅ Select a seal that matches the specific coupling

✅ Observe the product’s permissible operating conditions

For a secure compressed-air connection

In compressed-air lines, mechanical forces act on the couplings and hoses. Proper installation and the use of compatible components are therefore essential. We assist in selecting suitable DIN 3489 claw couplings based on the existing connections and dimensions.
