(16 produtos)
Acoplamentos de garras DIN 3489 para linhas de ar comprimido e sistemas de mangueiras

Acoplamentos de garras DIN 3489 destinam-se à ligação rápida de mangueiras adequadas e linhas de ar comprimido. O princípio de garras permite uma ligação robusta e amovível, desde que ambas as metades do acoplamento sejam compatíveis entre si quanto ao modelo e às dimensões.

A categoria inclui versões de acordo com a norma DIN 3489. Na seleção, para além da correspondência com a norma, devem ser consideradas a dimensão da ligação, a versão com rosca ou para mangueira, a vedação e as condições de funcionamento admissíveis do acoplamento específico.

✅ Acoplamentos de garras segundo a DIN 3489

✅ Ligação amovível para sistemas de linhas adequados

✅ Possibilidade de várias dimensões e tipos de ligação

✅ Verificar o acoplamento e a peça correspondente antes da utilização

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.
