BLX couplings

Effortless, heavy-duty hydraulic connections

No more slow and cumbersome tool changes. The BLX’s one-hand bayonet connection lets you connect and disconnect hydraulic lines quickly and effortlessly — without compromising performance. Based on the proven TLX coupling, BLX is designed and tested to handle high surge flows and pressure impulses, ensuring reliable operation in even the most demanding hydraulic applications. BLX outperforms conventional screw couplings in every way: faster, stronger, and more reliable.

BLX is ideally suited for hydraulic attachments in demanding construction, recycling, demolition, and deconstruction work, including:

• Hydraulic shears
• Hydraulic breakers
• Hydraulic hammers
• Compactors and crushers
• Other specialized hydraulic attachments

CEJN BLX will be available from January 2026.

• One-hand operation

  Connect and disconnect quickly and effortlessly — no tools required.

• Minimized downtime

  Faster to connect means more time in operation and less time lost to tool changes.

• Reduced fuel consumption

  Optimized flow reduces pressure drop and energy loss, saving fuel over time.

• High resilience to surge flows and pressure impulses

  The BLX is designed and tested to withstand the toughest hydraulic conditions.

• Compact design

  High flow capacity in a smaller coupling allows for reduced size and weight, without compromising performance — saving space on your equipment and lowering the overall machine weight.

• Sustainable solution

  The BLX is designed to be long-lasting and with responsibility for the environment: spill-free operation, lead-free, and a wide selection of spare parts for easy maintenance to further enhance the coupling lifespan.

Low pressure drop for higher efficiency and profitability

The BLX offers exceptional flow performance at low pressure drops, delivering high flow in a compact size. This means you can downsize your hydraulic system without sacrificing flow capacity — saving space, reducing weight, and cutting fuel consumption.

Less pressure loss reduces internal resistance in the coupling, resulting in less energy being converted into heat as the oil passes through. Lower heat inside the coupling reduces thermal stress on the body and seals. This reduces wear, extends component life, and ensures consistent performance in demanding applications.

A low pressure drop also enhances safety by reducing the risk of bursts or leaks caused by excessive pressure build-up. BLX delivers more power with less energy, delivering reliable, efficient, and cost-effective hydraulic performance.

BLX bayonet lock vs traditional screw couplings

The BLX features a robust bayonet lock with a foldable lever for quick, one-hand operation, even under residual pressure. It provides secure connection and disconnection and can be extended with a pipe for extra leverage when residual pressure is high. When connected, the lever folds neatly into the coupling, becoming a compact unit.

While screw-to-connect couplings are traditionally valued for rigid connections, the BLX’s bayonet lock design has demonstrated equal performance in extensive impulse testing with heavy side loads.

With its foldable lever and bayonet mechanism, BLX delivers faster handling, high strength, and proven reliability in demanding hydraulic applications.
