Danfoss Waltech Flared Tube Connection Kit - BO-A Series (Tube Diameter and Configure your service type)

The Danfoss Waltech® BO-A series system is a complete set of highly engineered hydraulic mechanical components, specifically designed for ultra-hermetic coupling and sealing in pre-flared steel pipes (formed at 37° using Bredan / M-WF technology).

This advanced modular system eliminates traditional welding methods or standard cutting rings, distributing mechanical stress homogeneously over the pipe cone. The result is a maximum safety connection that absorbs severe vibrations, eliminates the risk of fatigue breakage, and ensures a 100% leak-free oil circuit. The entire assembly features the high-tech surface treatment Guardian Seal, which offers exceptional resistance of more than 1,000 hours of protection against red corrosion in a salt spray chamber.

Technical and Commercial Glossary:

• Official Catalog Name: Flare connecting parts.

• Commercial Counter Name: Heavy-duty metric flared tube adapter kit.

Components of the Complete Kit (Factory Assembled): This product is not sold as a loose part; it is supplied as an integral modular factory-assembled unit ready for mounting:

1. Intermediate Ring (Zwischenring): Equipped with high-resilience Nitrile (NBR) O-rings for absolute elastic sealing.

2. Sleeve or Pressure Ring (Druckring / Sleeve): Responsible for providing precise mechanical support to the 37° flared cone of the tube.

3. Metric Union Nut (Überwurfmutter / Union Nut): Reinforced component for fastening and applying the final tightening torque.

International Standards: Designed, manufactured, and strictly tested under the high-quality standards of international norms ISO 8434-1 / DIN 2353.
