SAE ORB Male x NPSM Pipe Female Swivel 45° Elbow - Part 6902

Part Number: 6902

SAE ORB Male x NPSM Pipe Female Swivel 45° Elbow

Product Overview

The Delphi Fittings Part 6902 is a 45° adapter elbow engineered to connect a female SAE O-Ring Boss (ORB) port to a male NPSM (National Pipe Straight Mechanical) threaded fitting, facilitating a precise 45-degree change in flow direction. This fitting features a male SAE ORB end for a high-pressure O-ring seal and a female NPSM pipe thread with an integrated swivel nut on the other end. The swivel nut on the NPSM side allows for simplified installation and alignment, particularly in confined spaces, without twisting the mating component or hose. NPSM threads are straight and rely on a mechanical seal (e.g., gasket or seal on the male fitting's shoulder). This adapter is crafted from durable carbon steel and zinc-plated for corrosion resistance, ensuring dependable performance in various hydraulic and pneumatic systems.

Key Features & Specifications

Material High-Grade Carbon Steel
End 1 Configuration Male SAE O-Ring Boss (ORB) (per SAE J1926-1 / ISO 11926-1)
End 2 Configuration Female NPSM Pipe Swivel Nut (National Pipe Straight Mechanical - ANSI/ASME B1.20.1)
Angle 45 Degrees
Swivel Feature NPSM female end features a swivel nut for ease of installation and alignment.
Sealing Mechanism ORB End: O-ring (supplied with male ORB) seals against the boss in the female ORB port.
NPSM End: Achieves a mechanical seal, typically with a gasket or O-ring on the mating male NPSM fitting, or against a seat. The swivel nut facilitates tightening this connection.
Corrosion Protection Standard Zinc Plating for enhanced durability.
Primary Function To adapt an SAE ORB port to a male NPSM fitting at a 45° angle, with swivel capability on the NPSM end.
Working Pressure Suitable for hydraulic applications. Specific ratings depend on size and the integrity of the NPSM seal.
O-Ring Material (for ORB end) Typically Buna-N (Nitrile) 90 Durometer. Other materials available upon request.

Applications

The Part 6902 adapter elbow is useful for connecting ORB ports to NPSM male-ended components at a 45-degree angle:

  • Connecting components with ORB ports to hoses or pipes terminating in male NPSM fittings, especially where a gradual turn and swivel connection are advantageous.
  • Use in hydraulic systems on industrial machinery, mobile equipment, and other applications requiring adaptation between these thread types with a directional change.
  • Ideal for installations in confined spaces or where pre-assembled lines need to be connected without imparting twist, thanks to the swivel feature.

Installation & Usage Guidelines

  • Ensure all threads and sealing surfaces (ORB O-ring groove and port boss, NPSM threads, and mating male NPSM sealing face/gasket area) are clean, undamaged, and free from contaminants.
  • For the ORB end, confirm its O-ring is correctly sized, lubricated, and seated. Thread the male ORB end into the female ORB port and tighten to the recommended torque.
  • Align the female NPSM swivel nut with the male NPSM fitting. The swivel nut allows rotation for easy threading. Ensure any required gasket for the NPSM connection is correctly positioned. Tighten the swivel nut to achieve a secure, leak-proof mechanical seal.
  • Use appropriate wrenches on the elbow body (if flats are provided), the ORB end, and the NPSM swivel nut during installation.
