SAE ORFS Male x NPTF Pipe Male Adapter - Part FS2404

Part Number: FS2404

SAE ORFS Male x NPTF Pipe Male Adapter

Product Overview

The Delphi Fittings Part FS2404 is a straight adapter designed to provide a reliable connection between a female SAE O-Ring Face Seal (ORFS) swivel fitting or prepared tube end and a female NPTF (National Pipe Taper Fuel / Dryseal) port. This adapter features a male ORFS end with its distinctive flat face and O-ring groove on one side, and a male NPTF pipe thread on the other. The ORFS connection offers superior leak protection due to its O-ring seal, while the NPTF end provides a robust tapered thread seal. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the FS2404 adapter is ideal for high-pressure hydraulic applications requiring a transition between these two common fitting standards.

Key Features & Specifications

Material High-Grade Carbon Steel
End 1 Configuration Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3)
End 2 Configuration Male NPTF Pipe (Dryseal) (conforming to ANSI B1.20.3 / SAE J476)
Body Style Straight Adapter with hexagonal (hex) features for secure wrench engagement.
Sealing Mechanism ORFS End: Utilizes an elastomeric O-ring (seated in the groove on the male ORFS face) which compresses against the flat face of the mating female ORFS swivel fitting, creating a high-integrity static face seal.
NPTF End: Achieves a metal-to-metal seal on the tapered Dryseal threads when mated with a female NPTF port. If connecting to a standard NPT female port, the use of a compatible thread sealant on the male NPTF threads is recommended.
Corrosion Protection Standard Zinc Plating for enhanced durability and resistance to environmental corrosion.
Primary Function To provide a straight, leak-proof connection from a female ORFS swivel fitting or prepared tube end to a female NPTF port.
Working Pressure Suitable for high-pressure hydraulic systems. Specific pressure ratings are dependent on the size of the adapter and the application conditions.
O-Ring Material (for ORFS end) Typically Buna-N (Nitrile) 90 Durometer as standard. Viton® (FKM) or other materials available upon request for specific fluid or temperature compatibility. O-ring is supplied with the fitting.

Applications

The Part FS2404 SAE ORFS Male x NPTF Pipe Male Adapter is ideal for:

  • Connecting hydraulic lines or components with female ORFS swivel ends to equipment or manifolds that have female NPTF ports.
  • Integrating ORFS technology, known for its superior leak resistance, into systems that also utilize traditional NPTF threaded connections.
  • Use in demanding hydraulic applications found in mobile equipment (construction, agriculture), industrial machinery, and manufacturing systems where a secure, high-pressure connection is required between these two fitting types.
  • Facilitating system upgrades or repairs where components with different port standards need to be interconnected.

Installation & Usage Guidelines

  • Thoroughly inspect the ORFS male flat face and O-ring groove, the NPTF male threads, and all mating surfaces (female ORFS flat face and female NPTF port) to ensure they are clean, undamaged, and free from any contaminants.
  • Verify that the O-ring for the ORFS end is the correct size and material (e.g., Buna-N, Viton®) for the application's fluid, temperature, and pressure. Ensure the O-ring is correctly lubricated with a system-compatible fluid.
  • Carefully install the lubricated O-ring into the groove on the ORFS male face of the adapter.
  • For the NPTF male end, apply a suitable thread sealant (such as PTFE tape or a compatible pipe dope) to the threads. This is especially important if mating with a standard NPT female port. Ensure sealant is applied correctly, avoiding the first one or two threads to prevent system contamination.
  • Thread the NPTF male end of the adapter into the mating female NPTF or NPT port. Tighten with a wrench to the appropriate specification to achieve a secure, leak-proof seal on the tapered threads.
  • Align the male ORFS end of the adapter with the mating female ORFS swivel fitting or prepared tube end. Hand-tighten the ORFS swivel nut until the flat faces make contact and the O-ring is engaged.
  • Use appropriate wrenches to tighten the ORFS connection. While holding the adapter body stationary with a backup wrench, tighten the female ORFS swivel nut to the manufacturer's recommended torque value or by using the "Flats From Wrench Resistance" (FFWR) method if specified.

Why Choose Delphi Fittings Part FS2404?
