SAE ORFS Swivel Nut Straight Adapter (Stainless Steel) - Part FS7504-SS

Part Number: FS7504-SS

SAE ORFS Swivel Nut Straight Adapter (Stainless Steel)

Product Overview

The Delphi Fittings Part FS7504-SS is a straight union adapter featuring female O-Ring Face Seal (ORFS) swivel nuts on both ends. It is designed to connect two male ORFS fittings or hose ends of the same size. Constructed from high-grade 316 stainless steel, this adapter provides a highly secure, leak-free connection while offering maximum corrosion resistance. The dual swivel design is engineered to simplify installation in tight spaces and completely eliminate torsional stress on hose assemblies during tightening, making it a superior choice for demanding hydraulic applications.

Key Features & Specifications

Material High-Grade Stainless Steel (Typically 316 SS)
End 1 & 2 Configuration Female O-Ring Face Seal (ORFS) Swivel (per SAE J1453 / ISO 8434-3)
Body Style Straight Union Adapter with Hex Body.
Sealing Mechanism Seals against the O-rings on the two mating male ORFS fittings. The swivel nuts provide mechanical clamping force.
Corrosion Protection Excellent inherent corrosion resistance from stainless steel.
Primary Function To connect two male ORFS fittings or hose ends of the same size in a straight line with the ease of swivel nuts.
Working Pressure Suitable for high-pressure hydraulic systems, with pressure ratings corresponding to the fitting size per SAE J1453.

Applications

The FS7504-SS swivel adapter is invaluable in hydraulic systems where ease of assembly and corrosion resistance are top priorities:

  • Connecting two male-ended ORFS hose assemblies together to extend a hydraulic line.
  • Joining a hose assembly to a fixed male ORFS port on a component, where the swivel action makes it easy to tighten the connection without rotating the hose.
  • Ideal for complex hydraulic circuits in marine, chemical, and food processing industries where routing is tight and disassembly for maintenance is required.
  • Perfect for applications with high vibration where preventing any stress on the hose during installation is critical to long-term reliability.

Installation & Usage Guidelines

  • Ensure the O-rings are properly installed and lubricated on the male ORFS fittings that are being connected. Inspect male fitting faces for damage.
  • Thread both female swivel nuts onto the male fittings until they are finger-tight.
  • Use a wrench to hold the center hex body of the FS7504-SS adapter stationary.
  • Use separate wrenches on the mating male fittings or hose assemblies to prevent them from rotating.
  • Tighten each swivel nut to the torque specified for its size to achieve a proper, leak-free seal.

Why Choose Delphi Fittings Part FS7504-SS?

  • Effortless Installation: The dual swivel nut design completely prevents hose twist and simplifies assembly, especially in confined or hard-to-reach areas.
  • Leak-Proof Reliability: Creates two independent, high-integrity O-Ring Face Seal connections known for their outstanding performance under pressure and vibration.
  • Superior Material Quality: Manufactured from 316 stainless steel for maximum protection against corrosion and chemical attack.
