Part Number: FS6600

SAE ORFS Swivel Nut Branch Tee

Product Overview

The Delphi Fittings Part FS6600 is an SAE O-Ring Face Seal (ORFS) Swivel Nut Branch Tee. This robust steel fitting is designed to create a 90-degree branch from a main hydraulic line, featuring a female ORFS swivel nut on the branch connection for ease of installation and alignment. The two ends on the straight-through 'run' portion are typically configured as male ORFS flat face ends with O-ring grooves. This setup allows for a secure, high-integrity ORFS connection on all three ports, making it ideal for high-pressure systems where superior leak prevention is critical. The swivel nut on the branch allows for the connected hose or component to be oriented precisely without imparting torsional stress. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the FS6600 tee conforms to SAE J1453 / ISO 8434-3 standards.

Key Features & Specifications

Material	High-Grade Carbon Steel
Run End 1 Configuration	Typically Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3)
Run End 2 Configuration	Typically Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3)
Branch End Configuration	Female SAE O-Ring Face Seal (ORFS) Swivel Nut (conforming to SAE J1453 / ISO 8434-3)
Body Style	Tee Adapter, typically forged for strength, with hexagonal (hex) features or flats for wrench engagement.
Sealing Mechanism	Run Ends (Male ORFS): Utilize elastomeric O-rings (seated in grooves on the male faces) which compress against the flat faces of mating female ORFS swivel fittings. Branch End (Female ORFS Swivel): Its internal flat face seals against the O-ring on a mating male ORFS fitting. The swivel nut facilitates easy assembly.
Corrosion Protection	Standard Zinc Plating for enhanced durability and resistance to environmental corrosion.
Primary Function	To provide a T-junction with a female ORFS swivel connection on the branch, and typically male ORFS connections on the run, allowing for versatile and secure hydraulic system design with superior sealing.
Working Pressure	Suitable for high-pressure hydraulic systems, often rated up to 6000 PSI or higher depending on the size and specific application.
O-Ring Material (for Male ORFS run ends)	Typically Buna-N (Nitrile) 90 Durometer as standard. Viton® (FKM) or other materials available upon request. O-rings are supplied with the male ORFS ends.

Commonly Available Sizes (Part #FS6600 Series)

Delphi Fittings offers the FS6600 SAE ORFS Swivel Nut Branch Tee in various common ORFS size combinations. Sizes are typically specified as Run x Run x Branch.

Examples include (Male ORFS Run x Male ORFS Run x Female ORFS Swivel Branch):

FS6600-04-04-04: -04 Male ORFS x -04 Male ORFS (Run) x -04 Female ORFS Swivel (Branch)
FS6600-06-06-06: -06 Male ORFS x -06 Male ORFS (Run) x -06 Female ORFS Swivel (Branch)
FS6600-08-08-08: -08 Male ORFS x -08 Male ORFS (Run) x -08 Female ORFS Swivel (Branch)
FS6600-08-08-06: -08 Male ORFS x -08 Male ORFS (Run) x -06 Female ORFS Swivel (Branch) (Reducing Branch)
FS6600-12-12-12: -12 Male ORFS x -12 Male ORFS (Run) x -12 Female ORFS Swivel (Branch)

Note: The male ORFS ends of this tee include appropriate O-rings. The female ORFS swivel branch connects to a male ORFS fitting which will have its own O-ring. Configurations where run ends are also female swivel may exist under different part series. For unlisted size combinations, specific material requirements (e.g., stainless steel options), or other custom needs, please contact our sales team.

Applications

The Part FS6600 SAE ORFS Swivel Nut Branch Tee is ideal for:

Creating a 90-degree branch connection for a hydraulic hose or tube (terminated with a male ORFS fitting) from a main line that connects to female ORFS swivel fittings.
Adding test points, pressure gauges, sensors, or auxiliary hydraulic circuits that require a female ORFS swivel connection into an ORFS system.
Use in demanding hydraulic applications on mobile equipment, industrial machinery, and manufacturing systems where the superior sealing performance of ORFS and the installation ease of a swivel nut are highly beneficial.
Facilitating complex hydraulic plumbing where precise orientation of the branch line is necessary to avoid stress or interference.

Installation & Usage Guidelines

Thoroughly inspect all ORFS flat sealing faces, O-ring grooves (on the male run ends of the tee), the female ORFS swivel components on the branch, and all mating O-rings and flat faces. Ensure all surfaces are meticulously clean, undamaged, and free from contaminants.
Verify that O-rings are correctly sized, made of compatible material (e.g., Buna-N, Viton®), and properly lubricated with system-compatible fluid. Install lubricated O-rings onto the male ORFS run ends of the tee.
Connect the male ORFS run ends of the tee to mating female ORFS swivel fittings. Hand-tighten the swivel nuts, then use wrenches to tighten to the recommended torque, holding the tee body stationary if needed.
Align the tee for the desired branch orientation.
Connect a male ORFS fitting (which will have its own O-ring) to the female ORFS swivel branch of the tee. The swivel nut allows the tee body to be held stationary while this branch nut is tightened independently to the recommended torque.
Always use appropriate backup wrenches on the tee body and mating components during tightening to prevent distortion or over-tightening.
