Part Number: FS6600-SS

SAE ORFS Swivel Nut Branch Tee (Stainless Steel)

Product Overview

The Delphi Fittings Part FS6600-SS is a specialized branch tee forged from 316-grade stainless steel. It features two male O-Ring Face Seal (ORFS) ends on the straight-through run and a female ORFS swivel nut on the 90-degree branch. This configuration is expertly designed for tapping into a main hydraulic line to add a male-ended component or tube assembly. The swivel nut on the branch provides significant installation flexibility, making it a superior choice for complex plumbing in corrosive or sanitary systems.

Applications

The unique configuration of the FS6600-SS makes it highly useful in specific hydraulic circuits:

Adding a male-ended component such as a pressure sensor, transducer, or test point to a main hydraulic line.
Tapping into a supply line to feed a sub-circuit that begins with a rigid tube assembly with a male ORFS end.
The female swivel branch is ideal for connecting a fixed male component without needing to rotate it, simplifying installation and maintenance.
Essential for building complex, corrosion-resistant manifolds and circuits in the marine, chemical, and food processing industries.

Installation & Usage Guidelines

Connect the two female ORFS swivel fittings of the main line to the male run ends of the tee, tightening to the specified torque.
Ensure the O-ring on the mating male ORFS fitting for the branch is clean, lubricated, and undamaged.
Thread the tee's female swivel branch onto the male fitting and tighten to its recommended torque value.
Use wrenches to hold the tee body and mating fittings stationary during tightening to prevent stress on the assembly.
