Part Number: FS6803-SS

SAE ORFS Male x SAE ORB Male Branch Tee (Stainless Steel)

Product Overview

The Delphi Fittings Part FS6803-SS is a high-performance branch tee adapter forged from 316-grade stainless steel. It is designed to create a 90-degree branch in a hydraulic line while adapting between two different O-ring seal technologies. This fitting features two Male SAE O-Ring Boss (ORB) ends on the straight-through run and one Male O-Ring Face Seal (ORFS) end on the branch. It is the ideal solution for adding a leak-proof ORFS hose line between two ORB-ported components in corrosive or high-purity systems.

Key Features & Specifications

Applications

The FS6803-SS branch tee is a versatile solution for complex hydraulic plumbing:

Adding an auxiliary circuit or component with an ORFS hose assembly in-line between two ORB-ported components (e.g., between a pump and a valve block).
Creating a test point with a superior ORFS connection on a line that runs between two ORB ports.
Perfect for building compact, corrosion-resistant hydraulic manifolds in marine, chemical, and food processing applications.
Simplifies circuits by replacing a standard ORB tee and a separate ORB-to-ORFS adapter with a single, reliable fitting.

Installation & Usage Guidelines

Inspect and lubricate the O-rings on all three male ends of the tee.
Thread the male ORB run ends into their respective female ORB ports and tighten to the specified torque.
With the tee installed, connect the female ORFS swivel nut to the male ORFS branch.
Hold the tee body stationary with a wrench while tightening the ORFS connection to its recommended torque value.
