Part Number: FS2501-SS

SAE ORFS Male x NPTF Pipe Male 90° Elbow (Stainless Steel)

Product Overview

The Delphi Fittings Part FS2501-SS is a 90° adapter elbow designed to connect a female O-Ring Face Seal (ORFS) swivel fitting to a female NPTF port at a right angle. This robust fitting combines the superior leak-proof nature of the ORFS connection with the common NPTF port standard, all in a durable, corrosion-resistant 316 stainless steel body. It is an ideal solution for creating a directional change while adapting between two different connection types in demanding hydraulic applications.

Key Features & Specifications

Material	High-Grade Stainless Steel (Typically 316 SS)
End 1 Configuration	Male O-Ring Face Seal (ORFS) (per SAE J1453)
End 2 Configuration	Male National Pipe Tapered Fuel (NPTF) (per ANSI B1.20.3)
Body Style	90° Adapter Elbow.
Sealing Mechanism	ORFS End: O-ring on flat face for a leak-proof seal. NPTF End: Tapered thread interference (sealant recommended).
Corrosion Protection	Excellent inherent corrosion resistance from stainless steel.
Primary Function	To connect a female ORFS swivel fitting to a female NPTF port at a 90° angle.
Working Pressure	Suitable for high-pressure hydraulic systems. Note: The NPTF connection is often the pressure-limiting factor.

Applications

The FS2501-SS adapter elbow is perfectly suited for a range of critical applications:

Connecting a hydraulic hose with an ORFS end to a component (pump, motor, cylinder, valve) that has an NPTF port, where a 90-degree turn is needed.
Efficiently routing hydraulic lines around corners while transitioning from an ORFS hose to hard-piping with NPTF threads.
Essential for installations in corrosive environments such as marine, chemical, and food processing, where stainless steel is required and space is limited.
Simplifying plumbing by replacing a straight adapter and a separate elbow, reducing potential leak paths and installation time.

Installation & Usage Guidelines

ORFS End: Ensure the O-ring is installed, lubricated, and free of defects. Align with the female swivel and tighten to the specified torque.
NPTF End: Apply a suitable thread sealant (PTFE tape or paste) to the male NPTF threads. Thread into the female port and tighten to achieve both a seal and the desired orientation. Avoid over-tightening to prevent damage to the port.
Use a wrench on the fitting body to hold it stationary while tightening the ORFS swivel nut to prevent stress on the NPTF connection.
