Part Number: FS2701

SAE ORFS Male Bulkhead 90° Elbow

Product Overview

The Delphi Fittings Part FS2701 is an SAE O-Ring Face Seal (ORFS) Male Bulkhead 90° Elbow. This robust fitting is engineered to provide a secure, leak-proof 90-degree connection for hydraulic lines that need to pass through a panel, bulkhead, or equipment wall. It features male ORFS flat face ends with O-ring grooves on both sides of the elbow, allowing connection to female ORFS swivel fittings or specially prepared tube ends. A locknut is included to firmly secure the elbow to the panel, ensuring a stable and durable pass-through. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the FS2701 bulkhead elbow conforms to SAE J1453 / ISO 8434-3 standards, making it ideal for high-pressure applications where reliability and zero-clearance assembly are critical in angled configurations.

Key Features & Specifications

Material	High-Grade Carbon Steel
End 1 Configuration	Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3)
End 2 Configuration	Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3)
Angle	90 Degrees
Body Style	90° Bulkhead Elbow with a threaded body for panel mounting and a separate locknut. Hexagonal features for wrenching.
Sealing Mechanism	Both ORFS ends utilize an elastomeric O-ring (seated in the groove on each male ORFS face) which compresses against the flat face of the mating female ORFS swivel fitting or prepared tube end, creating a superior static face seal. Bulkhead Seal: The locknut secures the fitting to the panel. An additional washer or sealant might be used by the installer for environmental sealing if required by the application.
Corrosion Protection	Standard Zinc Plating for enhanced durability and resistance to environmental corrosion.
Included Component	Locknut (e.g., Part FS306 ORFS Bulkhead Locknut)
Primary Function	To provide a 90-degree, through-panel connection for ORFS hydraulic lines, securely mounted with a locknut, and connecting to female ORFS swivel fittings or prepared tubes on both sides.
Working Pressure	Suitable for high-pressure hydraulic systems, often rated up to 6000 PSI or higher depending on size.
O-Ring Material (for both ORFS ends)	Typically Buna-N (Nitrile) 90 Durometer as standard. Viton® (FKM) or other materials available upon request. O-rings are supplied with the fitting.

FS2701-10: For 5/8" (-10) ORFS connections (1-14 UNS Thread)
FS2701-12: For 3/4" (-12) ORFS connections (1-3/16-12 UN Thread)
FS2701-16: For 1" (-16) ORFS connections (1-7/16-12 UN Thread)

Note: Each bulkhead elbow includes a corresponding locknut (e.g., Part FS306) and O-rings for both ORFS male ends. For unlisted sizes, specific material requirements (e.g., stainless steel options), or other custom needs, please contact our sales team.

Applications

The Part FS2701 SAE ORFS Male Bulkhead 90° Elbow is essential for:

Routing hydraulic lines at a 90-degree angle through equipment walls, vehicle chassis, control panels, or machinery enclosures while maintaining a leak-proof ORFS connection on both sides.
Providing a fixed, robust 90-degree connection point on a panel for hydraulic hoses or tubes terminated with female ORFS swivel fittings.
Optimizing line routing in confined spaces by allowing an immediate directional change at the bulkhead pass-through point, crucial in mobile equipment, industrial machinery, and complex hydraulic systems.
Applications benefiting from the "zero clearance" assembly feature of ORFS fittings, especially around the bulkhead area.

Installation & Usage Guidelines

Prepare the panel or bulkhead by drilling or punching an appropriately sized hole for the threaded body of the FS2701 elbow.
Ensure the panel surface around the hole is clean and flat to facilitate a secure mount.
Insert the threaded body of the bulkhead elbow through the hole from one side.
Slide the provided locknut over the protruding threads on the other side of the panel and tighten it securely against the panel surface. Use a wrench on the fitting's hex body to prevent the elbow from turning while tightening the locknut.
Verify that the O-rings for both ORFS male ends are correctly sized, lubricated, and properly seated in their grooves without damage.
Connect the male ORFS ends of the bulkhead elbow to the mating female ORFS swivel fittings or prepared tube ends on each side of the panel. Hand-tighten the swivel nuts until the flat faces meet the O-rings.
Using appropriate wrenches (one to hold the bulkhead elbow body if necessary, and one for the swivel nut), tighten each ORFS connection to the manufacturer's recommended torque or by using the "Flats From Wrench Resistance" (FFWR) method.

Why Choose Delphi Fittings Part FS2701?

Superior Leak Prevention at an Angle: The O-Ring Face Seal design on both ends ensures exceptionally reliable, virtually leak-free 90-degree connections, even for bulkhead pass-throughs in high-pressure systems.
Secure Panel Mounting: The threaded body and included locknut provide a stable, fixed point for hydraulic lines traversing a panel, preventing movement and stress.
Space-Saving 90° Design: Ideal for optimizing routing in tight installations by combining a right-angle turn with a bulkhead mounting function.
Zero Clearance Assembly Advantage: Facilitates easier installation and maintenance in applications where space around the bulkhead is limited.
High-Pressure Capability: Engineered to withstand the demanding pressures common in modern hydraulic systems.
Durable Carbon Steel Construction: Manufactured from high-grade carbon steel for excellent strength and longevity.
