Part Number: FS2702

SAE ORFS Male Bulkhead 45° Elbow

Product Overview

The Delphi Fittings Part FS2702 is an SAE O-Ring Face Seal (ORFS) Male Bulkhead 45° Elbow. This specialized fitting is engineered to provide a secure, leak-proof 45-degree connection for hydraulic lines that need to pass through a panel, bulkhead, or equipment wall. It features male ORFS flat face ends, each with an O-ring groove, 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 point. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the FS2702 bulkhead elbow conforms to SAE J1453 / ISO 8434-3 standards, making it ideal for high-pressure applications requiring an angled bulkhead connection with the superior sealing performance of ORFS technology.

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	45 Degrees
Body Style	45° Bulkhead Elbow with a threaded body section 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 high-integrity static face seal. Bulkhead Seal: The locknut mechanically secures the fitting to the panel. For environmental sealing at the panel, an appropriate washer or sealant may be considered by the user depending on 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 of corresponding size)
Primary Function	To provide a 45-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 of the panel.
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 both ORFS ends)	Typically Buna-N (Nitrile) 90 Durometer as standard. Viton® (FKM) or other materials available upon request for specific fluid or temperature compatibility. O-rings are supplied with the fitting.

Commonly Available Sizes (Part #FS2702 Series)

Delphi Fittings offers the FS2702 SAE ORFS Male Bulkhead 45° Elbow in a comprehensive range of common ORFS sizes. Both male ORFS ends are typically of the same size.

Examples include (Male ORFS x Male ORFS):

FS2702-04: For 1/4" (-04) ORFS connections (9/16-18 UNF Thread)
FS2702-06: For 3/8" (-06) ORFS connections (11/16-16 UNF Thread)
FS2702-08: For 1/2" (-08) ORFS connections (13/16-16 UNF Thread)
FS2702-10: For 5/8" (-10) ORFS connections (1-14 UNS Thread)
FS2702-12: For 3/4" (-12) ORFS connections (1-3/16-12 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 FS2702 SAE ORFS Male Bulkhead 45° Elbow is essential for:

Routing hydraulic lines at a 45-degree angle through equipment walls, vehicle chassis, control panels, or machinery enclosures while maintaining a high-integrity, leak-proof ORFS connection on both sides of the barrier.
Providing a fixed, robust 45-degree connection point on a panel for hydraulic hoses or tubes that are terminated with female ORFS swivel fittings.
Optimizing line routing in confined spaces or complex assemblies where a 45-degree turn is preferable to a straight or 90-degree bulkhead fitting, helping to reduce stress on lines and improve flow characteristics.
Use in demanding hydraulic systems on mobile equipment, industrial machinery, and agricultural vehicles where ORFS connections are specified for their superior sealing and vibration resistance.
Applications benefiting from the "zero clearance" assembly feature inherent in ORFS fittings, particularly around the bulkhead interface.

Installation & Usage Guidelines

Prepare the panel or bulkhead by drilling or punching an appropriately sized hole for the threaded body of the FS2702 bulkhead elbow.
Ensure the panel surface around the hole is clean and flat to facilitate a secure and stable mount.
Insert the threaded body of the bulkhead elbow through the prepared 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 or flats to prevent the elbow from turning while tightening the locknut.
Verify that the O-rings for both ORFS male ends are correctly sized, properly lubricated with system-compatible fluid, and correctly seated in their grooves without any damage or twisting.
Connect the male ORFS ends of the bulkhead elbow to the mating female ORFS swivel fittings or specially 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 each swivel nut), tighten each ORFS connection to the manufacturer's recommended torque or by using the "Flats From Wrench Resistance" (FFWR) method suitable for the ORFS size.

Why Choose Delphi Fittings Part FS2702?

Superior Leak Prevention at a 45° Angle: The O-Ring Face Seal design on both ends ensures exceptionally reliable, virtually leak-free 45-degree connections, ideal for bulkhead pass-throughs in high-pressure systems.
Secure and Stable Panel Mounting: The threaded body and included locknut provide a robust, fixed point for hydraulic lines traversing a panel, preventing movement and undue stress on the connections.
Optimized Routing Flexibility: The 45-degree angle allows for smoother line routing in certain configurations compared to 90-degree elbows, potentially reducing flow restrictions and accommodating space constraints.
Zero Clearance Assembly Advantage: Facilitates easier installation and maintenance in applications where space around the bulkhead area is limited.
High-Pressure Capability: Engineered to withstand the demanding pressures commonly encountered in modern hydraulic systems.
Durable Carbon Steel Construction: Manufactured from high-grade carbon steel for excellent strength and longevity.
Enhanced Corrosion Resistance: Standard zinc plating provides robust protection against rust and environmental factors.
Full Adherence to Industry Standards: Meets SAE J1453 / ISO 8434-3 specifications, ensuring compatibility and interchangeability with other standard ORFS components.
Quality-Assured Manufacturing: Produced under Delphi Fittings' rigorous ISO 9001:2015 certified quality management system.
