DELPHI FITTINGS
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. |
| 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. |
| 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. |
| Plating & Finish | Cr3+ Trivalent Zinc Clear (ASTM B117 salt spray tested) |
| Reference Standard | SAE J1453 / ISO 8434-3 (O-Ring Face Seal Standard) |

Specific Applications & Hydraulic Circuit Routing
Part FS2702 fittings provide reliable fluid power conveyance in demanding mobile and stationary equipment circuits:
- High-Vibration Mobile Equipment: Excavator booms, mining equipment, and hydrostatic drives where Part FS2702 prevents hydraulic weeping under intense shock loads.
- Zero-Clearance Manifold Assembly: Flat face design allows slip-in component replacement without springing or spreading rigid hydraulic tubes.
- Extreme Pressure Impulse Circuits: Elastomeric face seal remains 100% leak-free throughout repetitive thermal cycles and impulse spikes.
Installation & Assembly Guidance
- O-Ring Retention Inspection: Inspect the machined face groove to ensure the O-ring is properly seated and retained prior to mating.
- Face-to-Face Alignment: Bring the flat faces into parallel contact before hand-threading the swivel nut to avoid pinching the O-ring.
- Calibrated Torque Tightening: Tighten the nut to the specified SAE J1453 torque value using a calibrated torque wrench.
- Dual-Wrench Counter-Torque: Always hold the fitting body hex with a backup wrench while torquing the connection to prevent twisting.
