DELPHI FITTINGS
Product Overview
The Delphi Fittings Part 62SF is one-half of a two-piece split flange clamp, manufactured to SAE J518 / ISO 6162-2 specifications for Code 62 (heavy-duty, high-pressure series) hydraulic flange connections. These components are used in pairs, along with four high-strength bolts, to securely clamp a Code 62 flanged head fitting or tube end against a flat port face. The split design is essential for ease of installation and removal, particularly in confined spaces or on existing lines where a single-piece captive flange cannot be used. Made from high-quality carbon steel for maximum strength and zinc-plated for corrosion resistance, the 62SF Split Flange Half is a critical component for creating robust and reliable flange connections in the most demanding high-pressure hydraulic systems.
Key Features & Specifications
| Material | High-Grade Carbon Steel (often forged for high strength) |
|---|---|
| Standard | Conforms to dimensional specifications of SAE J518 / ISO 6162-2 for Code 62 (Heavy Duty). |
| Design | One half of a two-piece clamping set. **Two halves are required for one complete flange connection.** Thicker and more robust than Code 61 halves. |
| Bolt Requirement | Must be used with four appropriate high-strength bolts (typically SAE Grade 8 or metric Class 10.9 or higher) and lock washers for the specific application (bolts are not included with individual halves but are included in our kits). |
| Plating & Finish | Cr3+ Trivalent Zinc Clear (ASTM B117 salt spray tested) |
| Reference Standard | SAE J518 / ISO 6162 (4-Bolt Flange Connection Standard) |
| Sealing Mechanism | Face O-Ring Compressed via 4-Bolt Clamping Halves into Port Spotface |

Specific Applications & Hydraulic Circuit Routing
Part 62SF fittings provide reliable fluid power conveyance in demanding mobile and stationary equipment circuits:
- High-Flow Pump & Motor Outlets: Large-bore fluid conveyance on main pump manifolds, hydraulic motors, and industrial power units utilizing Part 62SF.
- Severe Shock & Pressure Pulsation: Distributes mechanical clamping force across four high-tensile bolts to eliminate fitting fatigue and leakage.
- Heavy Equipment Hydraulic Mainlines: Heavy construction, marine winches, and industrial presses requiring robust 4-bolt flange interfaces.
Installation & Assembly Guidance
- Flange Face & O-Ring Seating: Verify the captive O-ring is lightly lubricated and seated cleanly in the flange head groove.
- Cross-Pattern Bolt Tightening: Snug all four Grade 8 / 10.9 bolts finger-tight, then tighten progressively in a diagonal crossover pattern.
- Torque Specification Adherence: Torque bolts evenly to SAE J518 specifications to ensure parallel clamping without cocking the flange halves.
- Inspection & Retorque: Check split flange gap clearance to ensure equal spacing between clamp halves and port face.
