DELPHI FITTINGS
Product Overview
The Delphi Fittings Part W300 is a specialized flange pad adapter (also known as a block flange or monoblock flange adapter) designed to provide a direct connection from a component surface with a SAE Code 61 bolt pattern to a JIC (37° flare) hydraulic line. This one-piece adapter features an integral Code 61 flange head with an O-ring groove on its base, which mounts directly to a flat port face, and a male JIC 37° flare connection extending from the body. Unlike standard flange head adapters that require separate split flange halves for clamping, this pad adapter is typically bolted directly to the component. This design is often used for compact and robust connections on hydraulic pumps, motors, valves, or manifolds. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the W300 adapter conforms to SAE J518 (for the flange pattern) and SAE J514 (for the JIC end) standards.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| End 1 Configuration | Male 37° JIC Flare (conforming to SAE J514 / ISO 8434-2) |
| End 2 Configuration | SAE Code 61 Flange Pad (integral flange head with bolt holes, dimensions conforming to SAE J518 / ISO 6162-1 for Code 61 port pattern) |
| Body Style | Straight Flange Pad / Block Flange Adapter. |
| Sealing Mechanism | JIC End: Achieves a metal-to-metal seal on the 37° flare cone. Flange End: Utilizes an elastomeric O-ring (seated in the groove on the flange pad face) which compresses against the flat surface of the mating Code 61 port. The adapter is secured directly by bolts through its integral flange holes. |
| Primary Function | To provide a direct, bolted Code 61 flange connection to a component port, adapting it to a male JIC 37° flare for connection to a female JIC swivel fitting or flared tube. |
| O-Ring Material (for Flange end) | Typically Buna-N (Nitrile) 90 Durometer as standard. Viton® (FKM) or other materials available upon request. O-ring is supplied with the fitting. |
| Plating & Finish | Cr3+ Trivalent Zinc Clear (ASTM B117 salt spray tested) |
| Reference Standard | SAE J518 / ISO 6162 (4-Bolt Flange Connection Standard) |

Specific Applications & Hydraulic Circuit Routing
Part W300 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 W300.
- 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.
