DELPHI FITTINGS
Part #: 61SF
Code 61 Split Flange Half
Product Overview
The Delphi Fittings Part 61SF is one-half of a two-piece split flange clamp, manufactured to SAE J518 / ISO 6162-1 specifications for Code 61 (standard pressure series) hydraulic flange connections. These components are used in pairs, along with four bolts, to securely clamp a flanged head fitting or tube end against a flat port face. The primary advantage of the split design is ease of installation and removal, especially in tight spaces or on existing lines where a single-piece captive flange cannot be slid over the end. Made from high-quality carbon steel for strength and zinc-plated for corrosion resistance, the 61SF Split Flange Half is an essential component for creating robust, reliable, and serviceable flange connections in medium to high-pressure hydraulic systems.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| Standard | Conforms to dimensional specifications of SAE J518 / ISO 6162-1 for Code 61 (Standard Duty). |
| Design | One half of a two-piece clamping set. **Two halves are required for one complete flange connection.** |
| Corrosion Protection | Standard Zinc Plating for enhanced durability. |
| Primary Function | To securely clamp a Code 61 flange head (found on straight adapters, elbows, tees, or hose ends) to a mating port surface. |
| Working Pressure | Designed for use in SAE Code 61 systems, which are typically rated for pressures from 3000 to 5000 PSI (210 to 350 bar), depending on the size. |
| Bolt Requirement | Must be used with four appropriate grade and length bolts for the specific application (bolts are not included with individual halves but are included in our kits). |
Commonly Available Sizes (Part #61SF Series)
Delphi Fittings offers the 61SF Code 61 Split Flange Half in a full range of standard sizes. The size is designated by the flange dash size, which corresponds to the nominal size of the Code 61 connection it is intended to clamp.
Examples include:
- 61SF-08: For 1/2" (-08) Code 61 Flange
- 61SF-10: For 5/8" (-10) Code 61 Flange
- 61SF-12: For 3/4" (-12) Code 61 Flange
- 61SF-16: For 1" (-16) Code 61 Flange
- 61SF-20: For 1-1/4" (-20) Code 61 Flange
- 61SF-24: For 1-1/2" (-24) Code 61 Flange
- 61SF-32: For 2" (-32) Code 61 Flange
Note: This part number is for a single flange half. Two halves are required for one complete flange connection. For complete kits including two halves, bolts, lock washers, and an O-ring, please see our Part #61SF-KIT. For unlisted sizes or specific material requirements, please contact our sales team.
Applications
The Part 61SF Code 61 Split Flange Half is essential for:
- Assembling SAE Code 61 flange connections on hydraulic pumps, motors, valves, cylinders, and manifolds.
- Used in conjunction with flange head fittings (straight adapters, elbows, tees) to connect hydraulic hoses or tubes to equipment ports.
- A wide range of industries including mobile equipment (construction, agriculture, forestry), industrial machinery, material handling, and marine applications.
- Situations where ease of assembly, disassembly for maintenance, and serviceability in the field are important.
Installation & Usage Guidelines
- Ensure the flange head of the adapter or hose fitting, its O-ring, and the port surface are all perfectly clean and undamaged.
- Position the flange head squarely against the port face, ensuring the O-ring is properly seated in its groove.
- Place the two 61SF split flange halves around the neck of the flange head, ensuring they are correctly seated against the back of the flange head.
- Align the bolt holes of the flange halves with the tapped holes in the mating port surface.
- Insert four appropriate grade bolts (with lock washers, if specified by the equipment manufacturer) through the flange halves and into the tapped holes.
- Lightly snug all four bolts by hand. Then, tighten them progressively and evenly in a diagonal or cross pattern to the manufacturer's recommended torque specification for the flange size and bolt grade. This is critical to ensure even clamping force on the flange head and uniform compression of the O-ring seal, preventing leaks.
