A hydraulic equal union is a fitting designed to connect two sections of tubing or piping of identical diameter, ensuring a secure and leak-proof connection in hydraulic systems. These unions are essential for maintaining system integrity, allowing for easy assembly, disassembly, and maintenance.

Technical Specifications:

Material: Hydraulic equal unions are commonly manufactured from materials such as malleable cast iron, stainless steel (e.g., ASTM A351 CF8M), carbon steel, brass, Monel, Hastelloy, Inconel, and titanium. The choice of material depends on the application’s requirements, including factors like pressure, temperature, and fluid compatibility.
Thread Standards: These fittings typically adhere to thread standards like ISO 7-1 R/Rp (BSP), ensuring compatibility with corresponding threaded components.
Pressure Ratings (PS): The pressure ratings vary based on the series and material:
- LL Series (Low Pressure): Up to 100 bar.
- L Series (Medium Pressure): 100 to 500 bar.
- S Series (High Pressure): 200 to 800 bar.

These ratings ensure suitability for various industrial applications.

Temperature Range (TS): Depending on the material, the operational temperature ranges are:
- Carbon Steel: -40°C to 120°C.
- Stainless Steel: -60°C to 400°C.
- Brass: -60°C to 175°C.

These ranges indicate the environments in which the unions can operate effectively.

Connection Types: Hydraulic equal unions are available in various configurations to suit different system requirements:
- Tube to Tube: Connecting two tubes directly.
- Tube to Male/Female Thread: Connecting a tube to a threaded component.
- Tube to Butt Weld/Socket Weld: For welded connections.
- Tube to JIC 37°/24° Cone: For specific sealing requirements.

These options provide flexibility in system design and assembly.

Sizes: The unions are available in both metric and imperial sizes:
- Metric Sizes: Ranging from 2 mm to 25 mm.
- Imperial Sizes: From 1/16 inch to 1 1/2 inches.

This range accommodates various tubing dimensions used in hydraulic systems.

Sealing Mechanism: Sealing methods include metal-to-metal or the use of gaskets (e.g., flat or conical bearings) to prevent leaks.
Coating and Surface Finish: Depending on the material and application, unions may have different coatings:
- Carbon Steel: Trivalent zinc plating, yellow plating, or black phosphating.
- Stainless Steel: Bright finish, shot-blasted finish, or electroplated finish.

These finishes enhance corrosion resistance and aesthetic appeal.

Compliance Standards: Manufacturers often adhere to standards such as DIN 2353 and ISO 8434-1, ensuring quality and compatibility across different systems.

Applications:

Hydraulic equal unions are widely used in industries such as construction equipment, drilling platforms, hydro power plants, machine tools, railway technology, shipbuilding, wind turbines, mobile hydraulic equipment, mining, stationary hydraulic equipment, industrial hydraulics, injection molding machinery, aluminum die-casting machinery, sintering machinery, steel mills, hydraulic presses, paper processing, building machinery, agricultural forestry, and lifting and material handling equipment.
