2C4 DIN Hydraulic Adapter for Systems​

Product Overview

The 2C4 DIN Hydraulic Adapter represents a high-performance solution for connecting hydraulic components in systems adhering to German Industrial Standards (DIN), delivering reliable performance in medium to high-pressure applications. As a key component in the DIN 2353 fitting family, this adapter is specifically engineered to bridge different hydraulic elements while maintaining system integrity and pressure containment. Its precision manufacturing ensures consistent performance in applications where pressure stability and leak resistance are critical factors. The 2C4 adapter has become a staple in industrial hydraulic systems worldwide, valued for its interchangeability and compliance with international standards that facilitate global equipment compatibility.

Product Features

Design & Sealing Mechanism

The 2C4 DIN Hydraulic Adapter features a 24° metric cone design that creates a secure metal-to-metal seal when mated with compatible female fittings, eliminating the need for additional sealing elements in most applications. This precision cone geometry ensures uniform contact pressure across the sealing surface, minimizing the risk of leakage even under pressure fluctuations and vibration. The adapter incorporates metric threads (M14 to M42) with precise tolerances to ensure proper engagement with mating components, while its hexagonal body provides secure wrench access during installation and removal.

Material & Corrosion Resistance

Constructed from high-quality 45# carbon steel, the 2C4 DIN Adapter offers an optimal balance of strength, machinability, and cost-effectiveness for medium to high-pressure applications. The adapter's surface undergoes a trivalent chromate treatment that provides exceptional corrosion resistance and extends service life in harsh industrial environments. This treatment has been verified through 96-hour salt spray testing, ensuring the adapter can withstand exposure to moisture, industrial contaminants, and mild chemicals. For extreme environments, an optional AISI 316 stainless steel version is available, providing superior corrosion resistance for specialized applications.

Pressure Rating & Performance

As a medium-duty to heavy-duty DIN 2353 adapter, the 2C4 is rated for a maximum operating pressure of 6,000 PSI (414 bar), making it suitable for a wide range of high-pressure hydraulic applications. It maintains reliable performance across a temperature range of -30°C to 120°C (-22°F to 248°F), ensuring functionality in both cold and moderately high-temperature environments commonly encountered in industrial settings. The adapter's robust construction allows it to handle pressure spikes up to 8,000 PSI (552 bar) for short durations, providing an extra margin of safety in dynamic hydraulic systems.

Applications

Industrial Hydraulic Power Units

The 2C4 DIN Adapter is widely used in hydraulic power units and hydraulic manifold systems in factory automation and industrial processing facilities. Its high-pressure capability makes it suitable for power unit connections to pumps, valves, and accumulators, ensuring reliable fluid transfer in systems powering everything from precision machine tools to heavy industrial presses.

Mobile Hydraulic Systems

In the mobile hydraulics sector, this adapter finds application in heavy-duty construction vehicles, mining equipment, and agricultural machinery. It is commonly used in hydraulic circuits for boom cylinders, hydraulic motors, and control valves that operate under high pressure and constant vibration. The adapter's robust sealing design ensures reliable performance in the harsh operating conditions encountered in construction and mining environments.

Energy & Infrastructure

The 2C4 DIN Hydraulic Adapter plays a critical role in hydraulic systems for power generation equipment, including hydroelectric turbines, gas turbine control systems, and wind energy installations. Its high-pressure capability and reliable performance make it suitable for the critical hydraulic circuits that control valve actuators, cooling systems, and emergency shutdown mechanisms in power generation facilities where downtime must be minimized.

FAQ

How does the 2C4 DIN Adapter differ from the 1CG4 model?

The primary differences lie in their pressure ratings and construction: the 2C4 is a medium-to-heavy-duty adapter rated for up to 6,000 PSI, while the 1CG4 is a light-duty variant rated for 4,000 PSI. The 2C4 features a thicker wall construction at critical stress points and enhanced thread engagement to handle higher pressures. Additionally, the 2C4 incorporates a more robust sealing cone design with tighter tolerances for improved sealing performance in high-pressure applications. These differences make the 2C4 suitable for more demanding applications than the 1CG4.

What is the proper installation procedure for the 2C4 DIN Adapter?

Proper installation begins with ensuring clean threads and mating surfaces free from burrs, debris, or damage. Apply a thin film of hydraulic system-compatible thread lubricant to the male threads (excluding the sealing cone) before assembly. The adapter should be hand-threaded until the sealing cone makes contact with the mating surface, then tightened to the recommended torque using a calibrated torque wrench. Avoid using thread sealants on the sealing cone itself, as they can interfere with the metal-to-metal seal. Final torque should be verified using a torque wrench, not by feel.

Is thread sealant required for the 2C4 DIN Adapter?

Thread sealant is generally not required for the sealing cone portion of the 2C4 Adapter, as it relies on a metal-to-metal cone seal for pressure containment. However, for thread retention in high-vibration applications, a small amount of medium-strength thread locker (such as Loctite 243) can be applied to the first two threads of the male adapter. This helps prevent loosening while allowing for future disassembly if needed. Never apply sealant or thread locker to the 24° sealing cone surface, as this can compromise the seal integrity.

What torque specifications should be used for installation?

Torque requirements vary by thread size, ranging from 25 ft-lbs for M14 x 1.5 threads to 110 ft-lbs for M42 x 2 threads. Always refer to the manufacturer's torque specification chart for your specific adapter size. It's critical to achieve proper torque—insufficient torque may result in leaks, while excessive torque can damage threads or distort the sealing cone. The torque should be applied gradually in three stages (30%, 60%, 100%) to ensure uniform seating of the sealing cone.

How compatible is the 2C4 Adapter with other international standards?

While designed to DIN 2353 specifications, the 2C4 Adapter can be used with components from other standards when appropriate transition fittings are used. It is not directly compatible with SAE J514 or JIS B8363 components due to differences in thread forms and sealing mechanisms. For systems requiring connection between DIN and other standards, we recommend using a specialized transition adapter designed to bridge these different specifications while maintaining pressure integrity and sealing performance.
