1C DIN Adapter for Industrial Hydraulics​

Product Overview

The 1C DIN Adapter represents a precision-engineered solution for hydraulic system connections in industrial applications adhering to German Industrial Standards (DIN). As a key component in the DIN 2353 fitting family, this adapter is specifically designed to provide secure and reliable connections in medium to high-pressure hydraulic circuits where system integrity is critical. Its robust construction and adherence to strict DIN specifications make it an essential component in industrial hydraulic systems worldwide, particularly in European markets and global facilities utilizing German-engineered equipment. The 1C DIN Adapter combines traditional engineering principles with modern materials to deliver consistent performance in the most demanding industrial environments.

Product Features

Precision Sealing Mechanism

The 1C DIN 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 cone surface undergoes a specialized lapping process to achieve optimal surface finish (Ra 1.6), ensuring maximum contact area with mating components. The adapter incorporates metric threads (M12 to M52) with precise class 6g/6H tolerances to ensure proper engagement and sealing performance.

Material & Corrosion Protection

Constructed from high-quality 42CrMo4 alloy steel (equivalent to AISI 4140), the 1C DIN Adapter offers exceptional mechanical properties for industrial hydraulic applications, including a minimum tensile strength of 1000 N/mm² (145,000 PSI) after heat treatment. The adapter's surface undergoes a multistep corrosion protection process including phosphating and trivalent chromate conversion coating, providing excellent resistance to industrial contaminants and moisture. This treatment has been verified through 200-hour salt spray testing per ISO 9227 standards. For extreme corrosive environments, an optional AISI 316 stainless steel version is available, offering superior resistance to chemical exposure and aggressive industrial conditions.

Pressure Performance & Design

Engineered for heavy-duty industrial applications, the 1C DIN Adapter is rated for a maximum operating pressure of 6,300 PSI (434 bar) for sizes up to M36, with larger sizes rated at 4,500 PSI (310 bar). It maintains reliable performance across a temperature range of -40°C to 150°C (-40°F to 302°F), ensuring functionality in both cold storage environments and high-temperature industrial processes. The adapter features a hexagonal body with increased wall thickness at critical stress points, enhancing durability and providing secure wrench engagement during installation. Its internal flow path is optimized for minimal pressure drop and reduced turbulence in high-flow applications.

Applications

Heavy Industrial Machinery

In factory and industrial settings, the 1C DIN Adapter is widely used in hydraulic systems for heavy machinery such as metal presses, rolling mills, and forging equipment. It provides reliable connections in high-pressure circuits that generate the extreme forces needed for metal forming and fabrication processes, where equipment downtime can result in significant production losses.

Process Industry Hydraulics

The 1C DIN Adapter finds extensive application in process industries including chemical manufacturing, pulp and paper production, and industrial automation systems. It connects hydraulic components in systems powering mixers, valves, and material handling equipment, where it must maintain reliable performance despite exposure to industrial chemicals, moisture, and varying temperatures.

Mobile Industrial Equipment

In mobile industrial applications, including port machinery, waste management equipment, and heavy-duty material handlers, the 1C DIN Adapter provides secure hydraulic connections that withstand constant vibration and mechanical stress. Its robust design ensures reliable performance in outdoor environments exposed to weather conditions and temperature extremes.

FAQ

What distinguishes DIN 2353 adapters from other hydraulic fitting standards?

DIN 2353 adapters, including the 1C model, feature a 24° cone sealing surface that creates a metal-to-metal seal, distinguishing them from SAE's O-ring face seal design or BSP's thread-sealing approach. This cone design provides exceptional vibration resistance and allows for visual verification of proper seating during installation. DIN 2353 specifies precise dimensional tolerances and performance requirements that ensure interchangeability between manufacturers, making these adapters particularly prevalent in European industrial equipment and globally sourced machinery built to German engineering standards.

How does the installation process differ from SAE adapters?

Installing the 1C DIN Adapter requires specific procedures due to its cone sealing design: the 24° cone must make complete contact with the mating surface without gaps. Unlike SAE adapters that use torque specifications based on O-ring compression, DIN 2353 adapters require flange alignment verification before final tightening. Recommended torque ranges from 15 ft-lbs for M12 to 180 ft-lbs for M52 sizes. A thin film of anti-seize compound is recommended on threads (avoiding the cone surface) to prevent galling and ensure proper torque transmission to the sealing surface.

What factors affect the pressure rating of the 1C Adapter?

The 1C DIN Adapter's pressure rating is influenced by several factors: size (smaller sizes handle higher pressures), temperature (pressure rating derates by 20% above 100°C / 212°F), and fluid type (some aggressive fluids may require using the stainless steel version at reduced pressure). The adapter's orientation also matters—inline installations can operate at full rating, while elbow configurations should be derated by 10-15% depending on angle. Always consult the technical datasheet for application-specific pressure recommendations.
