Assembling hydraulic tubes with DIN 2353 compression fittings involves creating a leak-tight connection for fluid transfer in hydraulic systems. DIN 2353, also known as the metric compression fitting standard, specifies the dimensions and requirements for the design and construction of these fittings.

 

 

1. Hydraulic tube (usually made of steel)

2. DIN 2353 compression fittings (including nuts, cutting rings, and bodies)

3. Tubing cutter or hacksaw

4. Deburring tool

5. Wrenches or spanners

6. Lubricant compatible with hydraulic fluids

 

 

   Ensure that you have the right DIN 2353 compression fittings for your hydraulic system. These fittings come in various sizes and configurations, so choose the appropriate ones for your tubing and application.

 

   Cut the hydraulic tube to the desired length using a tubing cutter or hacksaw. Make sure the cut is clean and square. Use a deburring tool to remove any burrs or sharp edges from the cut end.

 

   Check the DIN 2353 compression fittings for any damage or defects. Ensure that the cutting ring is in good condition without any nicks or deformities.

 

   Apply a thin layer of a lubricant compatible with hydraulic fluids to the threads and the cutting ring. This helps in proper installation and reduces friction during assembly.

 

   a. Slide the nut onto the tube.

   b. Insert the cutting ring over the tube end, ensuring it is positioned correctly.

   c. Insert the tube into the body of the compression fitting.

   d. Hand-tighten the nut onto the body.

 

   Use two wrenches or spanners to tighten the nut and body together. Hold the body steady with one wrench while using the other to tighten the nut. Follow the manufacturers torque specifications to achieve the proper tightness.

 

   After assembly, visually inspect the connection to ensure that the tube is fully inserted, the cutting ring is seated correctly, and there are no visible gaps. 

 

   Perform a pressure test on the hydraulic system to ensure that the connection is leak-tight. Follow industry standards and guidelines for pressure testing procedures.

 

   Once the connection passes the pressure test, secure the assembly in its final location using appropriate clamps or brackets.
