DIN 2353 Compression Couplings are well proven for :
● Tube to tube connections
● Tube to threaded port connections
● Tube to hose assembly connections
The practicality of self assembly is a major feature in their appeal as an everyday medium and high pressure pipework accessory.
● Do you need to assemble more than a few connections?
● Do you regularly deal with larger bore sizes?
● Do you use mainly stainless steel connectors?
Hardened Pre Assembly Tool
If your answer to any of the above is yes,then you should certainly use a hardened pre assembly tool for hand assemblies. (For stainless ends this is regarded by manufacturers as essential)
Pre Assembly Machine?
You might like to consider investment in a pre assembly machine. This would ensure that joints are made perfectly every time and will reduce installation time and costs significantly.
Tube End Forming Machine?
Alternatively you might consider hiring a tube forming machine to make your assemblies without the cutting ring, contact us for more details.

DIN 2353 Tube Connectors Assembly Advice
Leaks Only Happen If Components Are Used Inappropriately,
Or Are Incorrectly Assembled
● Incorrectly assembled compression joints are by far the largest single cause of leaks and joint failures.
● By following the very basic instructions and exercising simple quality control during assembly, the finished connection will provide reliable long term service.
● Full assembly instructions here*. Carbon Steel | Stainless Steel
Pay particular attention to:
● Cutting the tube square and deburring
● Performing the correct number of turns
● Checking the ring is secure before final assembly
When assembling Stainless Steel compression couplings, again follow the instructions fully, and pay particular attention to:
● Always use anti seize lubricant on the components
● Always complete the full number of turns, torque requirements are high on larger sizes.
Over 20mm tube od it is recommended that a pre assembly tool be used. A common feedback remark is ‘ it was tightened as far as it would go’. This usually indicates undertightening.. The stated number of turns MUST be carried out, or failure is possible.
