DIN 2353 Compression Couplings are well proven for :

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.

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.
