Stainless Steel / Mild Steel Compression fittings
Compression fittings are commonly used in both Mild Steel and Stainless-Steel piping systems to create a leak-proof connection. Mild steel compression fittings are typically used in pressure applications where corrosion is not a problem as they are more prone to corrosion compared to stainless steel compression fittings. On the other hand, Stainless steel compression fittings are preferred for their corrosion resistance and durability, making them suitable for high-pressure and corrosive environments.
When properly installed, compression fittings provide a reliable and secure joint by compressing the fitting onto the pipe, ensuring a tight seal without the need for welding or soldering.
The Basic Function And Use For DIN Compression Couplings
DIN 2353 compression couplings are the industry standard for installing medium and high pressure steel pipework systems, in both carbon and stainless steel
They normally come in these versions:
Series LL Extra light 4mm –
Maximum Working Pressure 100 Bar
Series L Light 6mm –
Maximum Working Pressures
6mm 500 Bar –
Series S Heavy 6mm –
Maximum Working pressures
6mm 800 bar –
**These pressure ratings relate to the higher performance rings in general use, compared to the basic DIN standard ratings. Check with your supplier/manufacturer if necessary
Full compliance with DIN 2353 standard for interchangeability
*This must be done to specific guidelines for leakfree operation

Formed Tube Version
Saving Time
Improving Performance
We also offer a variation on this system that eliminates the use of the olive by using a machine to form the end of the tube to the same tapered configuration.
This does provide a very high degree of integrity in terms of guaranteed correct assembly and leak free operation. This system uses exactly the same DIN 2353 components, but without the olive (cutting ring). assembly time is very much quicker as well as offering this higher integrity. The only disadvantage is the need for a machine. Most serious suppliers in the market will have machines available to hire, making them extremely cost effective for projects where larger numbers of pipes are required.
- Machine made joints of this type are especially beneficial when considered for the larger bore sizes and for stainless steel coupling assembly.
- Alternatively it is worth considering a pre assembly machine to guarantee correct coupling to tube assembly, again especially on larger sizes where significant torque can be required to complete a correct assembly.
