What are DIN 2353 S fittings?
DIN 2353 S fittings are connections designed according to the DIN 2353 (ISO 8434-1) standard in the S (heavy) series, used to join pipes in high-pressure hydraulic systems, guaranteeing a secure and leak-proof connection by means of a shear ring.
What does “S series” mean?
The S series is the heavy-duty series, designed to operate under high pressures and demanding conditions. It can withstand high pressures, reaching up to 800 bar in some cases depending on the diameter and configuration.
What types of DIN 2353 S fittings are there?
Within this category you can find:
- Straight joints
- Elbows (45° and 90°)
- Tests and derivations
- Threaded adapters
- Plugs and reducers
This allows for multiple installation configurations to be covered.
In what applications are DIN 2353 S fittings used?
They are mainly used in:
- Industrial hydraulic systems
- Heavy machinery
- Mobile equipment (public works, agriculture)
- High-pressure installations
What is the difference between the L series and the S series?
The main difference is the pressure capacity:
- L Series (lightweight): for medium pressure applications
- S Series (heavy-duty): for high pressures and more demanding conditions
The S series has thicker walls and greater mechanical strength.
What advantages do DIN 2353 S fittings offer?
- High sealing
- High pressure resistance
- Reliable and standardized assembly
- Long service life
How does the cutting ring system work?
The cutting ring deforms when the fitting is tightened, penetrating the tube and creating a hermetic metal seal, without the need for additional gaskets.
Can DIN 2353 S fittings be reused?
The body of the fitting can be reused, but the cutting ring is not always recommended for reuse, especially in critical applications.
