Stainless steel nut-and-cone fittings are hydraulic connection components consisting of a nut and a cone (cutting ring) that allow for a secure and leak-proof connection of pipes without welding. They are designed according to DIN 2353 (ISO 8434-1), a standard widely used in industrial systems.
The bicone acts as a cutting and sealing element. When the nut is tightened, it deforms around the tube, creating a firm mechanical fit and a watertight seal.
Stainless steel provides high corrosion resistance, compatibility with aggressive fluids, and greater durability in demanding environments such as the chemical or food industries.
Insufficient tightening can cause leaks, while overtightening can deform the tube or damage the bicone, compromising the seal.
When the nut is tightened, the bicone deforms over the tube and creates a mechanical grip along with an airtight seal, preventing leaks even under high pressure conditions.
It is not necessary in the pipe-to-fitting connection, as the sealing is done by the bicone. Sealant may only be required in external threaded connections.
They allow for faster, removable installation without the need for special tools or thermal processes, while maintaining a high level of watertightness.
