4SH INTERLOCK crimp ferrules

What are 4SH Interlock double-lock ferrules? 4SH Interlock crimp ferrules with a double lock (T41) are designed for 4SH interlock fittings. The double lock ensures the highest safety at very high pressures. 4SH Interlock double-lock ferrules T41 are specialized components used in the process of crimping high-pressure hydraulic hoses, designed for 4SH class hoses. The double-lock design, known as Interlock, provides exceptional joint strength, which is crucial in the most demanding hydraulic power applications. Ferrules with Interlock technology stand out with a special design that allows for a durable and secure connection between the fitting and the hose. Thanks to the double lock, the ferrule penetrates deeper into the hose structure, increasing resistance to extreme pressure and dynamic loads. This solution minimizes the risk of leakage, ensuring high tightness and durability of the hydraulic system. Main features of Interlock ferrules: double lock – an additional layer of protection improving the grip of the fitting inside the hose, resistance to high pressure – designed to work under extreme pressure load conditions, solid construction – made of high-grade steel resistant to abrasion and corrosion, increased joint durability – elimination of the risk of loosening or damage during operation.

Application of double-lock Interlock ferrules 

4SH Interlock ferrules are used wherever extreme loads and reliability requirements for hydraulic connections occur. Ferrules are used together with interlock fittings in machines and devices utilizing very high operating pressures - large machines. Example applications include: heavy industry, e.g., construction and mining machinery operating in difficult conditions and requiring secure connections, transport and logistics, where resistance to vibrations and dynamic loads is key to system durability, energy and oil industry, where very high operating pressures occur, agriculture, for machines working in demanding environmental conditions.
