Crimping ferrules for 2SN hoses 

Ferrules for 2SN double-braid hose with two steel braids. 

In the group below, there are ferrules, also called crimping sleeves, used for crimping onto 2SN hoses (hydraulic hoses with two steel braids compliant with the DIN EN 853 2SN, SAE 100 R2 AT standard). These ferrules are very characteristic as they have two stripes on the outer surface. Ferrules dedicated to double-braid hoses. Construction: Sleeves made of free-cutting steel: die-forged and then machined on a lathe. Ferrules after heat treatment - annealed which gives them very high ductility and prevents them from cracking during crimping. Ferrules are covered with a zinc layer to protect against corrosion.

Selecting a crimping ferrule for a hose 

The ferrule must match the size of the hydraulic hose. Each ferrule must be matched to a specific hose diameter. The DN designation (nominal diameter) is a key parameter when selecting a ferrule. For example, for a hose with a diameter of DN10, a ferrule also marked as DN10 should be used. Improper matching of the ferrule can result in leaks and weakened connections. The ferrule should be intended for a specific type of hose. Ferrules are designed for specific types of hoses, e.g., ferrules for 2SN hoses differ in construction from ferrules for 4SP or 1SN hoses. Choosing a ferrule adapted to a specific hose construction (e.g., steel or textile braid) is very important to ensure maximum durability and tightness.

Ferrules for crimping hydraulic hoses

Ferrules for crimping hydraulic hoses are mounting elements used in the process of crimping hoses in power hydraulics. Their task is to permanently connect the hose with the fitting, which ensures system tightness and resistance to high working pressure. In practice, the ferrule is deformed during the crimping process, thanks to which it clamps onto the hose and interacts with the steel braid of the hose, creating a durable and safe connection.

How ferrules work in the crimping process

The crimping process consists of mechanically clamping the ferrule onto the hose and the fitting using a specialized press, i.e., a crimping machine. Ferrules for 2SN type hoses are adapted for hoses with double steel braid, which means higher pressure resistance and use in demanding installations. In combination with hydraulic hoses and correctly selected fittings, they create a complete hose assembly ready for operation in the system.

Construction and matching of the ferrule to the hose

Ferrules are most often made of steel, which provides appropriate mechanical strength and resistance to deformation during crimping. Each ferrule must be matched to a specific type of hose and diameter, as incorrect selection can lead to leaks or damage to the hose. In hydraulic systems, the compatibility of all elements is extremely important, which is why ferrules work directly with components such as hydraulic connectors and hose fittings.

Application of ferrules for hydraulic hoses

Ferrules for crimping hydraulic hoses are used in many industries, including agriculture, construction, and industry. Wherever hoses operating under high pressure are used, it is necessary to use a durable and reliable connection. Thanks to properly selected ferrules, it is possible to safely transfer the working medium even in difficult operating conditions.
