EC fittings are designed for low pressure hoses (with maximum working pressure up to 30 bar, depending on the diameter), in particular for rubber and soft plastic hoses: non-reinforced (single layer), with textile reinforcement and with outer steel braid. Crimped with light-duty smooth ferrules using crimping machines for low-pressure hoses (see sections MACHINES FOR INDUSTRIAL HOSE ASSEMBLY PRODUCTION,HOSE REELS AND INDUSTRIAL HOSE ACCESSORIES). Made of zinc-plated carbon steel. Ferrules made of zinc-plated steel or stainless steel.

Unlike high pressure hydraulic fittings, EC fittings do not have a lock attaching a ferrule to a fitting. They have a short hose tail with single or multiple serrations. Broadly used for flexible hose assemblies in fuel, air, water systems – especially in automotive applications. A similar type of fittings and ferrules is used for hose assemblies in water and sanitary system (see group: Sanitary hoses and hose assemblies). EC ferrules can be used to crimp many types of fittings, quick release couplings, with a suitable shape of a hose tail.
