Crimp Ferrules

Crimp ferrules advantages

Hose ferrules are typically used in applications where a safe, more durable and reliable clamping method is preferred over band clamps or strapping. RN crimp ferrules provides a 360° uninterrupted compression around the hose and results in a “clean” attachment with no protrusions. Furthermore, RN ferrules have smooth, beveled edges and are available in stainless steel or zinc plated carbon steel. You can install them with a hydraulic crimper and can be used on most hose shank couplings on the market.

You can choose them based on the length of the coupling barb and the actual hose outside diameter. Ferrule must fit snug over the cover of the hose prior to crimping.

Furthermore as a general rule, ferrule should be about 1/4″ shorter than the barb – if the ferrule is longer than the barb it will start to compromise the structure if the hose is bent near the coupling. However if the ferrule is too short then the barb will dig into the tube and lead to premature failure.

As with hose and couplings, hose ferrules are subject to maximum pressures, temperatures, and mechanical forces like end-pull. As a rule, the higher the temperature, the lower the maximum pressure rating for crimp ferrules. Normal operating conditions are -40F to 70/F, above that the crimp ferrule integrity will diminish.
