(A) Features of EIGHTNIPPLE Fittings
*What are the advantages of tightening reinforced yarns firmly?
1. The lifetime of hose will be extended, since it is less likely to have a yarn cast-off bursting.
2. Under the conditions of high temperature or/and high pressure, hose is less likely to be swollen.
3. Performances of hose (such as working pressure and working temperature) are maximized.
※A yarn cast-off bursting occurs when the pressure to tighten the reinforced yarns is lower than the pressure to swell the hose due to the inner pressure. As a result, the reinforced yarns are slided from the end of the hose to the center of the hose, and then the end of the hose bursts due to the inner pressure.

(A) Cut the hose in a perpendicular way. Pass two hose clmaps through the hose.

(C) Tighten the two hose clamps by torque. Hose clamp manufacturer specifies the tightening value. Please follow this value. Pressure performance of the hose might vary depending on its manufacturer and part number.
