Applications

Fittings for Machine Tools, Molding Machines, Plant Equipment
Manufacturing Equipment of Chemicals, Waste Oil, Waste Fluids and Organic Solvents

Functions

RoHS 2 Free

Characteristics

Original Fittings...EIGHTNIPPLE B Fittings are exclusively designed for HAKKO Hose.
Longer Nipple Shape...Nipple parts are longer than the conventional ones, so they can be tightened securely with two hose clamps. By tightening reinforced yarns securely, the lifespan of the hose becomes longer. Please see this video clip for comparing the pressure-resistance between EIGHTNIPPLE and conventional fittings.
RoHS Compliant...E-FTB is compliant with RoHS requirements (Directive: (EU) 2015/863). (RoHS Compliant means that E-FTB does not contain RoHS 10 restricted substances or it does not exceed the upper threshold of RoHS 10 restricted substances.) Certificate is available on request.
Non-Use of UV-328...E-FTB does not contain UV-328. Certificate is available on request.

Technical Information

(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.

How to Assemble EIGHTNIPPLE Fittings

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

(B) Insert the nipple to the hose. Make sure to insert to the end. There should be no gap between hose and fittings.

e-fts08

(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.

Assembly Done !

*For using conditions such as combustibles and combustible gas, please ground the hose clamps.
Without grounding, the hose clamps might become insulators, accumulating and discharging static electricity. This results in causing a fire to combustibles, leading to explosion.
