Type of industry Unit manufacturer (environmental quality measuring instrument production)
Product adopted Flexible Fluorine (ETFE) Resin SUS Spring Wire Hose [E-SJSP]
EIGHT NIPPLE S [E-FTS]
Fluid Solvent, acid, alkali
Key to adoption Chemical resistance, kink resistance, flexibility, low dissolution behavior, gas barrier property

See below for an example in which the super flexible fluororesin spring hose [E-SJSP] and eight nipple [E-FTS], exclusive-use fitting, were adopted by a manufacturer manufacturing an environmental quality measuring instrument for measuring fine particles in the air.
There are many kinds of environmental quality measuring instruments.
Some machines that measure particles in the air use an air suction hose and air pumping hose.
The Teflon tube has conventionally been used, but the hard tube tends to break and is difficult to attach to the fitting. The manufacturer has been searching for other hoses and a fitting
There are various particles in the air. The hose will be used to measure gas concentrations such as solvent mist, acid and alkali. The hose needs high inner surface smoothness, gas barrier properties, low dissolution behavior, flexibility and fitting attachability, as well as chemical resistance.
The super flexible fluororesin spring hose [E-SJSP], which can be used for both suction and pumping, was chosen as the best hose. The hose has flexibility and transparency along with properties of fluororesin because the inner surface is made of tetrafluoro-based fluororesin.
The manufacturer tested the prototype using a sample. The manufacturer was very pleased, saying that, in addition to the improvement in flexibility and fitting attachability, the transparency enables clearly seeing the stains on the inner surface of the hose.
The super flexible fluororesin spring hose [E-SJSP] and eight nipple [E-FTS] will initially be adopted in a newly manufactured machine.
EIGHT NIPPLE S [E-FTS]

 Flexible Fluorine Resin SUS Spring Wire Hose [E-SJSP] is adopted in water paint pumps!

Type of industry Unit manufacturer (paint pump manufacturing)
Product adopted Flexible Fluorine (ETFE) Resin SUS Spring Wire Hose [E-SJSP]
Fluid N-methylpyrrolidone (NMP), dimethylformamide (DMF)
Key to adoption Chemical resistance, negative pressure use

A company that manufactures an automobile paint pump asked us to select a hose that resists chemicals and allows negative pressure.
In recent years, automobile manufacturers have reviewed paint ingredients as one of their environmental measures according to management policy, resulting in changing from solvent paint to water paint.
The solvent paint commonly needs organic solvents such as toluene and xylene to clean up the paint when changing colors and removing paint. Water paint may gelate depending on the ingredients of the paint when cleaned with toluene and xylene.
Therefore, N-methylpyrrolidone is sometimes used to clean up the water paint.
The chemical above is a polar solvent and is a powerful chemical that dissolves nylon, PE, PP and rubber.
We proposed the super flexible fluororesin spring hose [E-SJSP] to the company that had asked us to select a hose.
The super flexible fluororesin spring hose [E-SJSP] is resistant to solvents such as N-methylpyrrolidone [NMP] and dimethylformamide [DMF] because its inner layer is made of tetrafluoro-based fluororesin ETFE.
The super flexible fluororesin spring hose [E-SJSP] has a stacked-layer structure, providing high transparency, and contains SUS steel wires, offering high flexibility. Thus the hose is a delivery/suction hose that allows negative pressures.
The super flexible fluororesin spring hose [E-SJSP] was found usable and adopted because no defects or deterioration were seen when the company evaluated the chemical resistance and hose performance.
The company was pleased, saying that the cost is slightly higher than conventional hose but the total cost will be reduced considering handling complaints because one pump needs one meter of the hose.

The super flexible fluororesin spring hose is adopted in wall and floor material manufacturing plants!

Type of industry Household equipment and material manufacturing (wall paper, floor material)
Product adopted Flexible Fluorine (ETFE) Resin SUS Spring Wire Hose [E-SJSP]
Fluid Tetrahydrofuran (THF)
Key to adoption Chemical resistance, flexibility, fitting attachability

A company that manufactures wallpaper, cushioned flooring, etc., has used resin hoses for pipes to supply ink in the process in which sheets such as wall paper, etc. are printed.
PVC hoses are used in a production line through which tetrahydrofuran (THF) solvent flows to be added to the ink. The hoses dissolved in one day and had to be replaced daily.
Hakko proposed the super flexible fluororesin spring hose [E-SJSP] that is resistant to tetrahydrofuran (THF) to the company that was trying to handle the hoses dissolving and chemicals leaking through the fittings.
THF is used as a solvent and adhesive that dissolves organic compounds and hoses made of polyvinylchloride and rubber, and makes them soft.
We explained that the super flexible fluororesin spring hose [E-SJSP] made of tetrafluororein is highly resistant to chemicals and can be used without dissolving the hoses.
The super flexible fluororesin spring hose [E-SJSP] was adopted because of high flexibility and transparency, unlike a hard Teflon tube, in addition to high chemical resistance. The hose enables easily taking measures against leakage and attaching the fittings is easily performed in combination with the eight lock [E-FTS], exclusive-use fitting.
The company was pleased, saying that PVC hoses were replaced daily, while super flexible fluororesin spring hose [E-SJSP] can still be used without leakage six months after replacing the PVC hose.

Product adoption
Flexible Fluorine Hose Series
Excellent Chemical Resistance and Flexibility
Flexible Fluorine (ETFE) Resin SUS Spring Wire Hose
[E-SJSP]
Excellent transparency and flexibility similar to that of Polyurethane tubes.
These 4-Fluorine line Fluorine resin hoses provide excellent chemical resistance to almost all chemicals.
Non-vinyl choride material! A rust-resistant stainless steel is used for the spring wire!
E-SJSP has excellent resistance to solvents and most of the chemical substances, because the inner layer is made of ethylene-tetrafuoroethylene (ETFE).
This hose is less likely to be crushed and superior in maintaing the original shape, also allows suction capability.
