Characteristics

Long Duration...Due to the PVC with oil-proof plasticizer, hose does not become hardened even though oil and hot water are transferred.
Lightweight...E-STB is very lightweight and flexible, compared with rubber hose.
Pressure-Proof...I.D. Size (6mm - 25mm) can stand up to 1.0MPa (10Bar) at 20$^\circ$C working pressure.
Oil Resistance...Compared with a normal PVC braided hose, E-STB shows the property of oil resistance.
Easy to Cut...Since we print the cut mark on the hose every meter, it is easy to cut the length you would like to.
Transparency...E-STB (clear green color) enables you to check the fluid very easily.
Original Fittings...By using our original fittings, you can avoid accidents which are caused by incorrect choices of hose and fittings. For more information on our original fittings, please scroll down to the end.

Certificates and Regulations

RoHS Compliant...E-STB is compliant with RoHS requirements (Directive: (EU) 2015/863). (RoHS Compliant means that E-STB 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. Certificate is available on request.
Non-Use of UV-328...E-STB does not contain UV-328. Certificate is available on request.

Cautions:

Due to the yarn-reinforced hose, please use the joints to seal an inner surface of the hose.
Please do not use the joints to seal an outer surface of the hose. This may result in the bursting or coming off from the hose.
Compared with a normal PVC hose, E-STB is superior in oil-resistance. However, depending on the use time and temperature, hose might harden.
When you use our products, please refer to "Precautions for Use." ("The Precautions for Use" is also available at the product specifications of E-STB, which can be downloadable from here.)
In terms of chemical resistance, please refer to "Chemical Resistance Data."

Technical Information

(A) Relationship between Working Temperature and Maximum Working Pressure

(B) Oil-proof Comparison Data: E-TB vs. E-STB

Test Method: Fill the insulating oil (mineral oil) into the hose and measure the weight change at the room temperature of 60 $^\circ$C.

Test Result: After four weeks, E-STB loses weight by 6%, while E-TB loses weight by 14%.

Insights: Since the plasticizer soaks into the insulating oil, E-TB becomes harder than E-STB.

HAKKO Original Fittings for E-STB

Product Name	Materials, Characteristics
EIGHTLOCK S Fittings [Model Number: E-ELS]]	Material: SUS304 (SS304) (Body, Ring, Nut), POM (Sleeve) Our Nut Type Original Made-in-Japan Fittings Since the inner layer of the fitting is flat and does not use the rubber packing, fluid accumulation is unlikely to occur. Thus, it is easy to wash out. Since you do not need hose clamp and the controlling torque value, you can standardize how to install the fitting.

EIGHTLOCK B Fittings [Model Number: E-ELB]]	Material: BSBM (Body, Ring, Nut), POM (Sleeve) Our Nut Type Original Made-in-Japan Fittings Since the inner layer of the fitting is flat and does not use the rubber packing, fluid accumulation is unlikely to occur. Thus, it is easy to wash out. Since you do not need hose clamp and the controlling torque value, you can standardize how to install the fitting.

EIGHTNIPPLE S Fittings [Model Number: E-FTS]]	Material: SUS316L (SS316L) SUS316L (SS316L) is superior in corrosion resistance, so you can transfer a wide range of fluids. Two-stage flat nipple structure which maximizes hose pressure Our Original Barb Nipple Fittings Made-in-Japan Fittings

EIGHTNIPPLE B Fittings [Model Number: E-FTB]]	Material: BSBM (Brass) Compliant with RoHS2 requirement Two-stage flat nipple structure which maximizes hose pressure Our Original Barb Nipple Fittings Made-in-Japan Fittings

EIGHTLOCK Ferrule Fittings [Model Number: E-ELF]]	Material: Body: SCS16, Nut and Ring: SCS13 (Sleeve: POM) You can replace a hose even though the hose needs replacement, since EIGHTLOCK Ferrule Fitting is a nut ferrule fitting. You can install and detach the fitting on site. You can make use of a wide range of usages such as pipes for chemicals, food, beverage and alcohol. The nipple end is less likely to accumulate fluids, so you do not have to worry about contamination very much.

EIGHTLOCK Ferrule Fittings with PFA Lining [Model Number: E-ELF-PFA]]	Material：Body: SCS16, Wetted Part: PFA Lining, Nut and Ring: SCS13 (Sleeve: POM) Due to PFA Lining, you can transfer fluids that are not possible for metal fittings. You can replace a hose even though the hose needs replacement, since EIGHTLOCK Ferrule Fitting is a nut ferrule fitting. You can install and detach the fitting on site. You can make use of a wide range of usages such as pipes for chemicals, food, beverage and alcohol. The nipple end is less likely to accumulate fluids, so you do not have to worry about contamination very much.

EIGHTLOCK S Fittings (with Hose Guide) [Model Number: E-ELS-GN]]	Material: SUS304 (SS304) (Body, Ring, Nut), POM (Sleeve) Our Nut Type Original Made-in-Japan Fittings with Hose Guide Since the inner layer of the fitting is flat and does not use the rubber packing, fluid accumulation is unlikely to occur. Thus, it is easy to wash out. Since you do not need hose clamp and the controlling torque value, you can standardize how to install the fitting.

Cautions:

For EIGHTNIPPLE S and B Fittings, please fasten with two hose clamps.
We do not have our original fittings for some sizes. For these sizes, please select fittings sold in the market. Please also make sure to fasten hose clamps.
For EIGHTLOCK S, B and Ferrule Fittings, its sleeve is not reusable. When you reinstall a hose, please use a new one.

HAKKO Original Accessory for E-STB

Materials, Characteristics

Protective Spring Guards [Model Number: E-HSL]]

Material: SUS304 (Band, Spring and Fastener)
Spring guards prevent kinking, so you can transfer fluids safely.
E-HSL prevents kinking even if the bending radius is small due to the space-saving piping.
When you install E-HSL on the fitting, E-HSL can be used as an alternative to flat band.
