Characteristics

Vacuum...E-KYC stands proof against negative pressure (can be used in vaccum conditions).
Stability...Resin Coil makes it very difficult to be crushed or kinked, leading to high stability in its shape.
Non-PVC...E-KYC is an eco-friendly tubing, which is made of Olefin Resin and Styrene Resin.
Environment-Friendly...E-KYC restrains the production of harmful gas, even though it is burned out.
Plasticizer-Free...E-KYC does not contain plasticizer (an elution material) at all.
Low Elution and Low Odor...Compared with PVC hose, elution levels are low. It is suitable for transferring food, beverage and cosmetics.
Chemical Resistance...Since the inner layer is made of Olefin Resin, E-KYC shows great chemical 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-KYC (natural 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-KYC is compliant with RoHS requirements (Directive: (EU) 2015/863). (RoHS Compliant means that E-KYC 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-KYC does not contain UV-328. Certificate is available on request.
Food Sanitation...E-KYC conforms to the Food Sanitation Law No.370 (No.370 of the Ministry of Health and Welfare for Food Sanitation). (Conformity to N-Heptane). [Regarding the conformity of “Partial Revision of the Food Sanitation Law” (Effective on June 1, 2020) and Positive List System (PL), please download here.]

Cautions:

Due to the laminated structure 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.
When you use our products, please refer to "Precautions for Use." ("The Precautions for Use" of E-KYC is also downloadable here.)
In terms of chemical resistance, please refer to "Chemical Resistance Data."
Although the inner layer is resistant to fluids, depending on working environments, the fluids would be permeated through the inner layer, resulting in the danger of swelling and degradation of the middle or outer layer.

Frequently Asked Questions

Question: How do we wash out the food grade hose?
Answer: To wash out the inner layer of the hose, we recommend you to use a sponge ball and rocket brush.

Question: We understand that an inner layer of E-KYC is made of Olefin. What kinds of chemical can be transferred through Olefin?
Answer: Although in terms of chemical resistance, Olefin is lower than Fluorine, some types of chemicals are transferrable. For instance, isopropyl alcohol, phenol, alkali, methanol, ethanol, and sodium hypochlorite are transferrable. (Please note that depending on the other using conditions, those chemicals might not be resistant against Olefin. Please check in advance.)

HAKKO Original Fittings for E-KYC

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 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.

EIGHTLOCK Ferrule Fittings with PFA Lining [Numéro de Modèle: E-ELF-PFA]]	Matériau: Corps: SCS16, Partie en contact avec le fluide : Revêtement PFA, écrou et bague : SCS13 (manchon : POM) Grâce au revêtement en PFA, vous pouvez transférer des fluides qui ne sont pas possibles avec des raccords métalliques. Vous pouvez remplacer un tuyau même si le tuyau a besoin d'être remplacé, car le raccord EIGHTLOCK est un raccord à bague à écrou. Vous pouvez installer et démonter le raccord sur place. Vous pouvez utiliser une large gamme d'usages tels que les tuyaux pour les produits chimiques, les aliments, les boissons et l'alcool. L'extrémité de la tétine est moins susceptible d'accumuler des liquides, de sorte que vous n'avez pas à vous soucier beaucoup de la contamination.

Cautions:

For EIGHTNIPPLE S and B Fittings, please fasten with two hose clamps.
For EIGHTLOCK S, B and Ferrule Fittings, its sleeve is not reusable. When you reinstall a hose, please use a new one.
Working temperature range with EIGHTLOCK S, B and Ferrule Fittings is not the same as without EIGHTLOCK S, B and Ferrule Fittings. For more information, please visit the product page of EIGHTLOCK Fittings.

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.
