1. Due to the laminated structure hose, please use the joints to seal an inner surface of the hose.
  2. 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.
  3. When you use our products, please refer to "Precautions for Use." ("The Precautions for Use" is also available at the product specifications of E-KYS, which can be downloadable from here.)
  4. In terms of chemical resistance, please refer to "Chemical Resistance Data."
  5. 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.

Case Study

Problem: Black Mold Contamination to the Final Product

Company A, manufacturing alcohol gel, has been using PVC hoses to fill in the cooling gel. However, the black mold appeared on the final product. After their investigation, it turned out that the black mold came from the plasticizer that PVC hoses have. Company A needs to look for the alternative product.

HAKKO Solution:

HAKKO proposed E-KYS: KY SUNFOODS HOSE and provided a sample. E-KYS is made of non-PVC materials, and does not contain any plasticizer. After 6 months’ trial, Company A confirmed that there was no black mold on the final product. Company A was very satisfied with E-KYS and decided to adopt E-KYS for all pipes of cooling gel in their factory.

Frequently Asked Questions

Question: We are a machine maker. We would like to use a 30-meter of E-KYS-25 for each machine, but the standard length is 50 meter. Could you make the standard length longer to 60 meter?
Answer: Yes. We can manufacture a longer standard length of E-KYS-25. Please fill out the form.

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-KYS 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. However, some types of chemicals are still 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.)
