Cautions:

1. We do not have our original fittings for E-SJUS-4.3$\times$6.4 and E-SJUS-8$\times$10.
2. We do not have our original fittings for E-SJUS-1/8″$\times$1/4″ and E-SJUS-1/4″$\times$3/8″. If you need our technical support in selecting the suitable fittings for these sizes, please fill out this form.
3. In case you have to use your fittings other than our original fittings, due to the laminated structure tubing, please use the joints to seal an inner surface of the tubing. Please do not use the joints to seal an outer surface of the tubing. This may result in the bursting or coming off from the tubing.
4. When you use our products, please refer to “Precautions for Use.” (“The Precautions for Use” is also available at the product specifications of E-SJUS, which can be downloadable from here.)
5. In terms of chemical resistance, please refer to “Chemical Resistance Data.”
6. Although the inner layer is made of ETFE fluorine, please make sure whether or not E-SJUS is usable for high purity fluids before you use.
7. 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.
8. White powder (Low Molecular Weight in Resin) might come out on the tubing during storage. This white powder conforms to the “Positive List System of the Revised Food Sanitation Law” (effective on June 1, 2020), so there is no safety problem. Please wipe it off before use.

Case Study

Situation: We look for a softer fluorine product like a fluorine rubber tubing.

An ink-jet printing manufacturer (called “Company A” hereinafter) was looking for a flexible fluorine tubing like a fluorine rubber tubing for better handling and confined-space installation. So far, Company A has adopted a fluorine rubber tubing, but due to the product supply shortage, Company A had to look for the alternative product.

HAKKO Solution:

HAKKO proposed E-SJUS: Flexible Fluorine (ETFE) Resin Tubing (Ultra Soft Type) and provided a sample. Company A was surprised that E-SJUS, a non-rubber fluorine tubing, is so soft. Company A conducted the ink matching test, and it turned out that the result of E-SJUS is better than that of fluorine rubber tubing. They decided to use E-SJUS for their ink-jet printing machine.
