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-SJB, which can be downloadable from here.)
  4. In terms of chemical resistance, please refer to "Chemical Resistance Data."
  5. Although the inner layer is made of ETFE fluorine, please make sure whether or not E-SJB is usable for high purity fluids before you use.
  6. 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.

Application Examples

Example 1: Medicine Coating

When the medical tablet is produced, the tablet is usually coated by sugar. In this coating process, a mixture of ingredients (such as sugar and additives) is added. In this process, HAKKO Flexible Fluorine (ETFE) Resin Yarn Reinforced Hose [E-SJB] has been used.

Example 2: Chemical Transfer at the Polishing Process (Semiconductor Industry)

This process is to polish the surface of silicone wafer. In polishing, HAKKO Flexible Fluorine (ETFE) Resin Yarn Reinforced Hose [E-SJB] is used to apply slurry-based chemicals.

Frequently Asked Questions

Question: Why is E-SJB harder than a normal PVC braided hose?
Answer: This is because E-SJB does not contain plasticizer, which makes a hose softer. You might feel that E-SJB is harder and difficult to handle with, but if you transfer fluids such as solvents and chemicals, we strongly recommend you to use E-SJB for chemical resistance. However, some customers still request a softer version of E-SJB. In this case, we can design products as made-to-order hoses. If you are interested in made-to-order hoses, please fill out the following form.

Question: We are a machine maker. We would like to use a 30-meter of E-SJB-9 for each machine, but the standard length is 20 meter. Could you make the standard length longer to 30 meter?
Answer: Yes. We can manufacture a longer standard length of E-SJB-9. Please fill out the following form.
