Flexible Fluorine (ETFE) Resin Tubing Clear Inch Type [Model Number: E-SJ-inch]
Multi-Purpose / Chemical Resistance Tube | Single-layer teflon tubing is hard (stiff) and easy to break. Our Flexible Fluorine (ETFE) Resin Tubing is an alternative tubing for a teflon tubing.

- Chemical Resistance…Since the inner layer is made of ETFE fluorine resin, E-SJ is resistant to most of the chemical substances. For more information, please refer to chemical resistance data.
- Flexibility…Due to the laminated structure, compared with a single-layer fluorine tubing, E-SJ is superior in flexibility. This improves your work efficiency. Please check the video clip to see the difference in flexibility between E-SJ and a teflon tubing.
- Hard to Break…Unlike a single-layer fluorine tubing, E-SJ is hard to break. (Even if it breaks, you can restore its shape to some extent.)
- Non-Adhesiveness…Since fluorine resin is superior in water-proof and non-adhesiveness, you can wash out the fluids very easily.
- Abrasion Resistance…Fluorine resin (inner layer) shows high levels of abrasion resistance. Thus, you can even transfer chemical slurry.
- Plasticizer-Free…E-SJ does not contain plasticizer (an elution material) at all. E-SJ is an oil-free tubing.
- Non-PVC…E-SJ is made of a non-PVC material.
- Low Elution and Low Odor…Since E-SJ contains very low levels of elution and odor, it is highly recommended for use in transfers of food, beverage, and cosmetics.
- High Purity…Fluorine resin does not contain any additives such as plasticizer, so E-SJ is suitable for transferring high purity chemical fluids.
- 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-SJ enables you to check the fluid very easily.
■ Certificates and Regulations
- RoHS2…E-SJ is compliant with RoHS2 requirements (directive 2011/65/EU:RoHS2). (RoHS 2 Compliant products mean that they do not contain or below the threshold of 10 substances.) Certificate is available on request.
- EU REACH and UK REACH…E-SJ is compliant with REACH SVHC 24th list (211 substances). Certificate is available on request.
- Food Sanitation…E-SJ 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.]

- We do not have our original fittings for “Flexible Fluorine (ETFE) Resin Tubing Clear Inch Type.” When you select the fittings, 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. If you need our technical support in fittings, please fill out this form.
- When you use our products, please refer to “Precautions for Use.”
- In terms of chemical resistance, please refer to “Chemical Resistance Data.”
- Although the inner layer is made of ETFE fluorine, please make sure whether or not E-SJ is usable for high purity fluids before you use.
- 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: E-SJ-Inch is a multi-layer tubing. Is it easier to peel off the layer?
Answer: No. Even though E-SJ-Inch consists of multi-layers, the inner layer and the outer layer are greatly adhered each other. Thus, you do not have to worry about de-lamination.
Question: Can you manufacture a non-standard size?
Answer: Yes, we can manufacture a non-standard size (such as I.D. 1/16″ × O.D. 1/8″), depending on your requirements. Please fill out “Made-to-Order Inquiry Form.”
Question: E-SJ-Inch is harder than I expected. I need a softer product.
Answer: If you have already known a teflon tube, you must have realized that E-SJ-Inch is much softer than a teflon tube. However, if you still need a softer tubing than E-SJ-Inch, we also have E-SJUS: Flexible Fluorine (ETFE) Resin Tubing (Ultra Soft Type).
(A) Relationship Graph between Working Temperature and Maximum Working Pressure
(B) Flexibility Comparative Data
Results: “Amount of Deflection” is one indication of flexibility. Flexibility varies depending on hose (tubing). The larger the amount of deflection is, the more flexible the hose (tubing) is. The lower the minimum bend radius value is, the harder the hose (tubing) is. Thus, E-SJ and E-PD are much flexible than PTFE and PFA tubing.
(C) Flexibility Difference Image (PTFE Tubing vs. E-SJ)
(D) Non-Adhesiveness Comparison Data
Results: Non-adhesiveness and smoothness, which are peculiar to fluorine resin, make it easier to wash out the fluid. You can check the data about critical surface tension and contact angle against water.
Critical Surface: The surface tension of the assumed fluid which has the contact angle of zero against solid.
(E) Washability Data
Results: In comparison with a Nylon hose, Flexible Fluorine (ETFE) Resin Hose is excellent in non-adhesiveness of the inner layer, so you can reduce washing time and save cleaning solutions and labor costs.
(F) Transparency Comparison Image: E-SJ vs. PTFE Tubing
We pour the same yellow paint through both tubings and then seal both ends.
As you can see, compared with a PTFE tubing, HAKKO E-SJ is easier to see through.
