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

- Chemical Resistance…Since the inner layer is made of ETFE fluorine resin, E-SJUS is resistant to most of the chemical substances. For more information, please refer to chemical resistance data.
- Flexibility and Easy Handling…Due to the laminated structure, compared with a single-layer fluorine tubing, E-SJUS is superior in flexibility. This improves your work efficiency.
- Easy Fitting Installation…Since E-SJUS is very flexible, it is easier to install the tubing into the fittings.
- Hard to Break…Unlike a single-layer fluorine tubing, E-SJUS is less likely 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-SJUS does not contain plasticizer (an elution material) at all. E-SJUS is an oil-free tubing.
- Non-PVC…E-SJUS is made of non-PVC materials.
- Low Elution and Low Odor…Since E-SJUS contains very low levels of elution and odor, it is highly recommended for use in transfers of cosmetics.
- High Purity…Fluorine resin does not contain any additives such as plasticizer, so E-SJUS 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-SJUS 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. [Only for E-SJUS-4×6 and E-SJUS-6×8]
■ Certificates and Regulations
- RoHS2…E-SJUS 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-SJUS is compliant with REACH SVHC 23rd list (209 substances). Certificate is available on request.
- Food Sanitation…E-SJUS 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.]

- Due to the laminated structure tubing, 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.”
- 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-SJUS 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.
- We do not have our original fittings for Flexible Fluorine (ETFE) Resin Tubing (Ultra Soft Type) Inch Sizes.
Frequently Asked Question
Question: E-SJUS is a multi-layer tubing. Is it easier to peel off the layer?
Answer: No. Even though E-SJUS consists of multi-layers, the inner layer and the outer layer are greatly adhered each other. Thus, you do not have to worry about delamination.
(A) Relationship Graph between Working Temperature and Maximum Working Pressure
(B) Flexibility Comparative Data
Results: “Bending Stress Value” is one indication of flexibility. Flexibility varies depending on hose (tubing). The larger the value of bending stress is, the more flexible the hose (tubing) is. Thus, E-SJUS is much more flexible than E-SJ.
(C) Flexibility Difference Image (E-SJUS 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.
