Flexible Fluorine (ETFE) Resin Tubing (PVC Type) [Model Number: E-SJV]
Multi-Purpose | Chemical Resistant Soft Tube | Single-layer Teflon tubing is hard and easy to break. Our Flexible Fluorine (ETFE) Resin Tubing (PVC Type) [E-SJV] is an alternative tubing for a Teflon tubing. E-SJV is much softer than our standard E-SJ. Thus, if you feel E-SJ is a bit stiff, E-SJV is a solution for you.

- Chemical Resistance…Since the inner layer is made of ETFE fluorine resin, E-SJV 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-SJV is superior in flexibility. This improves your work efficiency.
- Hard to Break…Unlike a single-layer fluorine tubing, E-SJV 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.
- 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-SJV 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. For more information on our original fittings, please scroll down to the end.
Certificates and Regulations
- RoHS2…E-SJV is compliant with RoHS2 requirements (Directive: (EU) 2015/863). (RoHS 2 Compliant means that E-SJV does not contain RoHS 2 10 restricted substances or it does not exceed the upper threshold of RoHS 2 10 restricted substances.) Certificate is available on request.
- Food Sanitation…E-SJV 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.]
- Non-Use of UV-328…E-SJV does not contain UV-328. Certificate is available on request.

- 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.
- When you use our products, please refer to “Precautions for Use.” (“The Precautions for Use” is also available at the product specifications of E-SJV, which can be downloadable from here.)
- 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-SJV 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.
Problem: A Single-Layer Teflon Tube is hard and easy to break.
An analytical instrument manufacturer (called “Company A” hereinafter) was looking for a flexible tubing for better handling and easy installation. An inner layer should be made of fluorine, and its bending radius is smaller and hard to break. Company A is also concerned about the chemical resistance of polyurethane resin (outer layer) against the gases that fill the equipment inside.
HAKKO proposed E-SJV: Flexible Fluorine (ETFE) Resin Tubing (PVC Type) and provided a sample. The inner layer of E-SJV shows a feature of smoothness and higher levels of chemical resistance. The outer layer is made of PVC, which makes the tubing softer and more flexible. Besides, PVC shows better resistance against acid and alkali than polyurethane. As a result, compared with a teflon tubing, E-SJV is flexible, hard to break and restore its shape even if it kinks. After Company A evaluates our E-SJV, E-SJV passed the criteria of smoothness, chemical resistance (both inner and outer layers) and flexibility.

(B) Flexibility Comparative Data
*Test Temperature: 20$^\circ$C (68$^\circ$F)
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-SJV is much more flexible than E-SJ.
