Characteristics
- UV Cut…By shielding ultraviolet, E-SJ-BK is suitable for transferring UV-based paints, adhesives, and inks.
- Chemical Resistance…Since the inner layer is made of ETFE fluorine resin, E-SJ-BK 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-BK is superior in flexibility. This improves your work efficiency.
- Hard to Break…Unlike a single-layer fluorine tubing, E-SJ-BK 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.
- Plasticizer-Free…E-SJ-BK does not contain plasticizer (an elution material) at all. E-SJ-BK is an oil-free tubing.
- Non-PVC…E-SJ-BK is made of a non-PVC material.
- High Purity…Fluorine resin does not contain any additives such as plasticizer, so E-SJ-BK 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-BK 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.
■ Certificates and Regulations
- RoHS2…E-SJ-BK 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-BK is compliant with REACH SVHC 23rd list (209 substances). Certificate is available on request.
- UL94HB Equivalent…According to the third-party institution test, E-SJ-BK is confirmed as equivalent to UL94HB (Flame Retardancy Test UL94HB Horizontal Combustion Test). Certificate is available on this webpage.

Cautions:
- 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-SJ-BK 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 Question
Question: E-SJ-BK is a multi-layer tubing. Is it easier to peel off the layer?
Answer: No. Even though E-SJ-BK 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.
Technical Information
(A) Relationship Graph between Working Temperature and Maximum Working Pressure
(B) UV Screening Data
Test Sample: E-SJ-4×6-BK
UV Penetration Range: 240nm to 800nm
Test Machine: Spectrophotometer U-4100 (Hitachi, Ltd)
Result: Ultraviolet Screening 99%
(C) 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.
(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.
