Characteristics
- UV Cut…By shielding ultraviolet, E-SJUS-BK is suitable for transferring UV-based paints, adhesives, and inks.
- Chemical Resistance…Since the inner layer is made of ETFE fluorine resin, E-SJUS-BK 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-BK is superior in flexibility. This improves your work efficiency.
- Easy Fitting Installation…Since E-SJUS-BK is very flexible, it is easier to install the tubing into the fittings.
- Hard to Break…Unlike a single-layer fluorine tubing, E-SJUS-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-SJUS-BK does not contain plasticizer (an elution material) at all. E-SJUS-BK is an oil-free tubing.
- Non-PVC…E-SJUS-BK is made of a non-PVC material.
- 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.
- 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. [Only for E-SJUS-4×6-BK and E-SJUS-6×8-BK]
■ Certificates and Regulations

Cautions:
- In case you have to use your fittings other than our original fittings, 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-SJUS-BK, 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-SJUS-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.
- We do not have our original fittings for “Flexible Fluorine (ETFE) Resin Tubing Black (Ultra Soft Type) Inch Sizes” [E-SJUS-1/8″×1/4″-BK and E-SJUS-1/4″×3/8″-BK]. If you need our technical support in fittings, please fill out this form.
Frequently Asked Question
Question: E-SJUS-BK is a multi-layer tubing. Is it easier to peel off the layer?
Answer: No. Even though E-SJUS-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-SJUS-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: “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-BK is much more flexible than E-SJ-BK.
(D) Flexibility Difference Image (E-SJUS-BK vs. E-SJ-BK)
(E) Outer Layer Surface Smoothness Test (E-SJUS-BK vs. E-SJ-BK)
Background: Polyurethane resin has a feature of great abrasion resistance, but it has a feature of grip feeling. Thus, work efficiency becomes lower due to the adhesion of a tubing.
Testing Methods: Tie a tubing of E-SJ-BK and E-SJUS-BK, make its radius to 100mm, and then hold with an air chuck at both ends. After holding, measure the resistance value when the air chuck is pulled at the certain speed. Please see the picture below.
Results: The outer layer resistance value of E-SJUS-BK is about one-fifth smaller than that of E-SJ-BK. This indicates that E-SJUS-BK shows higher outer layer smoothness than E-SJ-BK, which greatly improves the work efficiency. This is due to the fact that an outer layer of E-SJUS-BK uses a soft, smooth grade of polyurethane.
(F) 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.
