Characteristics

Chemical Resistance...Since the inner layer is made of ETFE fluorine resin, E-SJSP is resistant to most of the chemical substances. For more information, please refer to chemical resistance data.
Bending...Rust-proof SUS Steel Wire makes it difficult to be crushed or kinked, leading to high stability in its shape.
Vacuum...E-SJSP stands proof against negative pressure (can be used in vacuum conditions).
Higher Non-Adhesiveness...Since ETFE fluorine resin is superior in terms of water-proof, 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-SJSP does not contain plasticizer (an elution material) at all. E-SJSP is an oil-free tubing.
Non-PVC...E-SJSP is made of a non-PVC material.
High Purity...Fluorine resin does not contain any additives such as plasticizer, so E-SJSP 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-SJSP 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.
Hose Cap...By sealing the hose end by hose cap, the inclusion of foreign matters is prevented. E-SJSP is tightened with hose cap only in the standard length.

Certificates and Regulations

RoHS Compliant...E-SJSP is compliant with RoHS requirements (Directive: (EU) 2015/863). (RoHS Compliant means that E-SJSP does not contain RoHS 10 restricted substances or it does not exceed the upper threshold of RoHS 10 restricted substances.) Certificate is available on request.
Non-Use of UV-328...E-SJSP does not contain UV-328. Certificate is available on request.
Food Sanitation...E-SJSP 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.]
Regulation (EC) No 1935/2004 and (EU) No 10/2011...An inner layer of E-SJSP is compliant with (EC) No 1935/2004 and (EU) No 10/2011.

Cautions:

Due to the laminated structure hose, 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." ("The Precautions for Use" is also available at the product specifications of E-SJSP, 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-SJSP 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.

Application Examples

Example 1: Fragrance and Synthetic Colorants Manufacturing Plant

HAKKO Flexible Fluorine (ETFE) Resin SUS Spring Wire Hose [E-SJSP] is used for transferring hydrocarbons, alcohols, aldehydes, esters, and other kinds of chemicals. HAKKO E-SJSP is used as a replacement of silicone hose due to the fact that E-SJSP shows better chemical resistance and has longer lifetime.

Example 2: Cleaning Process (Semiconductor Industry)

In order to remove any contaminations (such as wastes and metal ions) on the surface of wafer, fluids such as high-purity acid, alkali-based chemicals (such as ammonia, hydrogen peroxide, hydrochloric acid and hydrogen peroxide) and pure water are used. HAKKO Flexible Fluorine (ETFE) Resin SUS Spring Wire Hose [E-SJSP] is used for transporting these fluids.

Frequently Asked Questions

Question: E-SJSP includes a SUS wire inside a hose, so working pressure is higher than E-SJB. Is this correct?
Answer: No. The maximum working pressure is 1.0 MPa (10 Bar) at 20$^\circ$C for E-SJB-9 - E-SJB-25, while 0.5 MPa (5 Bar) at 20$^\circ$C for E-SJSP-12 - E-SJSP-15. A SUS wire is used for withstanding negative pressure (vacuum). E-SJB is recommendable in use for higher positive pressure.

Question: We would like to know how to cut E-SJSP correctly.
Answer: Please watch this short video clip available on our YouTube Channel.

(B) Minimum Bend Radius Comparative Data: E-SJSP, E-SJB and PFA Tubing

Test Sample	Minimum Bend Radius (mm) (20$^\circ$C)
E-SJSP-15 (I.D. 15mm)	60
E-SJB-15 (I.D. 15mm)	105
PFA Tubing (I.D. 15.9mm) (Produced by Company A)	200
E-SJSP-19 (I.D. 19mm)	75
E-SJB-19 (I.D. 19mm)	135
PFA Tubing (I.D. 20mm) (Produced by Company A)	310

Results: E-SJSP is the most suitable for a confined space installation.

(C) Non-Adhesiveness Comparison Data

Resins	Critical Surface Tension (dyne/cm)	Contact Angle for Water ($\theta$)
ETFE Fluorine	22	96
PVDF Fluorine	25	82
High Density Polyethylene	31	73
Hard Vinyl Chloride	39	68
PET	43	-
Nylon	46	54

Critical Surface Tension: The surface tension of the assumed fluid which has the contact angle of zero against solid.

Results: Since the lower value of "Critical Surface Tension" and higher value of "Contact Angle for Water" show higher non-adhesivenss, ETFE fluorine material shows the highest non-adhesiveness.

(D) Washability Data

Test Conditions	Kind of Ink	Solvent-Based Inks
Washing Methods	Ink Inclusion Period	7 Days (at Room Temperature)
	Cleaning Solution	Ethyl Acetate
	Cleaning Time	20 Seconds
	Pressure	Less than 0.01MPa

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.
