Characteristics

High Flexibility...Due to the use of soft PU, E-SNF is a professional air hose which is very flexible and easy to handle.
Smoothness...The surface of the hose is smooth and the hose is less likely to get stuck anywhere. This greatly improves your work efficiency.
No Bounce Back...E-SNF is less likely to curl and bounce up. As a result, E-SNF will not get caught on your feet.
Duration...Polyurethane resin is strong in abrasion resistance. Thus, E-SNF is suitable for air tools such as air driver.
Cold Resistance...Polyurethane resin is great at cold resistance. Thus, even though temperature reaches around minus 20$^\circ$C, E-SNF does not get harden, keeping the work efficiency.
Lightweight...Compared with a rubber hose, E-SNF is a lightweight hose, reducing the burdens of your wrestles and arms.
Safety...Even under the dim area, a hose color (pink color) stands out. Do not worry about being caught by foot.
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.

Certificates and Regulations

RoHS Compliant...E-SNF is compliant with RoHS requirements (Directive: (EU) 2015/863). (RoHS Compliant means that E-SNF 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.
EU REACH and UK REACH...E-SNF is compliant with REACH SVHC 31st list (242 substances). Certificate is available on request.
Non-Use of UV-328...E-SNF does not contain UV-328. Certificate is available on request.

Cautions:

Due to the yarn-reinforced 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" of E-SNF is also downloadable here.)

Frequently Asked Question

Question: What is the difference between E-NF and E-SNF?
Answer: E-SNF is softer than E-NF. Thus, it is easier to use without being caught around the corner.

(B) Comparative Weight Chart between E-SNF and Rubber Hose in the Market

Model Number	I.D. $\times$ O.D.	Weight per Meter
E-SNF-6.5	6.5 mm$\times$10 mm	55 g
E-SNF-8.5	8.5 mm$\times$12.5 mm	76 g
Rubber Hose A	6.3 mm$\times$13.0 mm	160 g
Rubber Hose B	7.9 mm$\times$15.0 mm	190 g

(C) Flexibility Comparative Data (E-NF vs. E-SNF)
e-snf_Flexibility Test Data

Test Method:

1: The sample is heated in a thermostatic chamber, which makes it straight.

2: Remove the sample from the chamber and leave it for 1 hour until it reaches the test temperature (23$^\circ$C ± 3$^\circ$C).

3: Set the tensile testing machine as shown above. Bend the sample into a U-shape. The "d" distance is 80mm for E-NF-6.5 and E-SNF-6.5 and 110mm for E-NF-8.5 and E-SNF-8.5.

Results:

Model Number	Bending Stress Value (N)
E-NF-6.5	3.28
E-SNF-6.5	2.08
E-NF-8.5	3.60
E-SNF-8.5	2.36

The bending stress value of E-SNF is about two-thirds as large as that of E-NF. Thus, we confirm that E-SNF is much softer and easy to use.

HAKKO Original Fittings for E-SNF

Product Name	Materials, Characteristics
Push-to-Connect Fittings for Air Hose Series [Model Number: E-RSS/E-RSP]]	Socket and Plug are connectable without effort. The spring part prevents the twisting of the hose due to the rotary function. Lock function of the socket prevents the hose from hooking off the plug.
