KY TUBE [Model Number: E-KYT]

Cautions:

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.”
In terms of chemical resistance, please refer to “Chemical Resistance Data.”
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: We understand that an inner layer of E-KYT is made of Olefin. What kinds of chemical can be transferred through Olefin?
Answer: Although in terms of chemical resistance, Olefin is lower than Fluorine, some types of chemicals are transferrable. For instance, isopropryl alcohol, phenol, alkali, methanol, ethanol, and sodium hypochlorite are transferrable. (Please note that depending on the other using conditions, those chemicals might not be resistant against Olefin. Please check in advance.)

Technical Information

(A) Relationship Graph between Working Temperature and Maximum Working Pressure

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-KYT is much more flexible than E-PD and E-SJ tubing.

Item	KY TUBE	PVC TUBE	POLYETHYLENE TUBE	Determination Limit
Non-Ionic Surfactant	No Detection	1	No Detection	0.005mg/L
Phenol	3	0.014mg/L	0.0005mg/L
Total Organic Carbon	0.1	No Detection	0.3mg/L

Notes: Depending on the materials of the hose, plasticizer and stabilizer may elute. Data on the above show the levels of low elution of E-KYT. The results above are measured values are NOT guaranteed.

If you wash the hose in hot water, hot water must be lower than 80 $^\circ$C (176 $^\circ$F), less than 30 minutes and less than 0.1 MPa (1kgf/cm²) (One-Side Free Condition).

Product Name	Materials, Characteristics
Fittings for Multi-Layer Tubing [Model Number: E-FTS-F]]	Material: SUS316L (Body) and SUS304 (Nut) It is designed by HAKKO tubing products, so you do not have to worry about fluid leakages and coming off. Specify temperature range and working pressure for each product. It is excellent in corrosion resistance (Body: made of 316L Steel Use). Since it is made of stainless steel (Passivation Treatment), you can transfer a wide variety of fluids.

PEEK (Carbon Reinforced) Nut Type Fittings [Model Number: AL]]	Material: PEEK Lightweight…Fitting weight is less than one-fifth, compared to same-size SUS joints, leading to overall weight reduction of equipment. Great Heat Resistance…PEEK material has excellent heat resistance among resins. Chemical Resistance…PEEK material has excellent resistance to a wide range of chemicals including acids, alkalis and organic solvents. Mechanical Strength…Carbon fiber is added to the engineering plastic of PEEK, which is strong in tensile and impact resistance.
