• Manufacturing Equipment of Chemicals, Waste Oil, Waste Fluids and Organic Solvents

Functions

Characteristics

• Standardization…Unlike using the hose clamps, you no longer worry about the positioning of the hose clamp, torque controlling and re-tightening. Anyone can insert the fittings easily.
• Possible to Install on Site…You can cut a hose and assemble a hose on site.
• Reusable…EIGHTLOCK is reusable except sleeve. If the hose is damaged, you can only replace a hose and sleeve into new ones. EIGHTLOCK is still reusable. Thus, compared with Ferrule Fittings (Swage Type), EIGHTLOCK is a cost-effective fittings. For more information on sleeve, please visit E-EL: Sleeve for EIGHTLOCK Fittings.
• RoHS2…E-ELS is compliant with RoHS2 requirements (Directive: (EU) 2015/863). (RoHS 2 Compliant means that E-ELS does not contain RoHS 2 10 restricted substances or it does not exceed the upper threshold of RoHS 2 10 restricted substances.) Certificate is available on request.
• Non-Use of UV-328…E-ELS does not contain UV-328. Certificate is available on request.

HAKKO Original Fittings for E-ELS

Product Name	Materials, Characteristics
EIGHTLOCK S Fittings [Model Number: E-ELS]]	Material: SUS304 (Body, Ring, Nut), POM (Sleeve) Our Nut Type Original Made-in-Japan Fittings Since the inner layer of the fltting is flat and does not use the rubber packing, fluid accumulation is unlikely to occur. Thus, it is easy to wash out. Since you do not need hose clamp and the controlling torque value, you can standardize how to install the fitting.

• EIGHTLOCK SERIES [E-ELS, E-ELB, E-ELF and E-ELF-PFA] are designed for HAKKO hoses.
• Please use EIGHTLOCK SERIES only the following hoses. Please do not use other hoses, which might cause leaking, coming off from the fittings, and bursting.

Applicable Hose:
Flexible Fluorine (PVDF) Resin Yarn Reinforced Hose [E-PDB]
Flexible Fluorine (ETFE) Resin Yarn Reinforced Hose [E-SJB]
Flexible Fluorine (ETFE) Resin SUS Spring Wire Hose [E-SJSP]
Flexible Fluorine (ETFE) Resin SUS Spring Wire Hose (Dissipative Type) [E-SJSD]
PRESSURE HOSE [E-TB]
Oil-Proof PRESSURE HOSE [E-STB]
SUNFOODS HOSE [E-SF]
KY SUNFOODS HOSE [E-KYS]
KY COIL HOSE [E-KYC]

• For information on chemical resistance data of EIGHTLOCK SERIES, please refer to the CHEMICAL RESISTANCE DATA.
• When you use for the first time, please wash out our fittings carefully. (We do not sterilize fittings when we shipped out from our warehouse.)
• When you use for transferring food, please do not soak fittings and hoses into the fluid. Due to the leftover, this might cause the bacteria to grow. As a result, the fittings corrode.
• When you install hose with fittings (such as installing a hose and tightening a nut), please conduct this at room temperature (20$^\circ$C $\pm$ 10$^\circ$C). When you install at low temperature, the thread portion of the fittings is likely to gall. On the other hand, when you install at high temperature, this might lower the pressure resistance.
• When you reuse EIGHTLOCK SERIES, please do not use a cutter or knife in taking ths hose off. This might damage the nipple of the fittings. Please cut the hose shortly and take it off by a pair of pliers. Also, if you find any damages or burr on the surface of the nipple, please do not reuse the fittings. This damages the surface of the hose and leads to the bursting and leaking. Please check whether or not the body and the nut do not have any irregularities. If there are any irregularities, please stop using the fittings.
• When you install a hose, please make sure the insertion point and the directions of ring and sleeve.
• For KY SUNFOODS HOSE, be careful that working pressure and temperature range of KY SUNFOODS HOSE equipped with EIGHTLOCK are not the same as those of KY SUNFOODS HOSE without EIGHTLOCK.
• When you reuse EIGHTLOCK Series, please use a new sleeve. Sleeve is not reusable.
• When you use “Flexible Fluorine (ETFE) Resin SUS Spring Wire Hose” [E-SJSP], please make sure to ground the built-in SUS spring wire. If you do not ground, SUS spring wire will become suspended conductors to accumulate and discharge static electricity, resulting in danger of causing fire.
• When you use “Flexible Fluorine (ETFE) Resin SUS Spring Wire Hose (Dissipative Type)” [E-SJSD], please make sure to firmly tighten the fitting and the nut without any space. If there is any space, the nut will become suspended conductors to accumulate and discharge static electricity, resulting in danger of causing fire. Also, when you install and conduct regular inspections, please make sure the conductivity (less than 1MΩ) between the fitting and the nut.
