Functions
Sanitary Fittings
Washability
SCS16
Band-less Joints
RoHS 2 Free
Characteristics
- High Corrosion Resistance...Since the wetted part is coated by PFA, you can safely transfer fluids (such as acids) that are not possible for SUS or brass fittings.
- Possible to Reuse the Fittings...Since E-ELF-PFA is a nut type ferrule fitting, it is easy to install at site. When you replace a hose, you can reuse a fitting.
- Sanitary Fittings...Because of the nipple shape, E-ELF-PFA fittings are less likely to accumulate the fluids. Thus, you can transfer the fluid in a clean manner. Also, the material of the fitting is SCS16 (equivalent to SUS316L/SS316L = Wetted Surface) has higher levels of corrosion resistance.
- Non-Rubber Packing...Since the inner layer is flat and does not use the rubber packing, there is no elution from the packing. The material of the wetted part is SCS16 (equivalent to SUS316L), which shows resistance against food, chemicals, and solvents.
- 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.
- RoHS Compliant...E-ELF-PFA is compliant with RoHS requirements (Directive: (EU) 2015/863). (RoHS Compliant means that E-ELF-PFA 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-ELF-PFA does not contain UV-328. Certificate is available on request.
Product Standard
Lining Material: PFA
Material: SCS16 (SUS316L/SS316L) (Body), SCS13 (SUS304/SS304) (Ring, Nut) and POM (Sleeve)
*Please note that sleeve is NOT replaceable. Please use a new sleeve when you assemble a hose again.
You can purchase only sleeve as a spare part. Please mention "Sleeve Code" specified in the Product Standard.
*E-ELF-PFA conforms to the Food Sanitation Law No.370 (No.370 of the Ministry of Health and Welfare for Food Sanitation) (Conformity to N-Heptane). However, E-ELF-PFA does not conform to the "Partial Revision of the Food Sanitation Law" [Positive List System (PL)].

How to Assemble EIGHTLOCK FERRULE Fittings
Technical Information
[Washability Comparison: EIGHTLOCK Ferrule Fittings vs. Conventional Ferrule Fittings sold in the Market]
*Sample
・Hose in Use: Flexible Fluorine (PVDF) Resin Yarn Reinforced Hose (E-PDB-25) I.D. 25mm $\times$ O.D. 33mm
・Fittings in Use: EIGHTLOCK Ferrule Fittings (E-ELF-25-F1S) / Conventional Ferrule Fittings (Barb Nipple Type)
(a) Hair Dye Mousse
The hair dye mousse is sealed for one hour, and after washing with tap water,
we checked the presence of fluid accumulation at the end of the nipple and the hose connection part.
: No Fluid Accumulation
: Fluid Accumulation
(b) Dental Plaque Fluid
The dental plaque fluid is sealed for one hour, and after washing with tap water,
we checked the presence of fluid accumulation at the end of the nipple and the hose connection part.
: No Fluid Accumulation
: Fluid Accumulation
[Result]
HAKKO EIGHTLOCK FERRULE Fittings could not visually confirm the fluid accumulation.
This improves the sanitation and reduces the loss of the fluid flow.

EIGHTLOCK Ferrule Fittings with PFA Lining [Model Number: E-ELF-PFA]] |
- Material:Body: SCS16, Wetted Part: PFA Lining, Nut and Ring: SCS13 (Sleeve: POM)
- Due to PFA Lining, you can transfer fluids that are not possible for metal fittings.
- You can replace a hose even though the hose needs replacement, since EIGHTLOCK Ferrule Fitting is a nut ferrule fitting. You can install and detach the fitting on site.
- You can make use of a wide range of usages such as pipes for chemicals, food, beverage and alcohol.
- The nipple end is less likely to accumulate fluids, so you do not have to worry about contamination very much.

EIGHTLOCK SERIES are designed for HAKKO Hoses!
- 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 (Ultra Soft Type) [E-SJSPUS]
Flexible Fluorine (ETFE) Resin Yarn Reinforced Hose (Ultra Soft Type) [E-SJBUS]
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.
