TOYOCONNECTOR-F Stainless Steel (TOYOX Hose Dedicated Coupling)1

Notes for installation
1. When cutting a hose, make sure that the edge face of the hose is cut perpendicularly.
2.

Warning When inserting hoses, never apply oil, etc., to the surface of the nipples.
It may cause the hose to become disconnected.

3. Make sure that the hose is inserted completely into the root of the nozzle.
4.

Warning Fasten the cap nut until there are no gaps.
When used in a state where there are gaps, trouble due to ﬂuid leakage and hose disconnection will occur.
As well, be careful to avoid injury due to wrench slips when fastening nuts.

5. Do not use a blade to cut the hose nozzle or sleeve.
6. After installation, conﬁrm that before use that there is no ﬂuid leakage or hose disconnection from the coupling area.
7. Use a monkey wrench for tightening. Do not use a pipe wrench.
It will damage the cap nut.
8. During installation, take care to avoid injury from the sharp edges of the coupling.

Notes for safe usage
1. TOYOCONNECTOR-F is a coupling dedicated for the TOYOX Hoses below. TOYOX is not liable for any damages caused by use with any otherhose including those produced by TOYOX as well as those by other manufacturers, as full performance may not be achieved or maintained.
(Applicable hose code: TSI, TSIS, HTSI)
2. Use within the operating temperature and pressure ranges of the applicable hose. Note that the maximum operating temperature is 140°
Cfor TOYOSILICONE Hose and TOYOSILICONE-S Hose, and 130°
C for HYBRID TOYOSILICONE Hose. Use the products within their workingpressure range up to 0.5 MPa.
Do not use TOYOSILICONE Hose for negative pressure applications.
3. With certain applications and conditions (temperatures and movements, etc.), negative pressure cannot be used.
Refer to the "Use condition reference values for TOYOX vacuum hoses" (Terms explained, Fig. 1) regarding guidelines for negative pressure use ranges.
4. Do not use a hose that is extremely bent near a coupling. This may break the inside of the hose.
5. Do not use in locations subject to vibration or impact. This may cause coupling damage or hose disconnection.
6.

Warning Do not attempt assembly or disassembly of couplings while ﬂuid is running through the hose.
This may cause ﬂuid leakage or hose disconnection.

7. Perform periodic inspections during use to make sure that hose disconnection from the coupling and ﬂuid leakage do not take place.
8. Do not allow anything other than the inner surface of the couplings or hose to come in contact with ﬂuids, because the ﬂuids may
permeate the hose reinforcement layer or remain inside the couplings, and bacteria may propagate (attach to the parts) or the hose may
deteriorate. Also, dust, hose fragments (reinforcement material) adhering to the outer surface may be mixed in.
9.

Warning Do not use this connector for piping other than the applications below. This may cause hose rupture or hose disconnection.
・For piping such as solenoid valve piping, which would put impact pressure on the piping ・Where vibration or impact will be applied to the coupling・Where the maximum operating temperature range exceeds 140°
C・Where constant tensile stress may be applied to the hoses
・In a way that may cause static buildup (electric shock hazard)

10. Before use, be sure to disinfect and sterilize the interior of the hose. (Sterilization is not carried out before shipping)
11. Do not rub the hose surface with a hard brush, etc., when washing it. This may damage the surface, causing germs to accumulate.
12.

3Warning The metal sections should be disposed of in accordance with the requirements of the local region.
Handle your plastic waste as industrial waste; it is not suitable for incineration disposal, as incineration generates harmful gases.

Notes for the reuse of couplings and replacement of hoses
Caution This coupling is not for routine disassembly cleaning.
Warning Hose replacement and coupling disassembly must be performed after the coupling is cooled to room temperature.
There is a risk of burns or damage to the couplings.
1. When you disassemble a coupling (cap nut removed), be sure to use a new hose.
As well, while it may vary according to conditions of use, consider ﬁve disassemblies a rough guideline for the need for replacement with a
new sleeve.
2. Do not damage the nipple surface with a knife or similar tool while replacing the hoseor it may cause liquid to leak.
3. Before replacing a hose, always make sure to remove the ﬂuid and dirt on the coupling surface.
This may cause ﬂuid leakage or hose disconnection.
4. Use a soft brush to wipe foreign matter such as dust and debris oﬀ cap nuts and PVDF screws.
5. If the sleeve or PVDF screws develop a crack, damage, deformation or discoloration, immediately replace with new partsor full performance may not be achieved.
6. Do not hit the coupling with a hammer or similar tool.

4Warning
1. The ﬂuid path (interior) of TOYOCONNECTOR uses SUS 316L material.
Phenomena such as corrosion or ﬂuid leaks may occur depending on the type of ﬂuid.
Before use, be sure to check data (refer to data on chemical resistance in the catalog or on the website) or make inquiries to the toll-freenumber.
As well, make similar checks for ﬂuid contact with the outer surface of couplings.
2. Do not install or use twisted hoses. Twisted hoses are dangerous because they deform their interior structures and cause hose ruptures.
Fix twisted hoses appropriately as shown in the following examples.
Example 1: Hose twisted when it is installedOK

Not allowed(Measures taken)

Example 2: Hose twisted when it is bent
