TOYOCONNECTOR TC3-CS 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. Make sure that the hose is inserted completely to the root of the nozzle.
3.

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

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 or 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 with TC3-CS gasket.
6. After installing, 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. Take care to avoid injury from the sharp edges of the coupling.
9. Be careful that incompatible chemicals do not adhere to the rubber components used in the couplings.

2Notes for connecting couplings
1. Select the main unit and gasket materials suitable for the ﬂuid used.
2. Chemicals which are dangerous when permeating (active gases) should not be used in gaseous form.
3. Use the products within their intended working pressure range.
4. Do not apply external force (e.g. impact) to the body and cam arm. This may cause damage.
5. Avoid pulling or dragging the hoses on the ﬂoor. Doing so may cause the cam arms to catch against an object and unlock.
6. Avoid applying loads on joints. This may cause ﬂuid spills.
7. We recommend using couplers and adapters made of the same material when connecting ﬁttings.
Using couplers and adapters made of diﬀerent materials may lead to corrosion (electrical corrosion).
8. Dismantle the coupler connection only after conﬁrming that there is no residual pressure or materials.
9. To avoid burns during use with high-temperature ﬂuids, avoid direct contact with the coupling.
10. Wear gloves and safety shoes to prevent injury during installation and operation.
11. When vertically installing the coupler, position it on the lower side of the adaptor.
12. High ﬂuid ﬂow rates may result in cavitation that abrades or damages the inner surface of the coupler. Perform inspections at the appropriate intervals.
13. When connecting the coupler, chip dust may transpire due to cam arm tightening. Remove chip dust before use.

Notes for safe usage
1. TOYOCONNECTOR is a coupling dedicated for the above TOYOX Hoses. 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.
2. Use within the operating temperature and pressure ranges of the applicable hose.
3. Do not use a hose that is extremely bent near a coupling.
The bending radius of a hose should be larger than its ※3 minimum bending radius.
4.

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

5. Do not use in locations subject to vibration or impact. This may cause coupling damage or hose disconnection.
6. Perform periodic inspections during and before use to make sure that hose disconnection from the coupling and ﬂuid leakage do not take place.
7. 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) and ink adhering to the outer surface may be mixed in.
8.

Warning Do not use for piping in 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 is exceeded
・Where constant tensile stress may be applied to the hoses
・In a way that may cause static buildup (electric shock hazard)

9. Before use, be sure to disinfect and sterilize the interior of the hose. (Sterilization is not carried out at shipping)
10. Do not rub the surface with a hard brush, etc., when washing it. The surface could be damaged, causing germs to accumulate.
11. Disposal should be in accordance with the requirements of the local region.

Notes for gaskets

Coupler

1. Before using the coupler, check to conﬁrm that the gasket ﬁts
into the coupler groove. (See ﬁgure to the right)
2. Foreign matter adhering to the gasket seat can make it hard to closethe cam arms and may lead to spills.
Inspect and remove any foreign matter.

Gasket3. Because fluorine resin type gaskets using fluorine resin ( PTFE andFEP ) lack elasticity, they may leak depending on conditions of use.
4. Assess the force required to close the cam arms when connecting or disconnecting the couplers.
If the force required is too low, the gasket seal may be compromised. In this case, we recommend replacing the gasket.
※ If closing the cam arms feels too easy even after replacing the gasket, the main unit may be damaged. If so, replace the main unit.

5Notes for inspections

1. Startup inspections: Before starting operations, check to conﬁrm that the ﬁttings are free of abnormalities and that the cam arms are fully closed.
2. Regular inspection: During periods in use, be sure to perform regular inspections.

What to do if an abnormality is foundIf you observe signs of abnormalities like those below during startup inspections or periodic inspections, stop using the product immediately.
Replace with a new product.
1. The main unit or any of the components show large scratches, cracks, deformation, or projecting pins.
(The service life of the main unit, cam arms, and gaskets depends on materials and usage conditions. We recommend replacement at periodic intervals. )2. Closing the cam arms feels too easy when connecting or disconnecting couplers.

Notes for the reuse of couplings and replacement of hoses
Caution This coupling is not designed for regular 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 reusing TOYOCONNECTOR, replace the sleeve with TC3-CS gasket with a new one.
2. Please make sure to use a brand-new hose.
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. While it may vary according to conditions of use, consider ﬁve disassemblies a rough guideline for replacing with a new coupling.
5. Do not hit the coupling with a hammer or similar tool.

Warning
1. The ﬂuid path (interior) of TOYOCONNECTOR uses SCS 14 (SUS 316 equivalent) 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-free number.
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 structuresand cause hose ruptures. Fix twisted hoses appropriately as shown in the following examples.

Example 1: Hose twisted when it is installed

Example 2: Hose twisted when it is bent
