TCFS type

TOYOCONNECTOR®-F Handling Manual※ Be sure to read this manual before using the connector.

Connectors designed especially for the use with TOYOSILICONE Hoses ・TOYOSILICONE-S Hoses・HYBRID TOYOSILICONE Hoses

Warning : A potentially hazardous situation which could result in death or serious injury.

This is an explaination of the "correct use" of TOYOCONNECTOR.
Similar to individually sold hoses, please be aware of the restriction on use and follow the warnings below.
If you ignore the precautions, problems may occur due to the hose becoming detached or liquid leaking.

1. When cutting a hose, please make sure that the edge face of the hose will become square-on.

2. Make sure that the hose is inserted completely into the root of the hose insertion part.
Warning When inserting TOYOCONNECTOR TCFS into hoses, never put grease on the surface
3.
of the hose insertion part. It would be a cause of hose being pulled out.
Warning Tighten the hexagonal cap nut completely.
4.
If the nut becomes loose, the hose may become detached and liquid may leak.
5. Do not cut the hose insertion part or sleeve in place with a knife or the like.
6. After attaching the hose, make sure that the hose has not become detached and fluid does not leak at
the connector.
7. Use an " Adjustable ( Power ) Wrench " for tightening the nuts. Do not use a " Pipe Wrench ". It may
damage hexagonal cap nuts.
8. Take care to avoid injury from the sharp edges of the connector.

４．Cleaning the inside of hoses ( Make certain you clean the inside of hoses. )① Clean the inside of hoses after connecting each hose.
② After cleaning, confirm that nuts for the connectors are not loose. If the nuts are loose, retighten them.

Notes for use
1. TOYOCONNECTOR-F is a hose joint used only for the following TOYOX hoses. TOYOX is not liable for any damages caused by using
TOYOCONNECTOR with any other hose including those produced by TOYOX as well as those by other manufactures as full performance
may not be achieved or maintained. ※ Hose compatibility depends on the connector.Confirm through the catalog or the homepage.
2. Use TOYOCONNECTOR within the operating temperature and pressure ranges of the applicable hose. However, use TOYOSILICONE Hoseor TOYOSILICONE-S Hose within temperature range of 140℃ or below, and use HYBRID TOYOSILICONE Hose within temperature range of130℃ or below. Use the hoses within pressure range of 0.5MPa or below.
Do not use TOYOSILICONE Hoses under negative pressure.
3. In the case of the use of the negative pressure TOYOX's hoses may not be applicable for use according to use or conditions( temperature, movement, etc. ). For electric discharge / plasma, evaporation, or other use, please exercise caution because theextraction of plasticizers and others from TOYOX's hoses is expected. Please refer to the range of vacuum pressures as a guideline for theuse of a negative pressure.
4. When using TOYOCONNECTOR-F, do not bend hoses sharply near the connectors because the inner tube may rupture.
5.
Warning Do not assemble or disassemble the connector while fluid is in the hose because the hose may become loose
and the liquid will leak.
6. Do not use the hose where there is vibration or shock. It may cause the connector to break or the hose to become detached.
7. Perform periodic inspections to make sure that the hose does not become detached and the fluid does not leak at the connection during use
period of the hose.
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 and hose fragments (reinforcement material) to the outer surface may be mixed in.
Warning Never use TOYOCONNECTOR-F for the below applications. Hoses may rupture or become loose.
9.
・ For piping such as electromagnetic valve piping, which would put impact pressure on the piping.
・ Where vibration or impact will be applied to the connector
・ Using the hose above the operating temperature limit ( 140℃ )・ Where constant tensile stress may be applied to the hoses
・ In a way that may cause static buildup ( There is a danger of electrical shocks. )□ How to attach a hose

10. Before using TOYOCONNECTOR-F, make certain to sterilize and disinfect inside the hoses.
( The hoses do not go through sterilization procedures before shipping. )11. When cleaning TOYOCONNECTOR-F, do not rub their surfaces with a hard brush or other things because doing so may damage the surfaces,and bacteria may propagate ( attach to the parts ).
Warning Products should be disposed of in accordance with the requirements of the local region.
12.

１．
Removing the hexagonal cap nut.
① Turn the hexagonal cap nut round and remove it from the nipple.
Note Please confirm that the ring clamp and nipple are not gap.
( If loosened, retighten them. The ring clamp has a left-hand screw. )２．
Deciding the hose length and aligning and cutting the hose.
① Fix the nipple to the pipe to which the hose is to be mounted.
② Then, adjusting the hose length, cut the hose so that the edge face of the hosewill become square-on. Please make sure that the hose is not pulled.

Notes for Connector Reuse and Hose Replacement
Retaining ring

Hexagon cap nut

Note This connector should not be disassembled for cleaning on a daily basis.
Warning When replacing a hose or disassembling a joint, wait until the joint is cooled down to the room temperature.
If not, you may get burned or the joint may get damaged.

1. After disassembling the joint ( by removing the hexagon cap nuts ), please make sure to use a new hose. Also, the sleeve needs be replaced
about once every five times the joint is disassembled, which may vary with the use and other conditions.

Cut position○××

Cut off the end of hoses verticallyas much as possible.

Fluid and dirt remaining on connector may possibly cause fluid leakage and hose loosening.

4. Confirm whether there is any gap between the hexagon cap nut and PVDF screw.
5. When sleeves or PVDF screws are cracked, broken, deformed, or discolored, replace them immediately with new ones.
Otherwise their performance may be impaired, e.g. they may not be able to withstand their working pressure.

6. Please do not hit a joint with a hammer and the likes.

Warning

Adjust the length of the hose by aligning the endof the PVDF screw with the end of the hose.

1. The material used for the TOYOCONNECTOR-F flow pass ( inner surface ) is SUS316L .

Note ・ Use a sharp cutter blade to cut hoses.
・ If hoses are cut diagonally, they may detach. So please cut the end of hoses vertically.
・ If threads or hose debris is sticking out from the edge face of the hose, remove it with a nipper or the like.
・ Make sure that no hose debris or threads will get into the hose.
・ Make sure that the hose length is sufficient enough to prevent the bending stress of the hosefrom being applied near the joint.
３．
Building in the joint① Remove the joint from the pipe before starting the assembling work. ( This makes it easier to do the work. )② Insert the hose into the end of the ring clamp. If the hose is not inserted
sufficiently, liquid leakage or hose disconnection may occur.
③ Tighten the hexagon cap nut and the PVDF screw three to five threads by hand.
Note ・ Be careful not to damage screw threads.
④ Please tighten the cap nuts and PVDF screw parts using a tool such as an adjustablewrench available on the market.
Note ・ Tighten sufficiently so that there will be no gap between
the hexagon cap nut and PVDF screw.
・ If tightened insufficiently, liquid leakage or hose disconnection may occur.
⑤ Fasten the hose to the pipe using a commercially available sanitary clamp.

2. When replacing hoses, do not damage nipples with a cutter or other items because doing so will be a cause of fluid leakage.
3. Before replacing a hose, always make sure to remove the fluid and dirt on the connector surface.

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 homepage ) or make inquiries to the toll-free number. Perform a similar check for the contact
of fluid onto the outer side of the joint.
2. Do not use hoses when they are twisted. Partially twisted hoses are also a danger as they may cause internal
structural damage leading to a " Burst ". Follow the examples below to take preventative measures.

Example 1 ) Twisted hose while piping

Example 2 ) Twist when bent
