Precautions to ensure safe usage
The precautions given below are intended to ensure safe and correct use of the products.
Note that certain restrictions apply to use of these products. Failure to observe these could result in injury or property damage.

Warning A potentially hazardous situation which could result in death or serious injury.
Caution A dangerous situation which could result in minor or medium injury and/or in which only property damage is foreseen.
Warning TOYOX products have been developed and manufactured for general industrial applications.
For applications that require safety, conﬁrm in advance.
Never use for implant or injection application or other applications where there is a possibility of the product partially remaining in the body.
Toyox makes no guarantee of the adaptability or safeness related to such applications.
Please read the Handling Precautions carefully before use.
Note: See the terminology glosses on our website for words marked with a ※.

TOYORING-F Hose
1

Notes for using the hoses
1. The hose can be used for water, drinking water, foods, air, chemicals, and powder. ※Do not use for fuel oil (heavy oil, kerosene (light oil),kerosene (lamp oil), gasoline) or solvents.
2. Liquid left inside hoses may be aﬀected by a plastic smell, making them unsuitable for use. Always check beforehand.
3. Clean the inside of the hose before using it to transport drinking water or food. (Clean the hose with hot water (80°C or below) for 30 minutes or less at 0.1 MPa pressure or less. )C. Depressurization deformation temperature is the temperature at which the hose deforms when
4. Use the hose within the range of -5 〜 70°its interior (in a straight condition) is depressurized to -0.1 MPa (-760 mmHg). It is not the hose's use limit temperature.
5. Use the products within their working pressure range. ※ -0.1 MPa is an approximate value. With certain applications and conditions(temperatures and movements), 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.
6. Please note that compounding agents such as ※2 plasticizers could be extracted / eluted from the hose depending on use conditions.
Please conﬁrm the use conditions and the eﬀects on your products before use.
7. Use hoses at bend angles larger than their ※3 minimum bending radius. Angles smaller than the minimum bending radius may result inhose overbending or lower pressure resistance.
8.

Warning Do not allow anything other than the inner surface of the couplings or hose to come in contact with ﬂuids (food, etc.), because
the ﬂuids may permeate the hose reinforcement layer or remain inside the couplings, and bacteria may propagate (attach tothe parts) or the hose may deteriorate. Also, dust, hose fragments (reinforcement material) and ink adhering to the outersurface may be mixed in.

9. Powders and granular materials may cause wear. Use a hose with as large a bending radius as possible.
10. Keep the hose away from open ﬂame.
11. The life of hoses will be greatly aﬀected by the physical properties, temperature, and ﬂow rates of the ﬂuid as well as by the frequency of pressurization anddepressurization. If any of the following problems or similar signs are found in the pre-work or regular inspections, immediately cease use and replace the hose.
○ Abnormalities near the ﬁtting: Localized stretching, bending, leakage, bulging, or shallow insertion into the nipple○ External damage: Large scratches in the outer surface, cracking, or water inﬁltrating the reinforcement layer○ Internal abnormalities: Bulging or ※5 separation of the inner surface, or wear that leads to exposure of the hose reinforcement material.
Note: In the case of abnormalities on the interior or exterior surface, hose scrapings and fragments of hose reinforcing materials
may mix into the ﬂuid inside the hose.
○ Other abnormal changes (stiﬀening, ※6 swelling, cracking, bulging, discoloration of the reinforcement layer, etc.)

2Notes for storage

1. Do not store outdoors or in a place subject to direct sunlight. This may cause the quality of the hose surface to deteriorate, becoming sticky and/orsusceptible to cracking. Store in a low-humidity, well-ventilated place. Store keeping the inside of the hose free from foreign matter and dust.
2. Do not store where the hose will make contact with other PVC products or near rubber products.

3Notes for disposal

1. Do not incinerate the hose. The incineration may generate toxic gases or damage incinerators; therefore, the hose should be treated asindustrial waste for disposal purposes.
2. The hose should be disposed of in accordance with the requirements of the local region.

4Notes for assembly

1. Use hose nipples suitable for the size of the hose. Do not use hose nipples with damaged or rusted surfaces.
2. Take suﬃcient care when cutting hoses, as the edge of the reinforcement coil may cause injury.
3. Tightly fastening hose with wire may damage the inner or exterior surface of the hose and cause it to rupture.
4. Retighten the hose clamp as necessary. Deformation of the plastic hose clamp fastening can cause ﬂuid leakage and hose disconnection.
5. Do not use one-push ﬁttings. Hose may rupture.
6. The compression strength indicated in this brochure is based on data which was obtained from pressure tests conducted by Toyox using the hoses alone by itsown testing method. The hose may be dislocated before the hose ruptures, or another problem may occur depending on the conditions of the ﬁttings being set(the shapes of hose nipples, types of hose clamps, number of hose clamps, fastening torque and how they are crimped). Therefore, please select a safe, eﬀective
method for mounting ﬁttings to the hoses. For technological information on using ﬁttings, please make inquiries through our Customer Advice Center.
