This will not result in damage to the hose, though it may stick to the outside surface. We cannot, however, guarantee the TOYOSILICONE Hose for uses above 70℃.

Due to the characteristics of the TOYOSILICONE Hose, it is a material with higher gas permeability (porous) than vinyl hoses. If high-temperature water exceeding 100 degrees is used, the steam of the high temperature water will permeate the inner pipe of the hose, which may easily damage the reinforcement thread and reduce the hose pressure resistance performance. The hose that can flow hot water up to 140 °C is the TOYOSILICONE Steam Hose.

Pinholes likely formed in areas where the hose material had softened and weakened due to high temperatures. If a pinhole rupture occurs, first check whether the fluid and atmospheric temperatures are within the operating temperature ranges for the hose you are using. If operating temperature ranges are exceeded, take measures such as switching to a heat-resistant hose with a more suitable temperature range. Feel free to contact Toyox for assistance in making a selection.

The cutting method will differ depending on the thickness and type of the hose. We demonstrate some of the various methods and tools in our video “How to Cut a Toyox Hose.”

The reinforcing material of the TOYOFOODS-S Hose is made of hard iron wire that’s prone to rusting. Avoiding wetting the ends while using the hose. Contact us for products that use a rust resistant reinforcing material.

In the case of polyurethane air hoses, one possible cause could be its storage in a humid warehouse for a long period of time. Although polyurethane hoses are lightweight, abrasion resistant, and oil resistant, if exposed to high temperatures and humidity for long periods of time, a phenomenon called hydrolysis can occur, which causes the entire hose to become brittle. Furthermore, although Toyox polyurethane air hoses (e.g., HITRUN and HIT Hose) are made using a urethane material that is resistant to hydrolysis, we recommend hoses be stored in a well-ventilated place subject to low temperatures and humidity.

No service life is set for our hoses. Since many usage conditions such as fluid type, operating temperature, operating pressure, hose size and length are involved and the hoses are used in a wide variety of environments, it is not possible to set a specific service life. Make arrangements based on the actual piping conditions at your company.

If a normal PVC resin hose is used with food, hot water and cleaning agents at 60℃ or higher, the hose will harden, which may lead to problems such as leakage and disconnection of the hose coupling. Depending on the pressure of food, hot water, etc., we offer hoses according to applications and usage conditions such as those that can be used up to 70℃ and 150℃. Select a hose that meets the operating conditions.

Originally, TOYORON Hoses with inner diameters of 22ø and 45ø and SUPER TOYORON Hoses with inner diameters of 22ø and 48ø were made into standardized sizes based on the assumption that they would be directly inserted into 15A and 40A hard pipes (steel pipes, PVC pipes). Therefore, there are no compatible threaded hose nipples available on the market. Furthermore, TOYOCONNECTOR is a dedicated coupling for Toyox hoses, but there are no products available compatible with its size.

Solutions of sodium hydroxide (caustic soda) should generally not be run through the TOYOSILICONE Hose as it can cause degradation of the hose. For CIP (cleaning in place), however, a dilution of 2 to 3% may be used without problems. The TOYOSILICONE has even been used by a CIP equipment manufacturer. Even so, this will result in quicker degradation than using water or air.
