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.
