Do not use for an extended period of time for nonpolar organic solvents (such as benzene, toluene and hexane), halogenated hydrocarbons (such as methylene chloride and trichloroethane), concentrated strong acids, strong bases, mineral oil or steam. Also, do not use for animal or vegetable oil exceeding 70℃ under any circumstances. For steam cleaning, treat for a short time with a saturated steam pressure of less than 0.2 MPa at 120℃.

[Resistant to high heat]Handles hot fluids up to 140℃. With a long use life, reduces production problems due to hose hardening and deterioration caused by heat. Dedicated fastening couplings 3 meters in length are also available for temperature regulators.
[High insulation] Vinyl chloride is used to provide a high level of insulation, appropriate for the semiconductor and electronics industries. 
[Special reinforcement to prevent bursting] No thread unraveling or hose ruptures near the coupling due to the unique reinforced structure for safe, secure use.
[Lightweight for easy work] Lighter than ordinary rubber hoses to make work more efficient.

Note: The TOYOSILICONE THERMO 140 HOSE is compliant with the revised regulations of the RoHS 2.

Note: Use safely with a dedicated coupling to prevent liquid leaks and hose disconnections.
This reduces production problems and maintenance for higher production efficiency.
Superior heat resistance up to 140° C, not as susceptible to hardening as vinyl chloride and rubber hoses for longer use life. Excellent for various heat applications. The dedicated coupling prevents leaks and disconnections for improved production efficiency!
