They help prevent the accumulation of static charge, reducing the potential for sparks or ignition.

Food-Grade Polyurethane Hose:

Formulated to meet strict food-contact standards, these hoses are suitable for use in the food and beverage industry.

They are resistant to chemicals, oils, and microbial growth, ensuring compliance with food safety regulations.

Temperature-Resistant Polyurethane Hose:

These hoses are designed to withstand high or low temperatures, depending on the application requirements.

They are often used in applications involving hot or cold fluids, or in environments with extreme temperature fluctuations.

Conductive Polyurethane Hose:

Conductive polyurethane hoses are designed to dissipate static electricity and provide a path for grounding.

They are commonly used in applications where there is a risk of static buildup, such as in the handling of flammable liquids or powders.

Transparent Polyurethane Hose:

These hoses feature a clear or translucent construction, allowing for visual inspection of the fluid flow.

They are often used in applications where monitoring the fluid condition or identifying potential issues is important.

The selection of the appropriate polyurethane hose type depends on the specific requirements of the application, including factors such as pressure, temperature, chemical exposure, and the need for specialized features like anti-static or food-grade properties.
