• Material: EPDM rubber for reliable flexibility and wear resistance.
• Pressure and temperature: Working pressure up to 100 psi; Burst pressure around 300 psi; Temperature range from -40°F to 257°F; Minimum bending radius 152 mm. Complies with SAE 20R3 standard wall class D-2.
• Medium: Compatible with coolant, water, antifreeze, and similar fluids.
• Application: Suitable for hot water heater connections, engine cooling loops, and radiator overflow lines.

Why choose this hose?

• Durable EPDM construction supports long-term performance in varied temperatures and conditions.
• Wide temperature range makes it adaptable to seasonal changes and different climate environments.
• 20-foot length provides flexibility for routing without excessive fittings or joins.
• High working pressure and SAE 20R3 compliance offer compatibility with standard coolant circuits in many engines.

Usage ideas and scenarios

• Automotive: Connect radiator to engine or overflow reservoir for a clean, direct path of coolant.
• Residential or light-duty: Use in hot water heater connections or small cooling loops requiring a straight run.
• Maintenance: Replacing aging hoses can help maintain steady flow and reduce the risk of leaks in critical cooling paths.

Quality and care

The hose is designed to endure typical automotive cooling tasks with an emphasis on durability and reliability. Store away from direct sunlight when not in use, and inspect for kinks or signs of wear before installation to ensure a secure seal and optimal performance.

Compatibility and limits

Designed for coolant-based systems, this hose should not be used with incompatible fuels or solvents. Verify system specifications, including size, length, and fluid compatibility, before installation.
