Overview

Meet a versatile addition to the EVIL ENERGY lineup: a 5/16-inch inner diameter heater hose designed for coolant paths. Built from EPDM rubber, this 5-foot hose offers a practical balance of reach and manageability for crowded engine bays, helping you organize your cooling routes with confidence.

Key specifications

  • Size and tolerance: ID 5/16 inch (8 mm), OD 0.55 inch (14 mm); length 5 feet
  • Material: EPDM rubber chosen for flexibility and coolant compatibility
  • Performance: Working pressure 100 psi; burst pressure 300 psi; temperature range -40°F to 257°F; minimum bending radius 64 mm
  • Standard: SAE 20R3 compliant, meeting typical wall class expectations
  • Medium: Suitable for coolant, water, antifreeze and similar automotive fluids
  • Applications: Connects radiators to overflow reservoirs, supports engine cooling loops, and versatile hot water line routing

Real-world use cases

  • Route coolant between the radiator and the overflow tank in compact engine compartments for clean routing
  • Replace aging hoses in cooling systems to maintain steady fluid flow and reduce leak points
  • Fit in hot water heater connections or auxiliary cooling circuits where space is tight and bend flexibility matters

While this hose is designed for common automotive cooling fluids, its performance depends on your specific setup. Consider it a reliable option that aligns with many standard systems, rather than a guaranteed fix for every scenario. Always follow vehicle manufacturer guidelines and perform a proper fitment check after installation.

  • Flexible design: 5 ft length offers manageable routing without excessive slack
