Description
xOverview
This EVIL ENERGY 3/4-inch heater hose is designed to bridge coolant paths in automotive and home systems. With a 3/4-inch inner diameter, an outer diameter of 1.10 inches, and a full 5-foot length, it offers a straightforward path for radiator connections and hot water heater lines. The black EPDM rubber combines flexibility with long-term durability to handle daily heat exposure, fluid variety, and routing challenges.
Performance and durability
It supports a working pressure of 100 psi with a burst pressure of 300 psi, and it can withstand temperatures from -40F to 257F, providing resilience through extreme engine heat cycles and seasonal changes. The minimum bending radius of 152 mm helps reduce kinks and stress at corners in tight engine bays.
Standards and compatibility
The hose is compatible with coolant, water, and antifreeze. It meets SAE 20R3 standard wall class D-2, aligning with common automotive cooling circuit requirements and similar systems such as hot water setups and overflow connections.
Practical uses and guidance
Use it to connect an engine cooling path to the radiator, route coolant to an overflow reservoir, or outfit a hot water heater line. The 5-foot length supports flexible routing in many layouts, while the EPDM composition aims to withstand repeated heat exposures. For best results, check for wear, avoid sharp bends, and ensure a clean, secure fit with proper clamps.
