EVIL ENERGY 1/2in Silicone Heater Hose – Straight, SAE J20R3 Class-A, 60 PSI, 5ft, Black

Overview

Meet the EVIL ENERGY 1/2 in silicone heater hose, a straight routing solution built for automotive cooling and heating paths. The braided polyester core, combined with silicone inner and outer layers, is designed to perform across a broad temperature window and endure the wear of daily use in engine bays. This profile emphasizes durability and versatility, offering a practical option for drivers seeking reliable media transport without committing to a single layout.

Key specifications

• Inner diameter: 1/2 in (12.7 mm) with a tolerance of ±0.4 mm
• Outer diameter: 13/16 in (20.7 mm) with a tolerance of ±0.4 mm
• Length: 5 feet
• Working pressure: 60 psi
• Burst pressure: 246 psi
• Temperature range: -67 F to 356 F (-55 C to 180 C)
• Minimum bend radius: 50.5 mm
• Standard: SAE 20R3 Class A

Materials and durability

The hose uses braided polyester fibers with silicone forming both inner and outer layers. Silicone provides a wider temperature window and is typically more resistant to heat and aging than EPDM compounds. The braided exterior adds reinforcement to resist kinking and abrasion in busy engine compartments.

What you can use it for

This hose is designed to transport air, steam, water, coolant, and mildly acidic or alkaline media. It suits automotive cooling and heating systems, water heaters, and other installations that require a flexible, heat-tolerant hose. The straight configuration supports straightforward routing in compact layouts.

Usage notes and care

• Not for carrying alcohol, fuel, engine oil, or lubricants
• Respect the minimum bend radius to maintain flow and reduce stress
• Pair with appropriate clamps and secure routing for reliable performance

Performance at a glance

• Broad temperature tolerance supports varied engine bay conditions
• Silicone formulation offers durability against heat and aging
• Braided exterior provides structural strength against wear
• Five-foot length enables flexible installation across different layouts

Choosing this hose means selecting a component designed to stand up to the demands of automotive cooling and heating tasks while offering practical routing options. It emphasizes versatility, safety with media limitations, and a balance of strength and flexibility for everyday use.
