EVIL ENERGY 1-Inch Silicone Heater Hose – 10 ft, SAE J20R3 Class-A, 60 PSI, Black

Overview

Meet the EVIL ENERGY 1-Inch Silicone Heater Hose, a flexible, temperature-ready coolant path designed for automotive and home systems. With its 10-foot length, it helps you route coolant, steam, or air where you need it, within safe operating boundaries defined by SAE J20R3 Class-A standards. The black braided hose pairs durability with a clean, professional look in crowded engine bays and water heater closets.

What makes it stand out

• Size and fit: Inside diameter 1" (25.4 mm); outside diameter 1-3/8" (34.4 mm); length 10 feet; tolerance ±0.4 mm per spec.
• Performance: Working pressure 60 psi; burst pressure 174 psi; temperature range -67°F to 356°F (-55°C to 180°C); minimum bend radius 127 mm.
• Materials: Braided polyester fiber and silicone inner/outer layers offer higher temperature tolerance and longer life compared with EPDM alternatives.
• Applications: Suitable for automotive cooling systems, heating systems, water heaters, and other coolant or air transport needs. Not suitable for alcohol, fuel, engine oil, or lubricants.

Real-world use scenarios

In a car, this hose can become part of a durable radiator or heater circuit, handling hot coolant even on hot summer days. In a home or workshop, it may serve within a water heater feed or a makeshift heating loop, where flexibility and resilience matter. The outer braiding protects against abrasion in busy engine bays, while the silicone layers resist cracking and hardening across cycles.

Installation tips

• Trim squarely: Cut the hose squarely to avoid leaks and ensure proper clamp seating.
• Avoid sharp bends: Maintain a bend radius near or above 127 mm to prevent kinking.
• Match fittings: Check hose ID/OD and clamp compatibility before installation.
• Safety: Do not use with alcohol-based fluids, fuel, engine oil, or lubricants.

How this helps your project

Whether you are upgrading an aging cooling loop or configuring a new heating circuit, the EVIL ENERGY silicone heater hose offers a robust balance of flexibility and heat resistance. The long 10-foot length gives you extra routing freedom in tight spaces, while the silicone construction supports stable performance across a wide temperature range.
