EVIL ENERGY 3/8" Transmission Cooler Hose 10 ft — SAE J1532, 250 PSI, NBR/CPE

EVIL ENERGY 3/8" Transmission Cooler Hose is a 10-foot, SAE J1532-rated line designed to carry transmission, engine, hydraulic, and power steering fluids at working pressures up to 250 PSI.

This replacement or upgrade hose offers a balance of strength, flexibility and temperature tolerance for transmission and oil cooling systems. Built with an NBR inner tube, polyester reinforcement and a CPE outer cover, it meets SAE J1532 requirements and is sized to fit most 3/8" cooler line applications. The hose accommodates typical automotive cooling and steering fluids and is engineered to resist abrasion, heat and pressure cycling encountered in modern vehicles and equipment.

What are the exact dimensions and physical limits of this hose?

The hose has an inner diameter (ID) of 3/8 inch (9.5 mm ±0.4 mm), an outer diameter (OD) of 0.63 inch (16 mm ±0.5 mm), and comes in a 10-foot length. It has a minimum bend radius of 5.03 inches (128 mm), which helps preserve flow and prevents kinking when routed through tight engine bays.

• Inner diameter: 3/8" (9.5 mm ±0.4 mm)
• Outer diameter: 0.63" (16 mm ±0.5 mm)
• Length: 10 ft (3.05 m)
• Minimum bend radius: 5.03" (128 mm)

How strong and temperature-resistant is the EVIL ENERGY cooler hose?

This hose is rated for a 250 PSI working pressure and a 1000 PSI burst pressure, delivering a safety margin for high-demand systems. It handles temperatures from -40°F up to 257°F, making it suitable for cold starts and high-heat environments near transmissions and engines.

• Working pressure: 250 PSI
• Burst pressure: 1000 PSI
• Temperature range: -40°F to 257°F (-40°C to 125°C)
• Meets SAE J1532 pressure and performance expectations

What materials are used and why do they matter for performance?

The internal tube is NBR (nitrile rubber) for chemical compatibility with oils and fluids, while the reinforcement layer is polyester fiber to resist pressure and flexing. A CPE (chlorinated polyethylene) outer cover protects against abrasion, ozone and engine-bay contaminants, extending service life.

• Inner: NBR — resists transmission, engine and hydraulic oils
• Reinforcement: polyester fiber — improves burst and flex strength
• Outer: CPE — resists abrasion, ozone and environmental wear
• Construction designed to maintain flexibility and durability under cycling loads

Will this hose fit my clamps and typical vehicle connections?

The hose fits common clamp sizes for 16–25 mm diameter fittings, covering most aftermarket and OEM clamp ranges for 3/8" lines. Its OD and flexibility make it compatible with standard hose ends, fittings and cooler assemblies used in transmission and oil cooling setups.

• Clamp compatibility: 16–25 mm diameter clamps
• Designed for standard 3/8" cooler fittings and connections
• Eases routing in tight spaces thanks to controlled bend radius
• Suitable for use with transmission fluid, engine oil, hydraulic oil and power steering fluid

Who is this for: The EVIL ENERGY 3/8" Transmission Cooler Hose is intended for mechanics, DIY enthusiasts and fleet maintenance teams needing a robust replacement hose for transmission coolers, oil coolers and power steering circuits. It suits vehicles and equipment that require SAE J1532-level performance, chemical compatibility with automotive oils, and a durable hose that tolerates heat, pressure and routing constraints.
