EVIL ENERGY 3/8" Transmission Cooler Hose 10ft — SAE J1532, 250 PSI, oil- and abrasion-resistant

EVIL ENERGY 3/8" Transmission Cooler Hose is a 10-foot, SAE J1532-compliant line engineered to move transmission, engine, hydraulic and power steering fluids reliably at up to 250 PSI with robust NBR/polyester/CPE construction.

This transmission cooler hose is designed for demanding vehicle and equipment cooling circuits where reliable fluid transfer, flexibility and resistance to heat and pressure are essential. Built to SAE J1532 standards, the hose balances flexibility with reinforcement so it can be routed through tight engine bays while resisting abrasion, oil exposure and temperature swings from -40°F to 257°F. Whether used for aftermarket repairs, custom plumbing or routine maintenance, the EVIL ENERGY line aims to simplify installation and last longer under stress.

How strong and heat-resistant is this 3/8" transmission hose?

The hose is rated for a working pressure of 250 PSI and a burst pressure of 1000 PSI, providing a wide safety margin for most automotive and hydraulic cooling applications. Its operating temperature span covers extremes that commonly occur around engines and coolers.

• Working pressure: 250 PSI, burst: 1000 PSI.
• Temperature range: -40°F to 257°F (-40°C to 125°C).
• Reinforced polyester fiber braid for pressure and fatigue resistance.
• CPE outer cover resists abrasion, ozone and oil exposure.

What are the exact dimensions and routing limits I should know?

The hose inner diameter is 3/8" (9.5 mm) with tight manufacturing tolerances and an outer diameter near 0.63" (16 mm). A 10-foot continuous length gives flexibility for routing, and the specified minimum bend radius helps prevent kinks when navigating tight spaces.

• Inner diameter (ID): 3/8" (9.5 mm), tolerance ±0.4 mm.
• Outer diameter (OD): 0.63" (16 mm), tolerance ±0.5 mm.
• Length: 10 ft (3.05 m) continuous.
• Minimum recommended bend radius: 5.03 in (128 mm).

Which fluids and systems is this hose compatible with?

EVIL ENERGY's transmission cooler hose is formulated to work with a variety of vehicle fluids commonly routed through coolers and remote reservoirs. Its internal NBR tube resists degradation from oil-based fluids while the construction meets SAE J1532 expectations for cooler line applications.

• Suitable for transmission fluid, engine oil and hydraulic oil.
• Compatible with lubricants and power steering fluids.
• Meets SAE J1532 standards for cooler line performance.
• Works with clamp sizes that fit 16–25 mm diameter hoses.

How easy is it to install and what mounting or clamp details matter?

The hose’s flexibility and 10-foot length make it straightforward to route and trim to fit most installations. Use proper hose clamps sized for the hose outer diameter, observe the recommended bend radius, and secure the line away from hot exhaust or sharp edges to prolong service life.

• Trim to length with a clean square cut; avoid frayed ends.
• Recommended clamp range: fits 16–25 mm diameter hoses.
• Maintain the 5.03 in minimum bend radius to prevent collapse or kinking.
• Fasten away from moving parts and high-heat surfaces for durability.

Who is this for? EVIL ENERGY’s 3/8" transmission cooler hose is intended for mechanics, DIY vehicle owners, restoration projects and performance shops that need a dependable replacement or custom routing hose for transmission, engine or hydraulic cooling circuits. It’s also suited to applications where SAE J1532 compatibility and an extended temperature range are required. If you need a long, flexible line able to handle oil-based fluids under pressure and in hot environments, this hose delivers the necessary mechanical properties and installation convenience.
