EVIL ENERGY 3/8" Transmission Cooler Hose 5FT

EVIL ENERGY's 3/8" transmission cooler hose is a reinforced, SAE J1532-compliant line designed to carry transmission, engine, hydraulic and power steering fluids safely at up to 250 PSI.

This hose is built for cooling circuits and fluid-transfer runs where durability, flexibility and consistent internal diameter matter. Constructed with an NBR inner tube, polyester fiber reinforcement and a CPE outer cover, it balances chemical resistance and mechanical strength across a wide temperature span. The hose comes in a workable 5-foot length and meets the dimensional and performance expectations for modern transmission and power steering cooling systems.

How does this hose handle pressure and temperature extremes?

The EVIL ENERGY 3/8" hose is rated for a working pressure of 250 PSI with a burst pressure up to 1000 PSI, giving a wide margin for transient spikes. It is formulated to operate from -40°F to 257°F, so it stays flexible in cold starts and resists softening at high operating temperatures.

• Working pressure: 250 PSI for steady operation
• Burst pressure: 1000 PSI safety margin
• Operating temperature range: -40°F to 257°F

Will this fit my vehicle’s transmission cooler or power steering loop?

The hose has a nominal inner diameter of 3/8 inch (9.5 mm) with tight manufacturing tolerance and an outer diameter around 0.63 inch (16 mm), making it suitable for many OEM and aftermarket cooler lines. Clamp compatibility is broad—fitment covers 16–25 mm hose diameters—so standard clamps and fittings can secure it in place.

• Inner diameter: 3/8 in (9.5 mm) ±0.4 mm
• Outer diameter: 0.63 in (16 mm) ±0.5 mm
• Clamp range: fits 16–25 mm hose diameters

What fluids and systems is this hose compatible with?

The hose’s inner NBR tube and CPE outer cover are chosen for broad compatibility with typical automotive and industrial fluids. It is suitable for transmission fluid, hydraulic oil, engine oil, lubricants and power steering fluid, making it a versatile choice for cooling and fluid-return circuits.

• Compatible with transmission and power steering fluids
• Suitable for engine oil, hydraulic oil and general lubricants
• Designed for use in oil cooling and return lines

How easy is it to route and install this transmission cooler hose?

With polyester fiber reinforcement, the hose holds shape and resists kinking while maintaining flexibility for routing. The minimum bend radius is specified to keep internal flow unobstructed; use proper clamps and avoid sharp edges during installation to preserve service life.

• Length provided: 5 ft, suitable for many cooler runs
• Minimum bend radius: 5.03 in (128 mm) to prevent flow restriction
• Reinforced construction for kink resistance and longevity

Who is this for? Mechanics, fleet technicians and DIY vehicle owners who need a reliable 3/8" transmission or power steering cooler hose will find this hose engineered for dependable performance. Choose this EVIL ENERGY hose when you require a compact 5-foot line that meets SAE J1532 standards, stands up to a wide temperature band and is compatible with a range of automotive oils and hydraulic fluids. It’s a practical replacement or upgrade for cooling circuits where pressure capacity, chemical resistance and installation flexibility are priorities.
