EVIL ENERGY 3/8" Transmission Oil Cooler Hose 5FT 250PSI

EVIL ENERGY's 3/8" transmission oil cooler hose is a 5-foot, CPE construction line rated for 250 PSI working pressure that connects your transmission to an oil cooler with heat and oil resistance.

This 3/8" (9.5mm) inner-diameter hose is engineered for fluid transfer between transmissions and external oil coolers. Built from chlorinated polyethylene (CPE), it balances flexibility and chemical resistance for a wide range of automotive and hydraulic applications. The hose is long enough for most retrofit and replacement jobs while meeting SAE J1532-style requirements for transmission cooler lines.

What are the hose dimensions and key performance specs?

The hose measures 3/8" ID (9.5mm) with an overall OD of 0.63" (16mm) and comes in a 5-foot length. It is rated for a 250 PSI working pressure and a 1000 PSI burst pressure, providing a significant safety margin for typical transmission cooling circuits.

• Inner diameter: 3/8" (9.5mm)
• Outer diameter: 0.63" (16mm)
• Length: 5 feet
• Working pressure: 250 PSI; burst pressure: 1000 PSI

Which fluids and conditions can this hose handle?

Manufactured from CPE, the hose tolerates transmission fluid, engine oil, hydraulic fluid, lubricants and certain gases. It resists oil and heat, working across a wide temperature window so it performs reliably under engine-bay conditions.

• Compatible with ATF, motor oil, hydraulic fluids and many lubricants
• Temperature range: -40°F to 257°F (-40°C to 125°C)
• Good resistance to oil, heat and common automotive chemicals

How flexible and durable is the line for installation?

The hose is designed with a minimum bend radius that keeps it flexible enough for tight routing while avoiding kinking. CPE construction provides abrasion and ozone resistance, helping it withstand the mechanical and environmental stresses found near transmissions and radiators.

• Minimum bend radius: 85.5 mm for safe routing
• CPE material improves abrasion and ozone resistance
• 250 PSI working pressure supports everyday driving loads

How is this hose typically used in a vehicle or equipment setup?

This hose serves as the connection between a transmission cooler and the transmission or cooler assembly. It's suitable for aftermarket cooler installs, replacements of worn lines, or custom fabrications where SAE-style cooler hoses are required.

• Use for transmission-to-cooler feed or return lines
• Ideal for retrofit and replacement on cars, trucks, and ATVs
• Works in hydraulic or lubrication systems with compatible fluids

Who is this for? Mechanics, DIY vehicle owners, and small-fleet technicians who need a reliable, heat- and oil-resistant transmission cooler hose will find this EVIL ENERGY 3/8" CPE line useful. It suits anyone installing or repairing external oil coolers, replacing brittle rubber lines, or building custom fluid-routing on performance or utility vehicles. While robust, always confirm size and compatibility with your vehicle's fittings and operating pressures before installation.
