EVIL ENERGY 3/8" Transmission Oil Cooler Hose 10ft — 250 PSI CPE, -40°F to 257°F

This hose is engineered to provide a durable, flexible connection between an oil cooler and transmission or other fluid systems. Built from chlorinated polyethylene (CPE), it balances chemical resistance and temperature tolerance for automotive and light industrial uses. The 3/8" inner diameter and 10-foot length make it suitable for many retrofit and replacement needs while meeting SAE-style performance expectations.

What are the key performance specifications of this hose?

The EVIL ENERGY hose delivers clear technical limits so you can match it to your system. It has a reliable working pressure range and a wide temperature tolerance for varied environments.

• Inner diameter: 3/8 inch (9.5 mm)
• Outer diameter: 0.63 inch (16 mm)
• Length: 10 feet (3.05 m)
• Working pressure: 250 PSI; burst pressure: 1000 PSI
• Temperature rating: -40°F to 257°F (-40°C to 125°C)
• Minimum bend radius: 85.5 mm

Which fluids and applications is the hose compatible with?

This hose is formulated to resist oils and certain chemicals used in automotive drivetrains and hydraulic systems. It is suitable as a connecting line for transmission coolers and can carry several common fluids, although always verify compatibility with specialty fluids before installation.

• Designed for transmission fluid and engine oil
• Accepts many hydraulic fluids and lubricants
• Can convey some gaseous media in non-pressurized or low-pressure uses
• Intended as the link between oil cooler and transmission or pump

How durable and flexible is the CPE construction?

CPE delivers a balance of toughness and pliability, resisting heat, oil soak, and environmental aging. The hose’s rated bend radius and temperature window make routing through engine bays and tight assemblies practical without sacrificing strength.

• CPE material resists oil absorption and heat-related degradation
• Wide operating temperature range for cold starts and hot running
• Minimum bend radius prevents kinking when routed correctly
• High burst pressure adds a safety margin under pressure spikes

How should I install and maintain this transmission cooler hose?

Proper installation and routine checks extend service life and reduce leak risks. Use appropriate clamps, avoid sharp bends, and inspect for abrasion or hardening at intervals.

• Cut squarely and deburr ends before attaching fittings or clamps
• Use compatible crimp or screw-type clamps rated for oil lines
• Avoid routing across sharp edges; protect with sleeves if needed
• Inspect periodically for soft spots, cracking, or swelling

Who this product is for: Mechanics, performance hobbyists, and fleet technicians who need a dependable replacement or custom-length connecting hose for transmission oil coolers will find this EVIL ENERGY hose useful. It fits installations that require a 3/8" ID, moderate pressure capacity, and resistance to heat and oils—common in aftermarket cooling setups, repair shops, and do-it-yourself vehicle maintenance projects. For specialized fluids or higher-pressure systems, confirm compatibility or consider hoses with different materials or higher ratings.
