EVIL ENERGY 5/16" Transmission Oil Cooler Hose — 10 ft CPE, 250 PSI Working Pressure, Heat‑Resistant

EVIL ENERGY 5/16" Transmission Oil Cooler Hose is a 10-foot CPE line rated for 250 PSI working pressure, built to connect your transmission to an oil cooler with heat and oil resistance.

This hose is engineered for vehicles and machinery that need a durable, flexible connection between a transmission and an external oil cooler. With an inner diameter of 5/16" (8 mm), 0.55" outer diameter, and a 10-foot length, the hose combines chemical compatibility and a wide operating temperature range so it withstands harsh under‑hood conditions. It’s designed to carry transmission fluid, oil, hydraulic fluid, lubricants, and compatible gases while resisting heat, oil, and abrasion.

How does this hose handle high temperatures and oil exposure?

The hose uses CPE (chlorinated polyethylene) construction, chosen for its resistance to heat and petroleum-based fluids. Its rated temperature range from -40°F to 257°F keeps flexibility in cold starts and stability at elevated under‑hood temperatures without rapid degradation.

• Material: CPE for oil and heat resistance
• Operating range: -40°F to 257°F
• Resists swelling and softening from transmission fluids

What pressure and strength can I expect during use?

Designed for medium-pressure cooling lines, the hose carries a 250 PSI working pressure with a 1000 PSI burst threshold for a robust safety margin under temporary pressure spikes. Its minimum bend radius and construction help prevent kinks and burst risk when routed through tight engine bays.

• Working pressure: 250 PSI for typical transmission cooler circuits
• Burst pressure: 1000 PSI providing substantial safety margin
• Minimum bend radius: 72 mm to avoid kinking

Will this hose fit my vehicle and how easy is it to install?

The hose’s 5/16" ID is a common size for many aftermarket and OEM transmission cooler lines; its 10-foot length provides extra material for custom routing or cutting to fit. Installation requires appropriate clamps or fittings rated for the same pressure and fluid compatibility; cut to length and secure with high-quality hose clamps or swage fittings for leak-free performance.

• Inner diameter: 5/16" (8 mm) — common transmission cooler size
• Length: 10 feet, easily trimmed for custom installations
• Use compatible clamps/fittings rated for 250 PSI and transmission fluid

What fluids can flow through this hose safely?

The CPE compound offers compatibility with a range of automotive and hydraulic fluids, including transmission fluid, engine oil, hydraulic oils, and many lubricants. Avoid incompatible aggressive solvents outside manufacturer recommendations and confirm compatibility if you plan to run nonstandard fluids or fuels.

• Compatible: transmission fluid, oil, hydraulic fluid, lubricants
• Not intended for prolonged exposure to strong solvents unless confirmed
• Check fittings and clamps for chemical compatibility too

Who is this hose for? Mechanics, DIY enthusiasts, custom builders, and fleet technicians who need a dependable, oil-resistant transmission-to-cooler connection will benefit from this EVIL ENERGY hose. It’s suited for repairs, retrofits, or custom cooling loop installations where flexibility, temperature resilience, and a known pressure rating are required. Always match hose size, material compatibility, and fittings to your specific vehicle and application before installation.
