EVIL ENERGY Transmission Oil Cooler Hose 5/16" x 10ft — 250 PSI CPE Oil-Resistant

EVIL ENERGY 5/16" transmission oil cooler hose is a 10-foot, CPE-lined fluid connection rated for 250 psi work pressure and built to resist heat, oil, and common automotive fluids.

This heavy-duty hose is engineered to link your transmission to an oil cooler reliably under demanding conditions. Constructed from chlorinated polyethylene (CPE), it balances flexibility and toughness across a wide temperature span, making it suitable for automotive and industrial fluid transfer where exposure to oil, lubricants, and hydraulic fluids is expected.

How does this hose handle high temperatures and oil exposure?

The CPE compound and internal construction are selected to tolerate heat and chemical exposure without rapid degradation. It stays flexible down to very low temperatures and resists hardening or swelling when in contact with transmission fluids and oils.

• Temperature range from -40°F to 257°F for broad climate performance
• CPE material offers oil and heat resistance compared with generic rubber
• Design minimizes swelling and softening from prolonged fluid contact

Is the hose strong enough for automotive transmission applications?

Yes—this line is rated for a 250 psi working pressure with a 1000 psi burst threshold, providing a wide safety margin for typical transmission cooler circuits. The specified minimum bend radius preserves flow and prevents kinking where space is limited.

• Rated working pressure: 250 psi, suitable for most cooler loop systems
• Burst pressure: 1000 psi for emergency strength
• Minimum bend radius: 72 mm to avoid restrictive bends and maintain flow

What are the hose dimensions and how will it fit my setup?

The hose has a 5/16" (8 mm) inner diameter and roughly 0.55" (14 mm) outer diameter, supplied as a continuous 10-foot length for cutting to the exact size you need. Its compact profile makes it compatible with standard clamps and fittings used in transmission cooler lines.

• Inner diameter: 5/16 inch (8 mm) for common cooler flow rates
• Outer diameter: approximately 0.55 inch (14 mm) for clamp/fitting compatibility
• Length: 10 feet, ready to trim for custom routing or repairs

Which fluids and applications is this hose suitable for?

Designed for transmission oil cooler connections, the hose also works with a variety of fluids such as hydraulic oils, lubricants, and certain gases where CPE compatibility is appropriate. It’s intended for use as a connecting line between transmission and cooler or similar fluid circuits, not as a primary high-temperature or pressurized main line outside rated specs.

• Compatible with transmission fluid, engine oil, hydraulic fluid, and lubricants
• Appropriate for oil cooler-to-transmission connections and auxiliary lines
• Not intended for use beyond the stated temperature and pressure ratings

Who is this for: Mechanics, performance enthusiasts, fleet maintenance teams, and DIY vehicle owners who need a reliable, oil-resistant hose for transmission cooler installations or repairs. If you require a flexible, compact line with proven oil and heat resistance, this EVIL ENERGY 5/16" CPE hose delivers a practical balance of durability, working pressure, and ease of routing for most cooler-loop applications.
