EVIL ENERGY 5/16" Transmission Oil Cooler Hose 5FT 250PSI

EVIL ENERGY 5/16" Transmission Oil Cooler Hose is a 5-foot, SAE J1532-compliant CPE hose designed to connect transmission and oil coolers safely at up to 250 psi.

This hose is built for vehicles and equipment that demand an oil- and heat-resistant link between the transmission and external coolers. Constructed from chlorinated polyethylene (CPE), it balances flexibility with chemical resistance and holds a working pressure of 250 psi. The 5-foot length and 5/16" inner diameter suit many retrofit, replacement, and custom installations where a reliable fluid path is required.

How does this hose stand up to heat, oil, and pressure?

The CPE compound resists oils, fuels, and many transmission fluids while remaining flexible across a broad temperature band. It carries a 250 psi working pressure with a 1000 psi burst margin for added safety. Temperature performance ranges from -40°F to 257°F so it can handle hot engine-bay environments and colder climates without stiffening or cracking.

• Material: durable chlorinated polyethylene (CPE) for oil and heat resistance
• Working pressure: 250 psi; burst pressure: 1000 psi
• Temperature range: -40°F to 257°F for wide climate reliability

Will the dimensions and flexibility suit my vehicle or project?

This hose has an inner diameter of 5/16" (8 mm) and an overall outside diameter of 0.55" (14 mm), providing a compact profile ideal for tight routing near the engine and cooler lines. The 5-foot length offers flexibility for many common installations, and the minimum bend radius of 72 mm helps prevent kinking when routed around brackets and components.

• Inner diameter (ID): 5/16" (8 mm) for compact fluid paths
• Outer diameter (OD): 0.55" (14 mm) for snug routing in constrained spaces
• Length: 5 feet—suitable for replacements and custom runs
• Minimum bend radius: 72 mm to avoid stress and kinks

Which fluids and applications are appropriate for this hose?

The hose is compatible with transmission fluids, engine oils, hydraulic fluids, lubricants, and some gases, making it versatile for cooler lines and related fluid transfer. It’s designed specifically for the connection between oil coolers and transmissions, offering a safe, oil-resistant pathway that reduces leaks and deterioration compared with general-purpose tubing.

• Compatible media: transmission fluid, oil, hydraulic fluid, lubricant, some gases
• Typical use: connecting transmission to oil cooler in automotive or mobile equipment
• Benefit: heat and oil resistance for longer service life around engine bays

How do I install and maintain this transmission cooler hose?

Installation is straightforward—cut to length if needed, secure with appropriate clamps rated for transmission service, and avoid sharp bends or abrasive contact points. Inspect clamps and hose ends periodically for wear and replace immediately if you see swelling, deep abrasion, or leaks. Proper routing and clamp selection extend service life and maintain reliable pressure containment.

• Cut cleanly and use compatible hose clamps or fittings
• Avoid contact with hot exhaust or sharp metal edges without protection
• Regular visual checks for wear, swelling, or leaks are recommended

Who is this for: EVIL ENERGY’s 5/16" Transmission Oil Cooler Hose is aimed at mechanics, DIY enthusiasts, fleet technicians, and restoration projects that need a compact, oil-resistant hose for transmission cooler connections. It’s suited to applications requiring SAE J1532-style performance, reliable temperature tolerance, and a 5-foot length for retrofit and custom routing tasks.
