EVIL ENERGY 6AN PTFE Stainless-Steel Braided Fuel & Transmission Hose Kit 70" – AN6, High-Temp 3000 PSI

EVIL ENERGY 6AN PTFE 70" hose kit is a stainless-steel braided, high-temperature fuel and transmission fluid line engineered for demanding automotive cooler and fuel applications.

This 70-inch AN6 PTFE hose assembly combines a smooth PTFE inner liner with a stainless-steel braid and AN6 fittings to deliver high pressure resistance, chemical compatibility, and reliable flow for transmission coolers, aftermarket oil coolers and fuel systems. It’s built to operate across a wide temperature range and includes common connector options so it fits many popular automatic transmissions and performance drivetrains.

Which vehicles and transmissions is this hose kit compatible with?

The EVIL ENERGY 6AN kit supports a broad range of transmissions commonly used in performance and replacement applications. It lists compatibility with GM and Ford automatic transmissions as well as several popular legacy and performance units.

• Directly referenced fits: TH350, TH400, 4L60E, 4L80E, 700R4, 200-4R, TR6060, Ford AOD, 4R100, 4R70W, C5 Corvette lines.
• Universal AN6 sizing lets you adapt to many aftermarket coolers and fittings with the correct adapters.
• Measure existing line lengths and thread types to confirm proper fit before installation.

How does the hose perform under heat and pressure?

This PTFE-lined assembly is designed for demanding thermal and pressure environments. The inner PTFE liner resists deformation and chemical breakdown while the stainless braid adds burst and abrasion protection.

• Working temperature range: -76°F to 500°F (-60°C to 260°C).
• Rated working pressure: up to 3000 PSI; burst pressure up to 10,000 PSI.
• Stainless braid resists chafing and supports long service life in engine bays and under-hood routing.

What are the fittings, dimensions, and installation notes?

The hose ID and OD are specified for AN6/PTFE performance and the kit includes common connector threads for easier integration. Because PTFE hose is relatively stiff compared to rubber, routing and professional installation are recommended to avoid kinks or sharp bends.

• Hose size: PTFE 6AN inner diameter 5/16" (0.31 in), outer diameter 0.45 in, total length 5.8 ft (70 in).
• Connector specifications included: 9/16-18 UNF, 3/8-18 NPT, and 1/4-18 NPT thread options.
• Note: PTFE construction resists crushing but cannot be folded in half; allow smooth bends and use proper clamps and adapters.

Why choose a stainless-braided PTFE line over standard rubber hose?

Stainless-braided PTFE lines combine chemical compatibility and pressure tolerance with reduced permeability compared with many rubber hoses. That makes them preferable for performance, racing, and retrofit cooler lines where heat and exposure to additives can shorten standard tubing life.

• PTFE inner liner resists fuels, transmission fluid and many additives without swelling or softening.
• Stainless outer braid provides mechanical protection and improved burst resistance under higher pressures.
• AN6 sizing is standard in performance plumbing, simplifying integration with aftermarket fittings and coolers.

Who is this for? The EVIL ENERGY 6AN PTFE 70" hose kit is aimed at car builders, performance hobbyists, and technicians upgrading transmission or oil cooler plumbing on muscle cars, late-model swaps and race vehicles. If you need a longer, high-temperature hose run with AN6 fittings for a TH350/TH400 or modern automatic like the 4L60E/4L80E and similar units, this kit offers a durable, chemical-resistant solution. Confirm thread types and measure your routing path before ordering; professional installation is recommended to ensure correct fitment and safe bend radii.
