Overview

Introducing the EVIL ENERGY 6AN Male Inline Check Valve, a diaphragm-style inline valve engineered to support one-way flow in a compact, durable package. Built from high-strength aluminum and finished in black, it is designed to withstand the demands of modern engine bays and fluid systems.

Key specifications

  • Size: 6AN inlet/outlet with 9/16-18 UNF threads
  • Opening pressure: around 3 psi for initial flow
  • Maximum working pressure: up to 150 psi
  • Material: 6061-T6 aluminum alloy, black anodized for corrosion resistance
  • Valve action: diaphragm with a stainless steel spring to enable one-direction flow
  • Applications: suitable for fuel, oil, coolant, air, diesel, methanol, ethanol, and E85 in fuel systems

Real world use cases

In a performance fuel line, this valve helps prevent backflow during pump pauses or pressure spikes. In blends containing ethanol or methanol, the anodized body stays resilient against wear while the compact form fits in tight spaces. It is well suited for installations along braided lines, near fuel rails, or in compact engine bays where clearance is at a premium.

Benefits you may experience

  • Potential protection for upstream components by limiting reverse flow
  • Reduced siphoning risk when the system cycles on and off
  • Consistent flow direction in a variety of liquids and blends

Care and compatibility

Choose this valve when you need a lightweight, corrosion resistant inline check valve with diaphragm style action. Confirm compatibility with the specific fluids and temperatures you plan to use, especially with methanol or ethanol blends. Regular inspections of the diaphragm and spring are recommended.

Installation tips

  • Verify 6AN thread compatibility and ensure adequate clearance for installation
  • Secure with proper fittings to avoid leaks and ensure a clean mounting

FAQ
