EVIL ENERGY 6AN Male to 3/8" Barb Push-On Adapter, 2-Pack — 6061-T6 Aluminium, 1500 PSI Rated

EVIL ENERGY 6AN male to 3/8" barb push-on adapter is a two-piece aluminum fitting that converts an AN threaded line to a 3/8" rubber hose with a push-on barb connection.

This two-piece set from EVIL ENERGY is built for automotive and performance plumbing where a secure transition between a 6AN male thread and a 3/8" rubber hose is needed. Machined from 6061-T6 aluminum with a 37° AN sealing face, each adapter offers high-pressure capability and a broad operating temperature range, making it suitable for many fluid transfer tasks. These adapters are designed to be used with hose clamps for the most reliable seal.

How does this adapter fit into an AN plumbing system?

The adapter threads into a 6AN female port using the standard 9/16-18 UNF pitch while presenting a 3/8" barb for push-on hose. The AN side uses the 37° sealing geometry common to performance fittings, so it mates with matching AN female components.

• Thread specification: 6AN (9/16-18 UNF) male thread.
• Barb outer diameter sized for 3/8" ID rubber hose.
• 37° AN sealing face on the threaded end for compatible connections.
• Intended for use with rubber hose and hose clamps for best results.

What pressure and temperature can these push-on fittings handle?

These adapters are rated for high-pressure environments up to 1500 PSI when properly installed with compatible lines and clamps. The aluminum construction also tolerates a wide temperature span, keeping performance stable in both cold and hot operating conditions.

• Maximum rated pressure: 1500 PSI (when used as specified).
• Working temperature range: approximately -40°F to +250°F.
• 6061-T6 aluminum resists deformation across this range.
• Use appropriate hose and clamps to maintain pressure integrity.

Which hoses and installation methods work best with these adapters?

These fittings are expressly designed for rubber hose applications rather than hard-line or nylon tubing. For a leak-free installation, slide the hose fully onto the barb and secure it with a quality clamp; this prevents slippage and maintains the pressure rating.

• Only use with rubber hose (3/8" I.D.).
• Recommend stainless-steel or worm-gear hose clamps for secure sealing.
• Inspect hose for damage and ensure full barb engagement before clamping.
• Not intended for crimp-on or AN-style hose ends without modifications.

Who is this for?

This EVIL ENERGY 2-pack is ideal for mechanics, motorsport technicians, and DIY vehicle builders who need a compact, durable transition between a 6AN threaded port and a 3/8" rubber hose. If you work on fuel, coolant, vacuum, or oil return lines that use rubber hose and require the convenience of a push-on barb with AN compatibility, these lightweight aluminum adapters offer a practical and cost-effective solution. They’re best when used with proper hose clamps and within the stated pressure and temperature limits.
