3/8 in. Bulb Style Hose Barb to -6AN Adapter Fitting for Power Steering Reservoir Return

• Connects -6AN hose to a GM power steering port

• 3/8" bulb-style barb, built for reservoir return line use

• Confirm O-ring vs. inverted flare port sealing style before ordering

• Fits GM muscle car, truck, hot rod, and LS swap applications

This 3/8" bulb-style hose barb to -6AN adapter connects -6AN hose plumbing to a matching GM power steering reservoir return port. The fitting is built for custom steering hose assemblies, steering box or rack conversions, and LS swap power steering plumbing that uses the matching O-ring or inverted flare connection.

This fitting is designed for the reservoir return (low-pressure) side of the power steering system — confirm your application before using this on a pressure-side connection, since the bulb-style barb design is intended for return-line use. Use it when adapting a GM steering box, rack, or power steering pump to -6AN hose. Confirm port thread, sealing style, hose pressure rating, steering fluid compatibility, and fitting clearance before installation.

Applications
Connects -6AN hose plumbing to a GM power steering reservoir return port (O-ring or inverted flare connection). Common on GM muscle car, truck, hot rod, and LS swap power steering systems.

Port Sealing Style
Confirm whether your steering box, rack, or pump uses O-ring or inverted flare sealing — this affects which port thread matches this fitting.

Installation
Verify port thread, sealing style, hose pressure rating, steering fluid compatibility, and fitting clearance before installation.

Is this fitting for the pressure side or return side of my power steering system?
This fitting is designed for the reservoir return (low-pressure) side of the power steering system. It is not intended for high-pressure line connections.

How do I know if my steering box uses O-ring or inverted flare sealing?
Check the port style on your steering box, rack, or pump before ordering. O-ring and inverted-flare connections use different sealing methods and are not interchangeable simply because the thread size appears similar.

What vehicles is this commonly used on?
It's commonly used in GM muscle car, truck, hot rod, and LS-swap power steering systems using the matching port configuration and -6AN hose plumbing. Always verify the actual steering component's port before ordering.
