Podavelle 6AN Male Flare to M16x1.5 O Ring Seal Power

Podavelle's AN6 (9/16-18 UNF) to M16x1.5 O‑ring adapter is a durable, high‑pressure aluminum fitting made to convert AN6 hose ends to newer GM power steering boxes that accept M16x1.5 o‑ring style connections.

Use these two black anodized fittings when you need a reliable, corrosion‑resistant transition between aftermarket AN6 lines and modern GM o‑ring steering boxes. Machined from 6061‑T6 aluminum, they balance lightweight construction with the strength required for high‑pressure power steering systems and are compatible with gasoline and alcohol based fluids. Each kit contains two matching adapters finished in hard anodize to resist wear, protect threads, and maintain a tidy under‑hood appearance.

How do these adapters connect AN6 hoses to modern GM steering boxes?

The adapter has an AN6 (9/16‑18 UNF) male flare thread on one end and an M16x1.5 o‑ring style sealing face on the other, allowing direct mating to GM o‑ring ports. Installation requires the mating o‑ring and proper torque to ensure a leak‑free seal under pressure.

• AN6 male flare: 9/16‑18 UNF thread for standard AN hose fittings
• M16x1.5 o‑ring face: designed for newer GM power steering boxes
• O‑ring seal: uses an o‑ring at the M16 end for pressure sealing
• Sold as a pack of two for inlet and outlet or spares

Are these fittings strong enough for high‑pressure power steering systems?

Yes — machined from 6061‑T6 aircraft‑grade aluminum and protected by an anodized coating, these adapters are intended for high‑pressure hydraulic service such as power steering. They offer a high strength‑to‑weight ratio and corrosion resistance commonly required in automotive under‑hood environments.

• 6061‑T6 material provides structural durability while remaining lightweight
• Hard anodized finish increases surface hardness and resists corrosion
• Suitable for continuous high‑pressure fluid flow in steering systems
• Compatible with gasoline and alcohol based fluids to prevent degradation

What should I check before buying and installing these adapters?

Confirm your steering box uses an M16x1.5 o‑ring sealing face and that your hoses or fittings are AN6 (9/16‑18 UNF). Because correct installation and torque are essential for safety and leak prevention, professional installation is recommended if you are not experienced with hydraulic fittings.

• Verify steering box port specification: M16x1.5 o‑ring type
• Confirm hose/fitting side is AN6 (9/16‑18 UNF)
• Inspect and replace o‑rings as needed before assembly
• Use proper torque and thread seal practices recommended for steering systems

Who is this for? These Podavelle adapters are intended for automotive enthusiasts, mechanics, and fabricators who are upgrading or repairing power steering systems and need a dependable AN6‑to‑M16x1.5 o‑ring conversion. They suit projects where weight savings and corrosion resistance matter, such as custom hose assemblies, retrofit kits, or when integrating aftermarket AN lines with newer GM steering boxes. Note: no installation instructions are supplied and professional installation is highly recommended to ensure proper sealing and system safety.
