Product Description
Upgrade and simplify your hydraulic steering plumbing with the PSC SF04 AN Adapter Fitting 6AN x 5/8-18 Inverted Flare. This precision-machined adapter allows seamless conversion from a traditional SAE inverted flare steering port to a modern -6AN hydraulic hose connection. Built by PSC Steering Components for high-performance steering systems, this fitting is commonly used when converting factory steering gearboxes and pumps to AN-style hoses for improved reliability, serviceability, and performance. The SF04 adapter is most commonly used to adapt the low-pressure port on 1979 and older GM Saginaw steering gearboxes to -6AN fittings. Fabricated from durable steel with a corrosion-resistant zinc finish, this straight adapter provides a secure, leak-free connection for hydraulic steering systems used in off-road trucks, Jeeps, rock crawlers, and performance builds.
