D/Sump Fit. 12an Plug

The Peterson Fluid D/Sump Fit 12 AN Plug (part number 08-0505) is a precision-engineered hydraulic fitting designed for high-flow fluid systems where reliable sealing and quick draining are essential. This 12 AN aluminum plug features an O-ring seal and Allen head design, making it ideal for racing, marine, aerospace, and industrial applications where system integrity under pressure is non-negotiable.

Constructed from aluminum with clear anodized finish, this 12 AN fitting resists corrosion while maintaining light weight—critical in high-performance environments where every pound matters. The O-ring seal design ensures leak-free operation under vibration and thermal cycling, while the Allen head socket allows secure installation and removal with standard hex tools. The compact profile (2.7 x 0.85 x 2.9 inches, 0.15 lbs) fits tight engine compartments and system layouts without compromising accessibility for maintenance.

Technicians and builders rely on Peterson Fluid fittings for applications requiring SAE/AN standard compliance—particularly in fuel systems, oil circuits, coolant loops, and transmission coolers where pressure ratings and flow capacity are matched to the 12 AN specification. The plug design enables rapid system draining during maintenance or component replacement, reducing downtime and fluid waste. This is the engineered choice for serious performance platforms where compatibility with standard AN hose and line systems is essential.

Peterson Fluid is a trusted OEM supplier for racing teams, marine builders, and industrial facilities, known for precision tolerances and consistent quality. Each plug ships individually, allowing selective replacement or system expansion without bulk purchasing.
