2 Way In Line Bulkhead #8 and #10 O-Ring

The 2 Way In Line Bulkhead #8 and #10 O-Ring from Vintage Air is a precision-engineered hydraulic and pneumatic adapter designed for high-performance cooling and fluid transfer systems. This streamlined bulkhead connector is built for automotive enthusiasts, custom fabricators, and technicians who demand reliable port connections in tight engine bay configurations. Whether you're installing air conditioning lines, transmission coolers, or fuel system components, this dual-port adapter simplifies complex plumbing layouts without sacrificing flow integrity or system pressure ratings.

Constructed from aluminum and finished with black anodized protection, this bulkhead fitting accommodates AN male O-ring connections on both the #8 (1/2-inch) and #10 (5/8-inch) ports, ensuring secure, leak-free seals in demanding applications. The aluminum construction keeps weight minimal while the anodized finish resists corrosion and extends service life in engine bay environments. The O-ring design eliminates the need for additional sealing tape or dope compounds, providing a straightforward press-fit installation that professional installers and experienced DIY builders prefer for repeatability and safety.

This adapter excels in custom air conditioning retrofits, street rods, race car builds, and modern engine swaps where factory plumbing routing doesn't align with aftermarket components. The compact, in-line profile fits behind grilles, under hoods, and in constrained engine compartments where traditional bulkhead plates would create installation conflicts. Technicians working with Vintage Air kits or standalone hydraulic systems will find this fitting compatible with standard AN hose crimping specifications, making it an essential piece for anyone serious about clean, professional fluid system integration.
