Fitting

The Holley 26-29 fitting adapter is a straight adapter designed to connect male and female hose connections in fuel systems, cooling systems, and hydraulic applications. This brass fitting serves as a critical junction point in fluid transfer systems where two different port sizes or thread types must mate seamlessly. Whether you're building a custom fuel line configuration, upgrading cooling lines, or assembling a hydraulic setup, this adapter eliminates the need for custom fabrication or workarounds.

Constructed from durable brass in natural finish, the Holley 26-29 features a 9/16-24 inch male thread on one end and a 3/8 inch hose barb on the other, providing a robust mechanical connection that resists corrosion and withstands moderate pressure cycles. The straight design ensures minimal flow turbulence and allows for tight routing in compact engine bays or chassis configurations. Brass material offers excellent thermal conductivity and compatibility with most automotive fluids, while the hose barb design accommodates standard hose sizes with secure crimping or clamp-based attachment.

This fitting is ideal for fabricators, hot rodders, and performance enthusiasts who require flexible routing options and reliable adapters for fuel, coolant, and brake line systems. The compact 3.5 x 1.05 x 5 inch footprint allows installation in tight spaces without interfering with engine components or chassis elements. Installation is straightforward: thread the male end into the receiving port with appropriate thread sealant and secure the hose barb with a stainless steel clamp, ensuring a leak-free connection that meets both street and competition standards.
