When using brass fittings on an aluminum body, the fittings can become increasingly difficult to remove due to galvanic corrosion and thread galling. To prevent this, always isolate the metals by using a dielectric fitting—such as a plastic adapter—to separate the brass from the aluminum threads. Alternatively, select transition fittings specifically engineered for brass-to-aluminum connections, as these are often plated or designed to prevent direct metal contact. Another option is to apply a high-quality anti-seize compound before assembly; this lubricant forms a protective barrier, helping to reduce corrosion and ease future removal of the fittings. Taking these steps will ensure the longevity and serviceability of your manifold block connections.
