9702-2 Manifold nuts, plumber style

These plumber-style manifold nuts from Colony are essential for maintaining the intake seal on vintage Harley-Davidson engines. Finished in a traditional parkerized coating, these nuts offer an authentic look for restorations where a chrome finish would be out of place. Sold as a pair, they fit 1934 to 1948 74" and 80" Side Valve models, 1936 to 1939 61" OHV Knuckleheads, and 1940 to 1946 45" WLD models. They are a direct replacement for OEM 27050-30, providing the correct fitment and thread pitch to secure your manifold nipples and prevent performance-robbing vacuum leaks.
