0111802 Manifold intake seals. Plumber style

These Samwel plumber-style brass intake seals are the right choice for riders looking to keep their classic Big Twin or WLD running smoothly. Designed to sit between the manifold and the cylinder head, these brass inlet packing rings provide a durable, heat-resistant seal that modern rubber often cannot match in these vintage applications. They are an accurate replacement for OEM parts 27057-30 and 1118-30. Fitment includes 1934 to 1948 74-inch and 80-inch OHV models, 1936 to 1939 61-inch OHV models, and 1940 to 1946 45-inch WLD models. Keeping these seals fresh is the best way to avoid the lean-running conditions caused by manifold leaks, ensuring your engine stays cool and responsive.
