Featuring a high-grade Teflon (PTFE) construction, this gasket is designed to provide a superior seal with exceptional chemical and heat resistance. The Teflon coating provides a low-friction surface that allows for the natural thermal expansion and \"scrubbing\" movement between the cylinder head and the block without compromising the gasket's structural integrity.\u003c\/p\u003e\n\n\u003cp\u003eBuilt to endure the intense thermal cycles of air-cooled V-Twin engines, this gasket effectively conforms to microscopic surface irregularities to prevent combustion leaks and oil migration. As a direct-fit replacement, it offers excellent torque retention and durability, making it an ideal choice for riders and builders performing top-end rebuilds or maintenance on classic Evolution and 1200 Sportster powertrains.\u003c\/p\u003e","brand":"Harley-Davidson","offers":[{"title":"Default Title","offer_id":53027659186400,"sku":"NFHGBTSBTEF","price":3.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/8451\/9648\/files\/BigTwin_1200ccSportsterHeadGasket_HGBTSBTEF.png?v=1781093989","url":"https:\/\/nightforgeparts.com\/products\/1985-1998-harley-davidson-big-twin-1200cc-sportster-head-gasket-teflon","provider":"Night Forge Parts","version":"1.0","type":"link"}
