PEEK Intake Manifold Seals coming soon for Harley J and JD's.
Soon we'll have PEEK Intake / Inlet manifold seals in stock for both 61" and 74" Harley JD's. We are also planning to make them to cover 1930 to 1954 Harley Davidsons. Our JD part numbers will be 1118-15P and 1118-23P.
These are the seals you have heard about, that can eliminate intake leaks. PEEK (polyetheretherketone) is a thermoplastic developed in the late 1960’s. It is widely regarded as the highest performance material capable of being processed on conventional thermoplastic equipment.
PEEK has a melting point of 650°F (343°C) with a continuous use temperature of 500°F. It has outstanding creep resistance for an engineering thermoplastic material and can sustain large stresses over a useful service life without significant time induced extrusion.
