• Intake Manifold Seal Rings

    These are the seals you have heard about, that can eliminate intake leaks, now at an affordable price, because of our investment in precision injection molds, and our expertise in molding exotic engineering materials.

    PEEK (polyetheretherketone) is a linear aromatic semi-crystalline 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.

    ENFIELD RACING is the only manufacturer in the world of injection molded seal rings for vintage V-Twin motorcycles in stock sizes.


    Follow standard installation procedures in addition to the following points.

    Do not over tighten; use approximately 1/2 of the normal torque on the nuts. Although not necessary, you may use a removable thread locking compound (blue) on the nuts only. Use a standard carburetor support. Leak test seal with 15 PSI pressure. Re-torque after several hours run time. NEED SEALS ? PEEK SEALS WE GOT SEALS !
