use with 2-1/8" Hex Manifold Nuts
These are the seals you have heard about, that can eliminate intake manifold leaks, and now at an affordable price.
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.
These seals can flex enough to fill in those extra minuet spaces that brass seals just cannot fill in. Well worth the extra expense to insure positive manifold seal - particularly when your 50 to 70 year old manifold may not quit be up to snuff.
INSTALLATION NOTES:
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.
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.
