Anaerobic Sealants
Flange Sealing
Hernon Gasket Replacer anaerobic adhesives are
single component, 100% active, ready-to-use gel-like materials
that cure at room temperature. Gasket Replacer products cure
only after confinement (the nature of anaerobic adhesives) between
mating surfaces. They remain wet during assembly. After curing
and filling all imperfections, Hernon Gasket Replacer products
form a thin, tough, resilient, solvent, and temperature resistant
seal.
Gasket Replacer adhesives are superior to other
gasketing methods. They contain no solvents and do not shrink,
stretch, split, rot, distort, wear-out, or relax. Joints never
need re-torquing. 
Because the gasket is formed when parts are made-up,
that is, bolted together, the plastic shim formed is truly a
"custom" gasket seal. Gel not forced out cures to a
shim as an exacting match of the surface irregularities. The
shim mirrors and fills all the voids, nicks and scratches present
in even the best machines flanges.
These compounds also find utility in improving
the performance of mechanical clamping of flanges. Flange loading
is more uniformly distributed when rigid metal faces are in intimate
contact, as opposed to clamping with a cork or rubber gasket
sandwiched between the parts. Greater load distribution is synonymous
with greater seal integrity over time and vibration.
