#500 PLAIN, CORRUGATED, ALL-METAL GASKETS
For low-pressure applications which demand a thin-line, contact-type seal
due to weight or space limitations. Metal thicknesses range from .010"
to .031", depending upon kind of metal and corrugation pitch. Thickness
under .010" may rupture when corrugated. Minimum of 3 concentric corrugations
are suggested for each gasket face, although there are successful applications
using only one. A slight flat within the inner corrugation and another beyond
the outer corrugation serve to stiffen the gasket and are recommended when
space permits. Optimum performance requires corrugations on both gasket
faces instead of being embossed on only one face. Corrugation pitch for
other #500 applications may run from .045" to 1/4", while overall
gasket thicknesses will vary from 40% to 50% of corrugation pitch. Temperature
ranges depend on metal used. Pressure limit, 500 psi.
#505 CORRUGATED GASKET CORD FILLED
This is the #500 with cord cemented into the corrugations. Metal thickness
is about .019" or .020". Corrugation pitch is 5/32", 3/16"
or 1/4", according to gasket width or application. Approximate overall
gasket thickness is 65% to 70% of pitch. #505 is a highly effective replacement
for millboard gaskets on large-diameter flanges which handle flue and combustion
gases at temperatures up to 1150 deg F (depending on the metal) under light
pressures. Frequent breakage is a recognized problem in the handling of
millboard gaskets. #505 gaskets withstand pressures to 600psi. They are
not suited for vacuum or oil service.
