SPECIAL GASKETS
Gaskets of special design can be
engineered and fabricated using
the same basic fundamentals of
Flexitallic Spiral Wound Gasket
design and construction to cover
a wide range of applications in
installations for which there are
no industry-wide standards.
Special gaskets have been
designed for valves, pumps,
compressors, turbines, boilers,
heat exchangers, etc. Consult with
Flexitallic engineers as early in the
design stage as possible.
