The LS gasket offers the same high integrity seal associated
with the spiral wound gasket however, the LS and LSI has been
designed in such a way that compression and sealing requirements
are achieved under very low seating stresses. These gaskets
are intended for use on class 150 and 300 applications,
where customers traditionally do not use spiral wound gaskets
due to concerns about exceeding allowable design stresses.
The traditional spiral wound gasket has its steel windings protruding
above the compression stop; this requires a significant loading
stress to compress the gasket to its optimum operating thickness.
The LS and LSI gaskets have only soft Flexicarb® or PTFE filler
protruding above metal windings and guide ring; therefore as the
gasket is compressed, the Flexicarb® or PTFE filler is readily compressed
thus producing the sealing mechanism at an earlier stage
as compared to the conventionally manufactured spiral wound
gasket.
The “LSI” gasket retains more of its initial stress or tightness,
even when subjected to high temperatures, unlike PTFE sheet
gaskets.
