Style LS & LSI

TN_LSIDOWNLOAD DATA SHEET

Style LS spiral wound gaskets have been engineered to provide an alternative to sheet gaskets in Class 150 and Class 300 service.

The traditional spiral wound gasket has its steel windings protruding above the compression stop. (See Traditional vs. “LSI” and “LS” at the bottom left.) This requires a significant loading stress to compress the gasket to its optimum operating thickness.

The LS and LSI gaskets have only soft Flexicarb®, Thermiculite™ 835 or PTFE filler protruding above metal windings and guide ring. Therefore as the gasket is compressed the Flexicarb®, Thermiculite™ 835 or PTFE filler is readily compressed thus producing the sealing mechanism at an earlier stage as compared to the conventionally manufactured spiral wound gasket.
