KLINGERSIL® C-7400 Isolation Gaskets
Some applications in plants call out for isolation kits to maintain the integrity and reliability of a pipeline and piping system. Isolation kits are designed to work in conjunction with flanges, gaskets, and/or bolt sleeves and washers by eliminating metal-to-metal contact and halting static electric currents. At times they are relied upon for critical applications in severe temperatures and conditions.
Industry’s first choice are phenolic gaskets. They are often supplied in kits, but they are hard and typically take a lot of load to seal. And lack of load is the number one reason for gasket failure.
KLINGERSIL C-7400 is an EPDM and aramid fiber gasket material that can satisfy both sealing and electric requirements. Gaskets made from this material provide an effective seal with its low minimum sealing stress, and its non-conductive properties provide electrical isolation of the flanges.
KLINGERSIL C-7400 can be used as a non-conductive isolator and as a sealing material in bolted joints replacing phenolic gaskets. KLINGERSIL C-7400 has the highest dielectric strength when compared to many of the other Thermoseal products. The dielectric strength of KLINGERSIL C-7400 is 22 kv/mm.
