Categories: , Tag:

CIERNE Sealing Gaskets has the excellent sealing and insulating design for all types’ flanges.The sealing elements encapsulated in the special designed groove, avoid the sealing element broken when the bolts torque are not equal.The material such Nitrile, EPDM, VITON and Telfon can be used as sealing elements, this increase the options for different working conditions.The KXTLG is available in both full-face (Type E) and ring style (Type F)configurations. Depending upon the sealing element selected, the CIERNE is rated for most all hydrocarbon and water service applications.Both retainer and sealing element’s temperature limit should be considered together while choose the material. Refer to chart for sealing gasket temperature range and material compatibilities
