IsoTek™ Isolation Defender™ FS Gasket

Fire Safe

The Defender™ FS sealing/isolating gasket is designed to withstand the rigorous API stan-dard 6FB (Third Edition) test and therefore provides a solution for those who want to electrically isolate their flange while also requiring protection against the potential intro-duction of fire in and around the flange.

The objective of the test is to monitor the total leakage for the duration of the burn/cool-down cycle and during re-pressurization. Leakage was determined by the total water level drop through a visual sight gauge during the burn/cool-down cycles, by manually catching the water in a calibrated container during re-pressurization.

The results concluded that the Defender™ FS Gasket was able to maintain its fire safe characteristics throughout the entirety of the test. During the 30 minute burn and 30 minute cool down period, the measured leakage was 0 ml/min versus the allowable rate of 22.765 ml/min. The leakage rate during the re-pressurization cycle was 5 ml/min versus the allowable rate of 22.765 ml/min.

Based on years of technological experience with Kammpro® core design, the Defender™ FS sealing/isolating gasket not only meets but exceeds the pressure-containing capabilities in standard 6FB (Third Edition) as outlined by API.

General Features · Tested and Certified to API 6FB (Third Edition). · Two integral robust sealing elements for sealing and isolating in an engineered

IsoTek™ Isolation KitsSleeves & Washers

For complete isolation, sleeves and washers are needed with an IsoTek™ sealing and iso-lation gasket. To isolate connecting flanges and protect the gasket and flange from cor-rosion, Lamons provides sleeve and washer sets to complete the isolation system. The sleeves and washers prevent current from reaching the bolts/studs and nuts.Sleeve and washer sets are available in Single and Double washer sets.

API Standard 6FB Test Procedure

Note: The operating temperature for gaskets and flange isolation kits is based off the gasket retainer temperature. Seal element temperature does not dictate the minimum and maximum gas-ket operating temperature. Performance suitability and material compatibility shall be determined by the user. The Defender™ FS is an engineered fire safe gasket that has passed API 6FB fire test (Third Edition). No other claims regarding suitability/compatibil-ity for a particular application or performance in a fire are made.
