MILITARY SPECIFICATION

COPALTITE is the only sealant completely meeting U.S. Navy requirements for use on propulsion turbines (MIL-S-15204D).  The test consists of subjecting a seal to 950 degrees fahrenheit with superheated steam at 1200 psi for 96 hours and a cooling cycle every four hours.  NO leakage occurred and following the test the joint was readily broken.
