Abstract
An initiation fitting (10) includes a sleeve member (12) having a first end to which a fuse (18) or other initiator is connected and a second end to which an initiating charge (38) is connected for initiating a connected device such as a rocket motor and to hinder the venting of gases from the device through the fitting (10). The sleeve member (10) includes an internal passage (14) extending therethrough and a malleable internal flange (48) which protrudes into the internal passage (14). The internal flange (48) is dimensioned and configured so that when the initiating charge (38) detonates, the internal flange (48) collapses into the internal passage (14) to hinder the flow therethrough of explosive gases from the second end of the fitting.
