A seal for a gas turbine engine includes a top, a bottom, a left side, a right side, a back and a front. The back is parallel to the front and the left side is parallel to the right side such that a non-square shape is formed by the intersection of the back, the left side, the front and the right side. The top includes a first vane mating surface and the bottom includes a second vane mating surface.

Universal seal

According to the present disclosure, a method for securing a threaded fastener in a threaded hole includes directly applying a locking compound to at least a portion of threads to be mated on either the threaded fastener or the threaded hole. The locking compound includes a substantially pure, non-chromated aluminum pigmented compound suspended in a water-based inorganic binder with temperature resistance in excess of 900 degrees Fahrenheit (about 482 degrees Celsius). The threaded fastener is threaded into the threaded hole after applying the locking compound on the threads to be mated.

High temperature thread locking compound

A seal for a gas turbine engine is shown. The engine may have a first vane for imparting a first twist to air passing thereby and/or a second vane for imparting a second, different twist to air passing thereby, each of the first and second vanes having a mounting area for mounting the seal thereto. The seal includes a top, a bottom, a left side, a right side a back, and a front. The back is parallel to the front and the left side is parallel to the right side such that a non-square shape is formed by the intersection of the back, the left side, the front and the right side so that the seal may mate with the mounting area of the first vane and, if the seal is inverted, may mate with the mounting area of the second vane.

An assembly includes a threaded hole, a threaded fastener, and a locking compound. The threaded fastener is positioned in the threaded hole with a portion of fastener threads mated with a corresponding portion of hole threads. The locking compound is between the mated fastener threads and hole threads. The locking compound includes an aluminum pigmented compound suspended in a water-based inorganic binder.
