摘要： A pre-installation liquid level gauge assembly is provided which comprises a fitting with a threaded outer surface and a thread protector friction fit over the threaded outer surface. The thread protector comprises a sleeve portion and a shoulder portion extending radially inwardly to protect the end of the fitting and prevent the sleeve portion from sliding up the fitting to expose some of the lower threads. The shoulder portion defines a hole that is larger than the outer diameter of the passage in the fitting so that the thread protector does not interfere with the insertion of an extension piece into the passage in the fitting. The thread protector includes a tab and a scored line extending from the tab to the edge of the hole defined in the shoulder portion such that the tab can be pulled to totally split the thread protector to allow ready removal of the thread protector from the fitting.
