Abstract

An adaptor for generally permanent coupling of a lubricant line to a lubricant fitting. The fitting has a base, a neck, a head, a lubricant passage, and a valve member biased toward a closed position. The adaptor comprises a body having a hole extending therethrough and an insert in the hole having a circular head and a thin-walled cylindrical extension extending from the head slidable in the hole. The extension defines a socket for receiving the head of the fitting on application of the body and insert to the fitting. The extension is radially inwardly deformable into interlocking engagement with the fitting. The head of the insert has a pin extending therefrom within the socket in the direction toward an inner end of the hole. The head includes a passage for flow of lubricant therethrough. The body is formed for connection thereto of a lubricant line and has a wedging formation in the hole for radially deforming the extension into tight sealing engagement with the head of the fitting on forcible movement of the insert in the body toward the inner end thereof. The pin enters the head of the fitting with movement of the insert and engages a valve member in the fitting to move it to an open position by engagement of the pin with the valve member for flow of lubricant through the fitting.
