Lovejoy 68514449969 Universal Joint Boot

Product Description

The LOVEJOY 68514449969 is a universal joint boot designed to protect U-joint assemblies from contamination, moisture, and debris. It features a 7/16-inch inside diameter and a 1-1/2-inch outside diameter, with an overall length (OAL) of 1.52 inches and a bore depth of 7/8 inch. Rated for up to 1,176 inch-pounds of torque, this boot provides a reliable seal around the joint interface. It is installed by mechanical and drive-line technicians working on rotating-shaft assemblies where maintaining lubrication and excluding contaminants are essential to service life.

This universal joint boot is suited for drive-shaft and rotating-shaft applications where a protective flexible boot is required over the U-joint. Its compact profile and defined bore geometry make it a direct-fit component in assemblies requiring the specified inside and outside diameters. Each package contains two boots, making it practical for twin-joint service or to keep a spare on hand. The part is appropriate for both initial installation and replacement service in light mechanical and drive-line applications.

Inspect the joint and surrounding components for wear or damage before installing the replacement boot. Follow all applicable manufacturer guidelines and workplace safety procedures during disassembly and reassembly.
