Dexter Oil Filler Plug 046-052-00, Rubber, Trailer Hub Oil Bath Service Part

The Dexter 046-052-00 is a rubber oil filler plug designed to seal the oil fill hole on Dexter trailer axle hub oil bath assemblies. This plug is sold as a service part only, meaning it is available as an individual replacement component rather than as part of a full hub kit -- ideal for trailer owners and service techs who need to replace a worn, cracked, or missing filler plug without purchasing an entire hub assembly.

The plug is made of rubber, which allows it to seat and seal securely in the fill hole to help keep the oil bath lubricant contained within the hub and keep contaminants out. Its compact size keeps it lightweight for easy handling and storage as a spare part. Because it is a genuine Dexter part identified by number 046-052-00, it is built to the same dimensions as the original equipment plug it replaces on applicable Dexter oil bath hub assemblies.
