Merrill Yard Hydrant Plunger Installation Grease

This Is A Silicone Lubricant For The Rubber Plunger In A Yard Hydrant. It Will Not Swell Or Destroy The Plunger like other lubricants can. It is a small amount but more than needed for a plunger. It is put on a new plunger to make it easier to slide the plunger into the brass base where it makes a tight seal.
