This kit is a PATCH, it is NOT a replacement barrel This is a D.I.Y. repair kit for Harbor Freight Single or Double Barrel Tumblers and Loretone 1.5 , 3-1.5B, 3A or 33B Tumblers. This kit restores the rubber barrel ends that typically wear first. The rock tumbler barrel takes a lot of abuse during repeated tumbling operations, while the drum side wall is thick and sturdy, unfortunately the bottom and top sealing cover are only about an 1/8 of an inch thick. With the action of the abrasive grit and the wear from the lid tightening screw, severe damage is done to the barrel. Eventually the bottom or top cover will wear through and cause fluid to leak out, effectively ending the life of the barrel. New barrels run as high as $25.00, this kit will restore the life of the barrel for a fraction of the cost of a new barrel. This sale contains two patches that are not made from the same soft, weak and rapidly deteriorating rubber of OEM, rather they are made from the same material that manufactures make shoe soles from. This repair kit will ensure long tumbling life not only from a worn out barrel, but can also be used to fortify existing barrels to keep them in like new condition for many years to come. This kit is sold as a two pack repair solution. This kit will repair both sides of a single tumbler barrel, the top and bottom. Each kit contains a specially prepared patch (pic #6), which will fit 4 1/2 inch diameter tumbler barrels and lid gaskets, a single use adhesive (pic #7) to mount over the existing end, and repair instructions. This sale is for two kits, which contains 2 patches and two adhesives, no tumbler, no barrel, no lid, no rocks included. Please ask questions prior to purchase, no returns on used items.
