How to fix a hole in a plastic oil tank

Updated April 17, 2017

Plastic is a very commonplace material used for just about everything. Because so much is made out of plastic, several companies have built their empire by providing various methods for repairing it. The most important element in plastic oil tank repair is to know exactly what kind of plastic your oil tank is made of. This allows you to purchase the proper patching materials. There are multiple ways of repairing your plastic oil tank, which method you select depends mostly on how much you care about appearance versus ease of use.

Repair your plastic oil tank with a plastic repair kit. Plastic repair kits are available at any hardware store and are relatively inexpensive. These kits contain epoxy, fibreglass cloth, application brush and sandpaper. Simply sand down the crack or hole, cover it with the fibreglass cloth, prepare the epoxy and brush it over the fibreglass to create a patch. These patches appear rough at first, but you can sand them down for a more aesthetically pleasing finish once the epoxy has set. Additionally, you can paint the patch to match the rest of the tank. Plastic repair kits are great if you're not too bothered with a rough finish.

Repair your plastic oil tank with a plastic sealing tape. Sealing tapes are available at any hardware store and are great for an easy fix for smaller cracks and holes. Sealing tapes adhere well to any plastic type and can maintain seal in temperatures as low as -4.44 degrees C to 82.2 degrees Celsius. Simply apply the sealing tape over the small hole or crack to solve your problem. Note: sealing tape gets the job done, but you may have to replace it from time to time. Sealing tape is perfect for a person that's looking for a quick and easy fix to a small problem.

Repair your plastic oil tank with a speed tip plastic welder. Speed tip welding is a technique that heats up a plastic rod while pushing a soft bead of plastic out of the tip, similar to soldering. Although speed tip welding offers the most precise plastic repair, it is also the most challenging and expensive plastic repair method. Speed tip welding is also the best method for repairing a crack or a hole in a hard to repair area such as a corner. Speed tip welding is perfect for hobbyists and professionals who really value the aesthetic appearance of the repair work.
