Holes can be of several types. Some may be accidental, while others may be expected or done purposefully. Whatever the variety of a hole is, it must be covered to avoid leakages.
Indeed, there are cases in which a hole is designed to be exposed, possibly for ventilation. But in most situations, they must be hidden or masked so that the object’s surface retains a proper structure.To cover holes, you need to use a hole plug. Even though the holes can vary widely in shape and size, you can easily find a rubber hole plug that perfectly fits and conceals the hole.
If you want a smoother finish, make sure the rubber hole plug has the same color as that of the material, and if not, you can always paint over it.
The top of the plug has to be flat and not risen or projected upwards. If you run your hand along the material’s surface, the hole shouldn’t be detected.
If you’re not sure about the type of rubber hole plug you should get, here is a list of some plugs you can use depending on the required usage, size, and thickness.
Liquid-tight plugs: If you don’t want any liquid leakage from the holes, you should go for liquid-tight rubber hole plugs.
They are rain-proof, oil-proof, and work well even when submerged.
Finishing dome plugs – These plugs are available in many sizes and colors. They are mainly used to conceal panel holes that have fulfilled their purpose.
Threaded plugs – The threaded plugs can be used as temporary plugs so that they may add threaded tools later down the road. People may also use them to cover metric threaded holes.
Sheet metal plugs – Such rubber hole plugs are generally used to disguise unintentional holes in automobiles, water tanks, refrigeration units, and other equipment fabricated with sheet metal.
There are plenty of other types of rubber hole plugs such as tubing, glossy, pry-out, D-subminiature, double-D, shorty, blanking plugs, etc.
It’s easy to find out which plug will work the best for you!
