Driving cap

A driving cap is a special type of

pipe cap

and is always removed once installation is complete.

Driving caps serve no function in the operation of a pipe and may even be incapable of doing so. This is because the driving cap is cast from a material selected for its strength and not its corrosion resistance. Thus replacement of the driving cap with a different fitting becomes necessary to prevent failures in materials handling pipe. Also, driving caps are not attractive in appearance, which is detrimental in residential and ornamental applications.
