A driving cap is a special type of
pipe cap used to provide a striking surface for a hammer while simultaneously protecting the end of the pipe from
deformation.
A driving cap is made of much thicker or more durable material than a standard
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
Cast may refer to:
Music
* Cast (band), an English alternative rock band
* Cast (Mexican band), a progressive Mexican rock band
* The Cast, a Scottish musical duo: Mairi Campbell and Dave Francis
* ''Cast'', a 2012 album by Trespassers William ...
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.
