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 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.

“On a late-winter evening in 1983, while driving through fog along the Maine coast, recollections of old campfires began to drift into the March mist, and I thought of the Abnaki Indians of the Algonquin tribe who dwelt near Bangor a thousand years ago.”

“In time your relatives will come to accept the idea that a career is as important to you as your family. Of course, in time the polar ice cap will melt.”
