The skirts on the new CE Series pipe caps are designed to stretch over the pipe edges while retaining their shape and tight fit. This feature allows them to be installed without tools. Ribbed skirts provide ventilation to ensure that the caps will not blow off under pressure. The pipe caps are made of linear low-density polyethylene, and are available in a range of sizes. — Caplugs, Buffalo, N.Y.
