Pipe caps come in diameters from 1/4 to 64 in. and five designs. OE and CE Series caps protect pipe threads during transit and storage. OE caps are open-ended for airflow, and CE caps are closed-ended to keep out debris. VP closed-ended caps have a small hole to allow venting and avoid pressure buildup. EP open-ended caps protect pipes with beveled edges while maintaining airflow through the pipe.
