Pipe caps thread onto the outside of male pipe ends to seal them against leakage, contamination, or pressure loss. This cap ships in a package quantity of 25 units, making it practical for job-lot stocking and multi-point installations. Licensed plumbers, pipefitters, and HVAC technicians commonly use black pipe caps when capping off unused branch lines or during system pressure testing.
