The CAPLUGS 14226 is a mechanical plug designed to seal open-ended pipes at a 1-5/8 inch pipe size. It provides a secure, temporary or permanent closure for pipe ends during storage, shipping, or installation work. Plumbers, pipefitters, and general contractors use this type of plug to keep debris, moisture, and contaminants out of open pipe runs. The plug seats mechanically, meaning it does not rely on adhesives or threading alone for retention. It is sold in a package quantity of 25 units, making it practical for job-site use where multiple pipes require protection.
This plug is appropriate for residential and commercial plumbing applications wherever open pipe ends need to be capped or protected. Common use cases include new construction rough-in work, pipe storage in fabrication shops, and temporary closures during phased installations. The 1-5/8 inch sizing is suited for standard pipe runs in plumbing and mechanical systems.
Designed as an OEM-style mechanical plug for open-ended pipes at the 1-5/8 inch pipe size in plumbing and mechanical piping systems.
Pipe mechanical plugs of this type are typically installed by licensed plumbers or pipefitters. Ensure the pipe end is clean and free of burrs or debris before seating the plug to achieve a proper fit. No special tools are required for standard installation, though gloves are recommended when working with sharp-edged pipe ends. Follow applicable IPC and local plumbing code requirements for any permanent closures on pressurized systems.
