Green Leaf F 1200 Nylon Pipe Plug 1/2 Inch Mipt

Product Description

The GREEN LEAF F 1200 is a 1/2-inch nylon plastic pipe plug designed to seal threaded pipe openings in plumbing and fluid-handling systems. Featuring male iron pipe thread (MIPT) end connections, this plug threads directly into a female-threaded fitting or port to cap off unused lines or pressure-test a system. The nylon construction keeps the plug lightweight and resistant to corrosion, making it suitable for water service and low-pressure piping applications. It is NSF 61 and NSF 372 certified, confirming it meets standards for drinking water system components and lead-free compliance. Plumbers and pipefitters install this type of fitting during new construction, renovation, and system isolation work.

This plug is suited for residential and light commercial plumbing systems where a reliable, low-cost threaded cap is needed on a 1/2-inch female-threaded port. Common applications include capping unused branch tees, sealing test points, and closing off fixture supply stubs during rough-in. The white nylon finish is easy to identify in a completed installation. It is appropriate for cold and ambient-temperature water lines where nylon material ratings are acceptable per local code.

Compatibility

Designed as a standard 1/2-inch MIPT threaded pipe plug compatible with female-threaded fittings and ports in residential and light commercial plumbing systems meeting NSF 61 and NSF 372 requirements.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off the water supply and relieve system pressure before installing or removing any threaded plug. Apply thread sealant tape or compound to the male threads as required by local plumbing code and the fitting manufacturer. Do not overtighten nylon fittings; hand-tight plus a partial turn with a wrench is generally sufficient to prevent cracking the fitting body.
