Green Leaf F 1400 Nylon Pipe Plug 1/4 Inch Mipt

Product Description

The GREEN LEAF F 1400 is a 1/4-inch nylon plastic pipe plug designed to cap off MIPT (Male Iron Pipe Thread) pipe ends in plumbing and fluid-handling systems. Molded from white nylon, it provides a lightweight, corrosion-resistant seal suitable for low-pressure water and liquid applications. The plug meets NSF 61 and NSF 372 certification standards, making it appropriate for use in potable water systems and in applications requiring low-lead compliance. Plumbers and pipe fitters install this plug to terminate unused pipe outlets or to pressure-test portions of a system.

This plug is suited for residential and light commercial plumbing installations where a threaded cap is needed to close a 1/4-inch female-threaded pipe port. Typical applications include capping branch tees, closing off test ports, and sealing unused fittings in water distribution and fluid-conveyance piping. Its nylon construction makes it compatible with a range of non-aggressive liquids. The white color aids visual identification during inspection.

Key Features

• 1/4-inch MIPT end connection for direct threading into female-threaded pipe ports
• Nylon construction — lightweight, corrosion-resistant, and non-metallic
• NSF 61 certified for contact with potable water systems
• NSF 372 certified for low-lead compliance
• White color provides easy visual identification in the field

Compatibility

Designed as an OEM-style replacement or new-installation plug for any 1/4-inch female iron pipe thread (FIPT) fitting or port in residential and commercial plumbing systems.

Installation Notes

Installation is performed by licensed plumbers or qualified pipe fitters following applicable IPC and local plumbing code requirements. Shut off system pressure and drain the line before removing or installing any threaded fitting. Apply thread sealant tape or compound appropriate for nylon fittings, and hand-tighten before making a final snug turn with an appropriate wrench — do not overtighten nylon fittings, as the material is susceptible to thread damage from excessive torque. Verify no leaks under system operating pressure before returning the line to service.
