Legend LEGE-302-629 Countersunk Cleanout Plug 4in Mnpt Brass

Product Description

The LEGEND LEGE-302-629 is a countersunk cleanout plug designed for drain, waste, and vent (DWV) piping systems. Constructed from brass, this plug features a male NPT (MNPT) end style that threads directly into a cleanout fitting or adapter. The countersunk head profile sits flush or below the surrounding surface, making it well suited for floor-level or concealed cleanout installations. At 4.45 inches in diameter with a 4-inch nominal size, it fits standard 4-inch DWV cleanout openings. Plumbers install this plug to seal cleanout access points between service intervals, maintaining a watertight and low-pressure-rated closure rated for under 10 psi cold working pressure in DWV service.

This plug is used in residential and light commercial drain, waste, and vent systems where a 4-inch nominal cleanout is required. Typical applications include floor cleanouts in slab construction, wall cleanouts in drain stacks, and building drain cleanout terminations. The brass construction resists corrosion in wet environments and provides durable thread engagement over repeated service cycles. The countersunk head design is particularly useful in installations where a raised plug head would obstruct foot traffic or conflict with finish flooring.

Key Features

Compatibility

Designed as an OEM-style replacement or new-installation component for standard 4-inch nominal MNPT cleanout fittings in residential and commercial DWV piping systems.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Before removing or installing the cleanout plug, confirm the drain system is depressurized and flow has been stopped upstream. Apply thread sealant or PTFE tape to the MNPT threads before installation to ensure a leak-free seal. Do not overtighten brass threaded fittings, as brass threads can be damaged by excessive torque.
