Jones Stephens 16686 Brass Countersunk Plug 3-1/2 Inch

Product Description

The JONES STEPHENS 16686 is a brass countersunk cleanout plug designed for access cover applications requiring a flush, low-profile finish. Tapped to a 1/4-20 thread specification, this plug seats flush against the access cover surface when installed, eliminating protruding hardware that could interfere with finish work or foot traffic. At 0.25 pounds, it is a lightweight but solid brass fitting suited for drain cleanout and access cover assemblies in residential and light commercial plumbing systems. Licensed plumbers and pipe fitters install this plug as part of a cleanout assembly wherever a neat, recessed closure is required.

This countersunk plug is used in drain, waste, and vent cleanout systems where access covers must be opened periodically for inspection or rodding. The 3-1/2 inch size fits standard cleanout access cover assemblies. Its brass construction resists corrosion in wet environments, making it appropriate for use in floor drains, wall cleanouts, and similar plumbing access points in both new construction and retrofit work.

Key Features

• Countersunk profile for flush, recessed installation at access cover face
• Tapped 1/4-20 thread for secure fastener engagement
• 3-1/2 inch size fits standard cleanout access cover assemblies

Compatibility

Designed as an OEM-style replacement or new-installation component for 3-1/2 inch brass cleanout access cover assemblies in residential and light commercial drain, waste, and vent systems.

Installation Notes

Installation is performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off any flow to the drain line and verify the cleanout is not under pressure before removing or installing the plug. Use appropriate thread sealant or tape rated for brass fittings if required by the assembly design. Avoid over-tightening, which can strip the 1/4-20 tapped threads or crack surrounding cover material.
