Jones Stephens 1684C Brass Countersunk Cleanout Plug

Product Description

The JONES STEPHENS 1684C is a brass countersunk cleanout plug designed for use with 4-inch cleanout access covers. The plug features a countersunk profile and a 1/4-20 tapped hole, allowing it to be seated flush with the cover face and secured with a standard flat-head machine screw. Constructed from solid brass, it provides corrosion resistance in drain, waste, and vent applications. Licensed plumbers and drain service technicians install this plug as part of a cleanout assembly in residential and light commercial piping systems.

This plug is used in plumbing drain, waste, and vent systems where a flush, recessed plug is required on a 4-inch cleanout access cover. The countersunk design keeps the plug face flush with the surrounding surface, which is practical in finished floor or wall installations. The 1/4-20 tapped center hole accepts a standard machine screw for secure retention and easy removal during drain cleaning or inspection service calls.
