3″ & 3-1/2″ Mechanical Cleanout Gripper Plug Set – 2-Pack

Designed for quick, reliable sealing of DWV cleanout access points, this 2‑pack set from kiecpoy includes 3‑inch and 3‑1/2‑inch rubber plugs that expand mechanically when tightened. The bolt‑driven expansion creates a firm, leak‑tight seal, allowing temporary blockage of sewer gas and water flow while still permitting easy removal for inspections or maintenance.

Each plug is built for repeated use, making them ideal for maintenance crews and homeowners alike. The dual‑size configuration covers the most common drain dimensions, providing flexibility for a variety of plumbing configurations. Whether you need to seal a temporary opening or maintain a cleanout for future access, these plugs deliver a secure fit without the need for permanent pipe modifications.
