Description
PVC DWV Square Head Cleanout Plug (MPT)
PVC DWV Square Head Cleanout Plug (MPT) provides a removable threaded closure for compatible PVC DWV cleanout fittings. The male pipe-threaded connection installs into an appropriately sized compatible female-threaded opening, while the square head provides a gripping surface for installation and future removal.
The MPT cleanout plug configuration is designed to close a compatible threaded cleanout opening while maintaining service access to the piping system. Selection should account for nominal size, thread compatibility, cleanout accessibility, installation clearance, adjoining fitting condition, and future removal requirements.

Cleanout Plug Design
The cleanout plug configuration provides a removable closure for a compatible threaded cleanout opening. This allows the piping system to remain closed during normal service while preserving access for inspection, cleaning, or maintenance when required.
The plug should be selected to match the nominal size and female-threaded cleanout fitting. Planning the cleanout location helps maintain adequate access for installation, tightening, inspection, and future removal.
Square Head & MPT Connection
The square head provides a defined gripping surface for installing or removing the plug, while the male pipe-threaded connection engages the corresponding compatible female thread. The mating threads should be inspected before assembly.
The plug should be started carefully by hand and kept properly aligned to avoid cross-threading. Compatible thread-sealing materials should be selected according to the installation requirements and adjoining fitting material.
PVC DWV Integration
The PVC DWV construction allows the cleanout plug to integrate into compatible drain, waste, and vent piping arrangements requiring removable threaded access. Matching the nominal size and thread interface to the adjoining cleanout fitting helps maintain the intended closure.
Application suitability should be evaluated using the requirements of the complete DWV system. Thread compatibility, cleanout accessibility, adjoining materials, sealing requirements, and local installation practices should all be considered during plug selection.
Removable Service Access
A PVC DWV Square Head Cleanout Plug provides a serviceable closure that can be removed when access to the piping system is required. The square head should remain accessible so maintenance personnel can reach the plug without unnecessary obstruction.
Installation planning should consider tool clearance, surrounding construction, thread engagement, and future service requirements. The cleanout location should not be concealed or blocked where access is required by the installation.
Installation & Selection Considerations
- Confirm the nominal size.
- Verify the MPT connection.
- Check PVC DWV compatibility.
- Match the plug to the female thread.
- Maintain access for future removal.

Our PVC fitting specialists can help review your nominal size, DWV requirements, MPT connection, mating female thread, cleanout accessibility, sealing requirements, installation clearance, and future service needs before you order.
