ABS Threaded Cleanout Plugs

Recessed

Close off your drain cleanout pipe with these threaded plugs. Note: If you do not know your pipe size, measure the OD of your existing cleanout plug or the ID of your cleanout fitting and match to the value listed.

To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For metal threads, use PTFE tape. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.

Low-Profile Fully-Threaded Standoff Caps

Standoff Cap

Installation Tools

A thin head means these caps sit nearly flush with your surface for a clean look. All caps are aluminum and have good corrosion resistance, are lightweight, and are nonmagnetic.

Standoff Cap Installation Tools—Installation tools (sold separately) make gripping and tightening easy.
