china threaded plug for drain cleanout

The threaded plug for drain cleanout provides a removable, leak-tight seal for accessing sewer or waste pipe branch lines. Machined from cast iron, PVC, or brass, these plugs fit standard cleanout tee openings (typically 2 to 4 inches NPT or IPS threads). The square or raised-head design allows easy turning with a pipe wrench or cleanout plug tool. Many plugs include a rubber O-ring or recessed gasket to improve sealing without requiring pipe dope, though Teflon tape is still recommended for metal threads. For tight spaces, countersunk flush plugs are available that sit level with the fitting
