High-Temperature Round Plugs for NPT Pipe
These plugs withstand temperatures up to 600° F to protect internally threaded NPT connections from contaminants during electroplating, paint baking, and powder coating applications. All have a tear-away nipple that allows pressure to release during curing. Install these plugs manually or with a square-drive wrench or socket.
