Threaded Round Plugs for Straight-Thread Pipe
Seal tube and hose fittings to keep their straight threads protected from contaminants during fabrication and storage.
Aluminum plugs withstand temperatures up to 650° F, which is more than four times as high as polyethylene and nylon plugs. They are also more abrasion resistant. Install them manually.
