What is a pipe plug?

A pipe plug is a type of threaded tool used to seal pipelines in various applications and prevent flow. Pipe plugs are commonly used for maintenance, line testing, construction and more.

How do you use a test ball plug?

Test ball plugs are a type of pneumatic pipe plug, designed to be inflated and deflated for quick, temporary use. They are suitable for use in a variety of pipe sizes. Simply insert and position the deflated test ball plug into the necessary pipe, then expand to the necessary pressure. Because test ball plugs are temporary, it is recommended to check inflation pressure every couple of hours.

How are pipe plugs measured?

To find the correct pipe plug for your pipe, measure the pipe's inside diameter. Then, subtract ¼ of an inch to find that pipe’s nominal size. Then, using a National Pipe Tapered (NPT) thread chart, find the measured thread diameter to determine the corresponding nominal pipe plug size. Need more help?
