- The plugs often have a hexagonal head or another type of suitable shape to enable easy tightening using a wrench or similar tool.
- Some compression plugs may have a flanged end or other specialized features to facilitate their use in specific applications.
Materials:
- Compression fitting plugs are manufactured using a variety of materials, including stainless steel, brass, aluminum, plastic, and other materials suitable for the intended application.
- The material chosen often depends on factors such as the environment, the type of fluid or gas being transported, temperature, and pressure requirements.
Installation:
- To install a compression fitting plug, it is threaded into the open end of the pipe, tube, or system and tightened using an appropriate tool.
- The compression action creates a secure seal, preventing any substance from leaking out or entering the system.
Applications:
- Compression fitting plugs find application in various industries, including plumbing, HVAC (heating, ventilation, and air conditioning), hydraulic and pneumatic systems, automotive, and more.
- They are used in pipes, tubes, and systems that carry liquids, gases, or other substances under pressure.
Advantages:
- Compression fitting plugs offer a reliable and straightforward solution for closing off pipes or systems, providing a secure seal and preventing leaks.

User questions & answers
| Question: | Is this a dot rated tank? does it have a stamp or badge on it saying so |
| Answer: | Yes. You can attach an air line directly to the tank, by shopping for the size fittings and pipe supply that it will require, at a hardware store. However, if you want to mount the pump itself directly to the tank, you will need to weld two platforms onto the tank, to hold the pump and the electric motor. The tank can be pumped up to 175lbs of pressure. |
