How the 137 Series Pipe Blocking Plug Works?
The 137 Series Pipe Blocking Plug is designed for temporary pipe sealing, pressure testing, and leak detection. Its expanded rubber structure enables it to fit securely in a variety of pipe sizes and materials.To use, insert the plug into the pipe opening, making sure it's properly placed. Then, inflate it using a Schrader valve or BSPT fitting. As the plug expands, it creates a tight, secure seal, effectively restricting flow or containing pressure during testing.
The plug on bypass variants allows for controlled flow-through, making it excellent for pressure testing and drainage management. After testing or maintenance is completed, deflate the plug and remove it without damaging the pipe.
Applications
