Sava 529411 24"-40" Multi-Size Pillow Style Large Diameter Inflatable Pipe Plug Product Guide

Pipe Plug Selection Notes

Selecting the right size within the 24" to 40" nominal diameter range is essential for this multi-size pillow-style inflatable plug. Confirm backpressure against the size-specific chart or manual for the selected pipe diameter, and keep that check separate from the specified inflation pressure. Confirm that pipe access points such as manholes allow insertion of the deflated pillow plug, typically requiring an opening about one-third the pipe diameter.

Pipe Access And Setup Planning

Inspect the plug carefully before use for any cuts or abrasions in the rubber, as these can compromise inflation and sealing under pressure. Use a protective sleeve if pipe entry surfaces are rough or abrasive to avoid damage during insertion or removal. Inflate the plug to the specified working pressure and maintain that pressure throughout use by monitoring the standard 1/4 inch inflation fitting. Blocking or restraint methods should be planned following the user and safety manual to manage backpressure during operation.
