Sava 529413 48"-64" Multi-Size Pillow Style Large Diameter Inflatable Pipe Plug Product Guide

Pipe Plug Selection Notes

From a selection standpoint, the 529413 plug covers a wide diameter range from 48 to 64 inches, making it suited for large pipes where access may be limited. It uses a pillow-style inflatable design using NR-SBR rubber reinforced with Kevlar tire cording. When selecting this plug, verify that the pipe diameter falls within the stated multi-size range and that pipe conditions allow correct seating of a pillow-style 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.

Pipe Access And Setup Planning

Plan to inspect the plug carefully before deployment for any cuts, abrasions, or damage in the rubber, as even minor surface issues can lead to failure. Use protective sleeves if pipe surfaces are rough or abrasive to prevent damage during insertion and removal. Inflation should be done through the standard 1/4 inch male fitting, and the inflation pressure monitored and maintained throughout the operation. Blocking or restraint planning should align with user manuals and site procedures to address backpressure forces.
