Sava 535882 32"-72" Multi-Size Inflatable Pipe Plug with 4 in. Bypass Product Guide

Pipe Plug Selection Notes

From a selection standpoint, this multi-size inflatable pipe plug covers a large nominal pipe diameter range from 32 to 72 inches, making it applicable for many industrial and municipal pipe blocking tasks. Because it includes a 4 inch bypass connection, it supports flow-through or bypass operations, which require verification of the bypass connection compatibility and job-specific flow needs. The plug’s NR-SBR rubber with Kevlar reinforcement helps it withstand backpressure at triple the working inflation pressure, but backpressure ratings should be confirmed from the manufacturer’s size-specific charts or manuals for the selected pipe diameter. When selecting, check the condition of the pipe surface and confirm that the plug size setting fits well within the stated range for correct sealing and inflation pressure control.

Inflation And Blocking Planning

Before each use, inspect the inflatable pipe plug carefully for any cuts, abrasions, cracks, or signs of rubber damage that could compromise performance. Use protective sleeves if pipe surface conditions are rough or abrasive. Inflate the plug to the specified working pressure via the standard tire valve fitting, and regularly monitor and maintain this inflation pressure during operation as the plug should not be left inflated and unattended for long periods. Because of the potential forces generated by backpressure and flow, plan for compatible blocking, bracing, or restraint per the user and safety manual.
