Sava 523942 24"-48" Multi-Size Inflatable Pipe Plug with 4 in. Bypass Product Guide

Pipe Plug Selection Notes

From a selection standpoint, the key consideration for this inflatable pipe plug is verifying compatibility within the 24" to 48" nominal pipe diameter range it covers. Since this is a multi-size plug, confirm the pipe size to be sealed falls within this range and consult size-specific backpressure ratings, as these vary across the size spectrum. The plug's construction from reinforced NR-SBR rubber with Kevlar tire cording offers wear resistance under typical commercial and municipal conditions, but users should be aware of any chemical exposure or elevated temperatures in the pipeline to determine if a chemical-resistant version is necessary. The included 4-inch bypass adds versatility for flow-through testing, so verify whether your project requires bypass capability and confirm the bypass connection fits your setup.

Inflation And Setup Planning

Plan to inspect the plug carefully before deployment for any cuts, abrasions, or damage to the rubber surface, as this can lead to failure under pressure. Use protective sleeves when inserting or retrieving the plug in pipes with abrasive or irregular surfaces to help protect the rubber. Inflation should be done through the standard tire valve fitting, inflating to the specified working pressure and maintaining that pressure for the duration of use; these plugs should not be left inflated and unattended for extended periods. Blocking or restraint planning must account for the expected backpressure, following site procedures and user manuals for support or bracing.
