Sava 535874 24"-48" Multi-Size Inflatable Pipe Plug with 8 in. Bypass Product Guide

Pipe Plug Selection Notes

The Sava 535874 covers a wide nominal pipe diameter range from 24 to 48 inches, making it suited for applications where a single plug must adapt to varying pipe sizes within that range. When selecting this plug, verify the exact pipe size within this range because backpressure ratings and inflation pressures vary depending on the pipe diameter used. The 8-inch bypass provides a flow path for pressure testing or partial flow while the plug is installed, so confirm your project’s need for bypass functionality before choosing. Check the compatibility of the NR-SBR rubber, reinforced with Kevlar cording, especially if the pipe contents may involve chemicals or elevated temperatures, as chemical-resistant versions exist separately.

Pipe Access And Setup Planning

Plan access to the pipe opening large enough to accommodate the deflated plug and the 8-inch bypass fitting. Inspect the plug before use for any cuts, abrasions, or rubber damage that could affect inflation or sealing performance. Use protective sleeves if pipe interiors are rough or contain irregularities to prevent premature wear during insertion or removal. Inflate the plug to the specified working pressure and monitor inflation pressure during use, maintaining it as required to prevent loss of seal or plug slippage.
