Pneumatic Pipe Isolation

Medium Pressure Inflatable Pipe Plug

A fast, flexible way to temporarily block a line for maintenance, repairs, and testing. Snake it into large or hard-to-reach pipe, inflate it with a standard air source, and get a tight seal with no special tools, permanent changes, or shutdowns.

Why Inflatable Plugs

Block the Line. Skip the Shutdown.

Pipe BlockageStop liquid or gas flow without permanent changes or a system shutdown.

VersatilitySewer, stormwater, industrial, and plumbing lines. Snakes into large or hard-to-reach pipe.

Easy InstallA simple inflation valve and standard air source. No specialized tools.

Tight SealPrevents leaks, spills, and contamination while you work.

Cost-EffectiveCosts less than mechanical plugs or hot taps, and it's reusable.

SafetyDurable construction that deflates and removes easily.

Know the LimitsNever inflate beyond the maximum pressure listed for each plug. Inflatable plugs hold only a few psi of back pressure. We don't recommend them for back pressure unless the fluid is water and a failure would have negligible impact. Never stand in front of a plugged line.

Need to Hold Back Pressure?

Step Up to GripSafe®

For isolation or testing against real line pressure, use a mechanical isolation and test plug.

Common Questions

Inflatable Plug FAQ

Can I get an inflatable plug with vent-through capability?

Not usually on this style, but we can supply a different style of plug that vents through. Ask our team.

What is the largest size you provide?

Up to 96". For larger lines, we can recommend other isolation solutions.

Can I get a longer fill hose?

Yes. Each plug comes with a 2 ft. hose. Tell us the length you need.

What is the heat rating?

Heat-resistant versions are rated up to 200°F.

Will these hold back pressure?

Only a few psi. We don't recommend them for back pressure unless the fluid is water and a failure would have negligible impact. For real back pressure, use a GripSafe® ST plug.

Is the plug repairable?

Only the inner fill valve stem can be repaired.
