Multi-Flex™ Inflatable Pipe Plugs (All pipe sizes and shapes)

These Multi-Flex™ Plugs come in various configurations and pressure ratings. They are the most flexible plugs on the market with the greatest multi-size range. They conform to almost any pipe configuration and can fit through very confined spaces. When completely deflated, a 96" plug will deflate down to only 12"! The very small-deflated diameter and flexibility allows insertion and removal through a manhole or a live hot tap for plugging otherwise inaccessible pipelines.

The Multi-Flex™ Plug may be used in a pipe smaller than the maximum rated inflation diameter. Since a minimal inflation pressure with water, air or other inert gas will expand the plug to its full diameter, most of the pressure is available to seal and lock the plug in place. The Multi-Flex™ Plug will generally conform to almost any pipe configuration. The Multi-Flex™ Plugs are available with or without a flow-thru by-pass.

These Plugs may be customized for most pressure, chemical, and temperature requirements.
