The Petersen® PeteStop® 129-Series Line Stop is our best selling system. It is a great choice to complement a mechanical stop or use in place of because of its savings in time, money and lighter, more flexible installation. Plus the PeteStop® Inflatable Line Stop is able to handle more difficult pipe conditions where a mechanical stop would be unable to get a workable seal.

The Petersen Products® MULTI-FLEX® is the most flexible pipe plug on the market; with the greatest multi-size range and ability to conform to almost any pipe configuration - a 36” MULTI-FLEX® plug will also stopper a 10” pipeline! MULTI-FLEX® pipe plugs are built with lightweight high-strength materials that fit through very small openings and easily weave around bends. Inflate with gas or liquid for multi-size pipe diameters with all the inflation pressure applied to the inside of the pipe wall. Some Multi-Flex® plugs can be connected in series for block and bleed applications. Whatever your situation, the pipe plug can be customized for most sizes, pressures, temperatures, and chemicals. To determine the best MULTI-FLEX® pipe plug for your job check out the Multi-Flex® Pipe Plug Comparison Chart or contact us with your requirements.
