Blockers
Stemar blocking plugs are used in "blocking only" applications where flow stoppage is the only action required from the plug.
Selecting the optimal blocking plug for your job can mean a world of difference. Savvy and proper use of the correct pipe plug can make or break the profit on a job. Many plug failures are simply due to selecting the wrong type or model of plug. We can help you select the optimal plug specific to your application and jobsite needs.
Common applications for Stemar blocking include blocking sewer flow for pipeline rehabilitation, manhole repairs, wet-well style trash pump bypassing, blocking sewer odors & vapors, and riser-style water testing.
Upon request we can include EPDM, Nitrile, Stainless Steel, and/or other materials to the blocking plug manufacturing process in order to add hydrocarbon and/or other chemically resistant properties to your custom plug. Chemical compositions, temperatures, PH levels, techniques and/or durations we receive to design and build your custom plugs will be held under complete confidentiality.
