THE SSB PLUGS were developed to block sewer lines during an air test, or for blocking flows. These are the most economical inflatable plugs available.
These plugs are designed with a newly formulated natural rubber compound, making them the toughest and most dependable single size plugs available. Like the SST, the SSB plugs come with a removable 3/8″ eyebolt and a removable 1/4″ NPT tire inflation valve.
