Sewer Air Test Plugs

Cherne® High Pressure-Plugs’ optimized design using steel, aramid and natural rubber ensure longevity through its robust construction, when high back pressures exist. Cherne I-Series Plugs have a smaller deflated diameter and shorter overall length that make it easier to insert through tight man-hole openings. All I-Series Plugs feature our Patented Field-Repairable Ruptured Disc Technology, which eliminates the risk and danger of over inflation due to faulty gauges or user error.
