The Petersen® 938-96 Series 8" Deflection Gauge with Aluminum Fins is a robust tool designed for testing flexible sewer pipes for out-of-roundness and deflection, meeting ASTM specifications D3034 and F679. With a nine-arm design ensuring accurate testing, this gauge allows gravel and debris to pass through easily, preventing hang-ups that can lead to test failures even when the pipe is within tolerance. Lightweight and corrosion-resistant, this gauge is field-verifiable without a proving ring and assembles without tools. It fits through standard 24" manholes and features fins for gauges in the 4"-15" range with a skid size equal to the nominal pipe size, ensuring compliance with regional codes and stability in the line.
