The Petersen 938-96 Series 12-Inch Deflection Gauge with Aluminum Fins is designed to test flexible sewer pipes for out-of-roundness and deflection adherence per ASTM specifications D3034 and F679.

Lightweight, corrosion-resistant, and field-verifiable without a proving ring, this gauge meets ASTM requirements and fits through standard 24 manholes. With fins designed to prevent tipping in the line and stringer compatibility for quick line stringing between manholes, this gauge guarantees optimal performance and compliance with industry standards.
