• Constructed of lightweight aluminum, gauges will not rust and are 75% lighter than comparable steel models.
• Sets includes mandrel assembly, fins sets, & case.
• Single size aluminum or steel deflection gauges are also available
• Accurately sized to 0.1" to meet ASTM requirements

DEFLECTION GAUGE OVERVIEW

Deflection Gauges (mandrels) are used to test flexible sewer pipes for out-of-roundness or deflection. This testing ensures that flexible pipe has been properly bedded and back-filled to give optimum performance. (Per ASTM Designation D2321-89)

Why test? Because deflected pipe creates problems in cleaning and televising sewer lines. It also can cause sand and silt to accumulate resulting in pipe blockage. Deflected pipe indicates improper back-filling methods or materials were used during installation.
