Pipeline Deflection Gauges, 938-96 Series
Steel Fixed Size and Aluminum Fin & Mandrel Deflection Gauges test flexible sewer pipe for out-of-roundness or deflection per ASTM specifications D3034 and F679.
- Tests flexible pipe has been properly bedded and backfilled (ASTM D2321)
- Sized to .01" both deflection gauge styles meet ASTM requirements.
- 5% and & 7.5% Tolerance available
- All sizes fit through standard 24" manhole
- Nine-arm design ensures testing accuracy
- Open design allows gravel and debris pass-through
- Other gauges can get hung up - causing a deflection test to fail, even though the pipe is within tolerance
- Custom sizes available
FILL OUT THIS ORDER FORM when ordering Deflection Gauges.
Fixed Steel Style Deflection Gauges
- Durable, zinc-plated construction resists corrosion
- Conforms to mandrel sizing specifications-blade length is equal to or greater than the nominal pipe size
- Nine-arm design ensures testing accuracy
- Open design allows gravel and debris pass-through

Aluminum Fin Deflection Gauges
- Lightweight, corrosion-resistant
- Field-verifiable without a proving ring
- Assembles without tools
- Fins for 4"-15" gauges have skid size equal to the nominal pipe size-gauge to meet regional codes and will not tip in the line
Field Verification:
Fin Style Deflection Gauges are designed to be field verified by inspectors without the use of a proving ring. Simply place two fins end to end as pictured to the right and measure the width.
Add one inch to the mandrel and you have the outside dimension of the gauge. Using this method simplifies the inspector's job of verifying sizes on deflection gauges.

Proving Rings
Proving rings allow an inspector to verify the outside diameter of the gauges to make sure it slides over snugly to prove the diameter of the gauge and allow it to be used for the test.
- Used to verify deflection gauge sizes
- Standard sizes: 6"-15" SDR 35 5% deflection and 8"-12" SDR 35 7.5% deflection
- Custom sizes: Custom sizes for 5"-18" also available
