The C306 Corrugated 90° Elbow is a 6-inch, single-wall HDPE fitting designed to provide a compact, reliable change of direction in corrugated drainage systems. Its hub-to-hub (HxH) configuration and short 1/4‑bend profile (approx. 3") make it ideal where space is limited and a tight radius is required.

  • Nominal size: 6 in — Hub x Hub (HxH) connection.
  • Material: Black high-density polyethylene (HDPE), single-wall corrugated construction for lightweight handling and long-term service.
  • Bend: 90° (1/4 bend) with approximately 3" centerline offset for compact routing.
  • Standards: Conforms to ASTM F405 for corrugated drainage fittings.
  • Ordering & pack: Sold individually; refer to the manufacturer catalog for carton quantities and part pricing.

Use the C306 elbow in non-pressurized drainage and stormwater lines where a short-radius 90° turn is required. It pairs with compatible corrugated tubing, external snap couplings or internal adapters as appropriate for your system; confirm pipe OD and local code requirements before final installation. See the Documents section for the manufacturer catalog and technical specifications.
