Product Description

The ADVANCED DRAINAGE SYSTEMS 390 AA is a 3-inch single wall corrugated HDPE snap-fit 90-degree elbow designed for stormwater drainage and subsurface drainage applications. The snap connection allows for tool-free assembly, making it a practical choice for fast installations. Constructed from high-density polyethylene (HDPE), the fitting offers resistance to moisture, soil chemicals, and typical ground-level impact loads. This elbow is installed by plumbers, drainage contractors, and site utility crews working on residential and light commercial drainage systems.

The 390 AA is suited for use in residential yard drainage, downspout drainage runs, french drain layouts, and other gravity-flow stormwater management systems requiring a 90-degree direction change in 3-inch single wall corrugated pipe. The snap-fit design integrates with compatible single wall corrugated pipe and fittings in the same size family. It is a common component in shallow burial and surface drainage applications where single wall corrugated pipe is the specified product.

Key Features

• 3-inch pipe size fits standard single wall corrugated HDPE drainage pipe
• Snap-fit connection allows tool-free, hand-press assembly
• 90-degree elbow geometry for sharp directional changes in drainage runs
• HDPE construction resists moisture, corrosion, and common soil chemicals
• Lightweight design reduces handling effort on large drainage installations

Compatibility

Designed for use with 3-inch single wall corrugated HDPE drainage pipe and fittings using a snap-fit connection style. Intended for gravity-flow stormwater and subsurface drainage systems.

Installation Notes

Installation is typically performed by plumbers or drainage contractors following local stormwater and grading codes. Ensure the pipe end is clean and fully seated before snapping the fitting into place. Confirm pipe alignment and grade before backfilling to maintain proper flow direction. No special tools are required for the snap connection, but care should be taken not to overtorque or force misaligned sections.
