Advanced Drainage Systems 321 Aa Hdpe Snap Tee 3 Inches

Product Description

The ADVANCED DRAINAGE SYSTEMS 321 AA is a 3-inch single-wall corrugated HDPE snap tee designed for drainage piping applications. This fitting connects branch lines to main drain runs using a tool-free snap-fit assembly, making field installation fast and reliable. The high-density polyethylene construction resists corrosion, soil chemicals, and moisture — common challenges in underground and surface drainage work. Licensed plumbers, drainage contractors, and site utility crews are the primary installers of this type of fitting in both residential and light commercial projects.

This snap tee is used in 3-inch single-wall corrugated drainage systems, typically in yard drainage, French drain networks, foundation drainage, and storm water management installations. The snap-fit design eliminates the need for solvent cement or mechanical fasteners at the branch connection, allowing crews to make quick, secure tee connections during trenching and pipe-laying operations. It is suited for non-pressure, gravity-flow drainage service.

Key Features

• 3-inch nominal size fits standard single-wall corrugated HDPE drainage pipe
• Snap-fit connection provides tool-free assembly at the branch fitting
• HDPE material offers corrosion resistance and long service life in buried applications
• Single-wall corrugated construction keeps the fitting lightweight and easy to handle
• Gravity-flow design appropriate for yard, French drain, and storm drainage systems

Compatibility

Designed as an OEM-style fitting for use with 3-inch single-wall corrugated HDPE drainage pipe systems in gravity-flow drainage applications.

Installation Notes

Installation is typically performed by licensed plumbers or drainage contractors following local plumbing and site drainage codes. Ensure the main drain pipe run is properly bedded and that all corrugation ridges are fully engaged before snapping the tee into place. Always verify that the system is depressurized and free of water flow before making or modifying connections. This fitting is rated for gravity-flow drainage only and must not be used in pressurized piping systems.
