Advanced Drainage Systems 0862ST Hdpe Soiltight Tee 8 in

Product Description

The ADVANCED DRAINAGE SYSTEMS 0862ST is an 8-inch HDPE soiltight tee fitting designed for use with ADS N-12 corrugated drainage pipe. This tee provides a branch connection in underground stormwater and site drainage systems, maintaining a soiltight seal that prevents soil intrusion at the joint while allowing controlled water flow through the pipe network. It is installed by plumbers, civil contractors, and site drainage specialists working on residential, commercial, and municipal drainage projects.

This fitting is used in subsurface drainage applications where a branch outlet is needed in a main drainage run. Typical installations include stormwater conveyance systems, foundation drainage, parking lot drainage, and other below-grade gravity-flow applications. The soiltight joint rating makes it suitable for installations where preventing soil infiltration at connections is required, but a watertight seal is not specified.

Key Features

• 8-inch nominal size matches standard ADS N-12 corrugated HDPE pipe diameter
• Soiltight joint rating prevents soil intrusion at the connection point
• HDPE construction resists corrosion, root intrusion, and chemical degradation common in below-grade environments
• Tee configuration allows a branch connection off a main drainage run without cutting into the flow path
• Compatible with corrugated N-12 pipe for use in gravity-flow drainage systems

Compatibility

Designed for use with ADS N-12 8-inch corrugated HDPE drainage pipe in soiltight drainage system applications.

Installation Notes

Installation is typically performed by licensed plumbers or site drainage contractors following local stormwater and drainage codes. Before installing or modifying any below-grade drainage connection, confirm the system is depressurized and not actively conveying flow. Proper bedding and backfill practices per project specifications should be followed to prevent joint displacement under load. Do not exceed the pipe system's rated burial depth or load rating.
