Advanced Drainage Systems 0899WT 8 in Hdpe 90 Deg Elbow

Product Description

The ADVANCED DRAINAGE SYSTEMS 0899WT is an 8-inch HDPE watertight 90-degree elbow fitting designed for use with ADS N-12 dual-wall corrugated pipe systems. This fitting provides a sealed, watertight directional change in underground storm drainage and stormwater management installations. Manufactured from high-density polyethylene (HDPE), it delivers corrosion resistance and long service life in buried applications. Licensed plumbers, drainage contractors, and site civil crews install this fitting during stormwater conveyance and subsurface drainage system construction.

This fitting is intended for use in residential, commercial, and municipal storm drainage systems where a 90-degree change in pipe direction is required. It is compatible with ADS N-12 dual-wall corrugated HDPE pipe in the 8-inch diameter. The watertight joint design makes it appropriate for applications requiring groundwater infiltration control or pipe joint leakage prevention in subsurface installations.

Key Features

• Watertight joint design prevents groundwater infiltration and exfiltration at the connection
• 90-degree elbow provides a right-angle directional change in drainage runs
• HDPE construction resists corrosion, chemicals, and abrasion in buried environments
• Designed for use with ADS N-12 dual-wall corrugated pipe systems
• 8-inch pipe diameter suits high-flow residential and light commercial drainage applications

Compatibility

Designed for use with ADS N-12 dual-wall corrugated HDPE pipe in the 8-inch nominal diameter.

Installation Notes

Installation should be performed by a qualified drainage contractor or licensed plumber in accordance with applicable local plumbing and site drainage codes. Ensure the pipe ends are clean and properly seated before securing the watertight gasket connection. Follow proper bedding and backfill practices per ASTM and manufacturer guidelines to prevent joint deflection in buried applications. Do not exceed the pipe system's rated depth of cover or load capacity.
