Advanced Drainage Systems 812 Aa Hdpe Snap Coupling 8 in

Product Description

The ADVANCED DRAINAGE SYSTEMS 812 AA is an 8-inch single-wall corrugated HDPE snap coupling designed to join sections of single-wall corrugated drainage pipe in the field. The snap-fit connection eliminates the need for adhesives or clamps, allowing for fast, secure assembly. This coupling is manufactured from high-density polyethylene (HDPE), which resists corrosion, soil chemicals, and UV degradation. It is a standard fitting used by plumbers, site contractors, and drainage installers working on residential and light commercial stormwater and subsurface drainage systems.

This snap coupling is suited for use with 8-inch single-wall corrugated HDPE drainage pipe in applications such as foundation drainage, yard drainage, roadside ditches, and agricultural runoff management. The coupling is typically installed below grade or at grade in trench or open-ditch configurations. It is commonly used wherever a mechanical, tool-free pipe joint is needed on corrugated single-wall pipe runs.

Key Features

• 8-inch diameter fits standard single-wall corrugated HDPE pipe
• Snap-fit design requires no adhesives, solvents, or clamps
• HDPE construction resists corrosion, chemicals, and soil contact
• Lightweight and easy to handle in trench or ditch installations
• Compatible with corrugated pipe profiles for secure, low-profile coupling

Compatibility

Designed as an OEM-style replacement and field fitting for 8-inch single-wall corrugated HDPE drainage pipe installations.

Installation Notes

This coupling is typically installed by plumbers, drainage contractors, or site utility crews working under local plumbing or grading codes. Before installation, ensure the pipe ends are clean and free of debris so the snap connection seats fully around the corrugated profile. No solvents or special tools are required, but proper trench bedding and backfill practices should follow local site and drainage specifications. Always verify local code requirements for subsurface drainage fittings before installation.
