Product Description

The ADVANCED DRAINAGE SYSTEMS 614 AA is a single-wall corrugated HDPE reducing coupling designed to connect 6-inch corrugated pipe to 4-inch corrugated pipe in drainage and stormwater management applications. Fabricated from high-density polyethylene (HDPE), this fitting delivers corrosion resistance and flexibility suited to below-grade and surface drainage installations. Licensed plumbers, drainage contractors, and site utility crews install this coupling where pipe diameter transitions are required in a single-wall corrugated system. The lightweight HDPE construction simplifies handling and speeds up field assembly without tools in most cases.

This reducing coupling is used in residential and light commercial drainage systems, including yard drainage, downspout runoff lines, French drain assemblies, and culvert connections. It is suited for installations where a 6-inch mainline must step down to a 4-inch lateral or outlet. The single-wall corrugated design matches standard single-wall corrugated pipe profiles commonly used in non-pressure, gravity-flow drainage applications.

Key Features

• Reduces from 6-inch to 4-inch corrugated pipe in a single fitting
• Single-wall corrugated HDPE construction resists corrosion and soil chemicals
• Lightweight design simplifies handling and positioning during installation
• Compatible with standard single-wall corrugated pipe profiles
• Suitable for gravity-flow, non-pressure drainage applications

Compatibility

Designed as an OEM-style fitting for single-wall corrugated HDPE drainage pipe systems, providing a 6-inch to 4-inch diameter reduction in gravity-flow drainage installations.

Installation Notes

Installation is typically performed by licensed plumbers, drainage contractors, or site utility crews following applicable local plumbing and grading codes. Power-driven equipment is not required for fitting assembly, but ensure the pipe ends are clean and seated fully into the coupling before backfilling. Do not use this coupling in pressurized pipe systems. Verify local code requirements for burial depth and bedding material before covering the installation.
