Introducing the Advanced Drainage Systems 6 in. Snap x 7 in. D Snap Polyethylene Corrugated-to-Clay Pipe Adapter (1 piece). Built to connect a 6-inch corrugated drainage pipe to a 7-inch clay pipe, this adapter is designed for underground installations where reliability and a fast, secure joint matter most. Crafted from durable polyethylene, it handles the rigors of burial environments while resisting the corrosion that can plague metal or improvised connections.
Key benefits that address real drainage needs
-
Snap-to-snap integration on both ends provides a quick, tool-free connection. No glues, solvents, or clamps needed—perfect for on-site installations where speed matters.
-
6" to 7" diameter transition clearly labeled ends (End 1: 6" diameter, Snap; End 2: 7" diameter, Snap) ensure a precise fit between corrugated pipe and clay pipe, reducing the chance of leaks at the joint.
-
Underground-rated performance designed for buried drainage work, providing a stable, long-lasting bridge between different pipe systems in yards, basements, and landscape drainage projects.
-
Lead-free polyethylene minimizes environmental concerns and aligns with common plumbing and drainage material standards.
-
ANSI certified compliance offers reassurance about meeting established industry requirements, while noting that IAPMO certification is not included for this item.
-
Single-piece package with bagged packaging simplifies handling on-site and helps prevent loss of small components during installation.
Why this adapter makes sense for your project
-
Ideal for retrofits and new installs where you need to tie a modern corrugated drainage line into an older clay main without reconfiguring existing piping.
-
Versatile use cases in residential yards, driveways, basements, and other underground drainage applications where a reliable corrugated-to-clay connection is required.
-
Durable, predictable performance from polyethylene construction helps you avoid corrosion, spalling, or joint failures common with incompatible materials.
