Nds 1241 Universal Corrugated Adapter 3 4 Inch Spigot

Product Description

The NDS 1241 is a universal corrugated adapter designed to connect corrugated drainage pipe to smooth-wall drainage systems. It accepts both 3 inch and 4 inch corrugated pipe on the bell end and transitions to a 4 inch spigot outlet for connection into standard drainage fittings. This adapter is commonly installed by plumbers and drainage contractors during site drainage, yard drainage, or storm drain work where corrugated flexible pipe must tie into solid PVC or ABS drainage runs. The dual-size inlet allows a single part to serve two common pipe sizes, reducing the need for separate adapters on the job.

The NDS 1241 is suited for residential and light commercial drainage installations. Typical applications include catch basin outlets, downspout drainage runs, French drain terminations, and subsurface yard drainage systems where corrugated pipe transitions to a rigid pipe network. It is designed for use in non-pressure, gravity-flow drainage applications.

Key Features

• Accepts both 3 inch and 4 inch corrugated pipe on a single bell-end inlet
• 4 inch spigot outlet connects to standard 4 inch drainage fittings
• Universal fit simplifies corrugated-to-smooth-wall transitions
• Designed for gravity-flow, non-pressure drainage applications

Compatibility

Designed as an OEM-style replacement and standard-fit adapter for 3 inch and 4 inch corrugated drainage pipe transitioning to 4 inch spigot drainage fittings in gravity-flow drainage systems.

Installation Notes

Installation is typically performed by a plumber or drainage contractor. Ensure all flow is stopped and the drainage system is clear before making connections. The spigot end should be inserted into a compatible 4 inch drainage fitting using solvent cement or a gasketed coupling per the fitting manufacturer instructions and applicable local plumbing codes. Do not use this adapter in pressurized pipe systems.
