Product Description

The ADVANCED DRAINAGE SYSTEMS 4P2615+FIT is a 4-inch OneFit Inserta Tee designed for use in corrugated drainage pipe systems where a branch connection must be made into an existing mainline pipe of 15 inches or larger. The Inserta Tee design allows installers to create a tee fitting without cutting the mainline pipe all the way through — the barbed insert locks into a hole made in the host pipe, creating a secure, watertight branch outlet. This fitting is commonly installed by drainage contractors, civil crews, and plumbing professionals working on stormwater, site drainage, and subsurface drainage applications.

The 4P2615+FIT is suited for residential and commercial drainage installations where a 4-inch lateral needs to branch off a larger mainline corrugated pipe of 15 inches or greater diameter. Typical applications include yard drainage systems, roadside culvert tie-ins, and subsurface stormwater management. The OneFit design accommodates a range of host pipe wall profiles, reducing the need to stock multiple fitting sizes for different pipe schedules on the same job site.

Key Features

• 4-inch branch outlet for connection to standard 4-inch corrugated or compatible drainage pipe
• Compatible with host mainline pipes 15 inches and larger in diameter
• Inserta Tee design installs through a single hole in the host pipe without full pipe separation
• OneFit profile adapts to varying corrugated pipe wall geometries
• Reduces labor time compared to traditional saddle tee or cut-in tee methods

Compatibility

Designed for use as a branch fitting on corrugated drainage mainline pipe of 15 inches or larger diameter. Specific host pipe compatibility should be verified against ADVANCED DRAINAGE SYSTEMS installation guidelines for the OneFit Inserta Tee product line.

Installation Notes

Installation is typically performed by drainage contractors or plumbing professionals familiar with corrugated HDPE pipe systems. A hole saw of the appropriate diameter must be used to cut the entry point in the host pipe before inserting the fitting. Ensure the host pipe is depressurized and the trench is dewatered before beginning work. Follow local plumbing and stormwater codes for burial depth, bedding material, and backfill compaction requirements.
