Advanced Drainage Systems 1264WT Hdpe Watertight Tee 12 in

Product Description

The ADVANCED DRAINAGE SYSTEMS 1264WT is a 12-inch HDPE watertight tee fitting designed for use with ADS N-12 dual-wall corrugated pipe systems. This fitting creates a sealed, leak-resistant branch connection in underground storm drainage and stormwater management installations. The watertight seal meets the performance demands of below-grade drainage systems where soil infiltration and exfiltration control are critical. Licensed plumbers, civil contractors, and site utility crews are the primary installers. HDPE construction delivers long-term resistance to corrosion, chemical exposure, and soil loading common in subsurface drainage applications.

This fitting is used in residential, commercial, and municipal stormwater drainage systems where a watertight branch connection is required at a 12-inch mainline. Typical applications include storm sewer laterals, detention system inlets, parking lot drainage networks, and site grading drainage infrastructure. The N-12 system is widely specified in civil and site utility work where dual-wall corrugated HDPE pipe is the approved drainage conduit.

Key Features

• 12-inch nominal diameter HDPE tee for N-12 corrugated pipe systems
• Watertight connection design controls infiltration and exfiltration in below-grade installations
• HDPE material resists corrosion, abrasion, and common soil chemicals
• Compatible with ADS N-12 dual-wall corrugated pipe for mainline branch connections
• Order increment of 1 unit for flexible procurement

Compatibility

Designed for use with ADS N-12 dual-wall corrugated HDPE pipe in 12-inch diameter storm drainage applications.

Installation Notes

Installation is typically performed by licensed plumbers or site utility contractors following local storm drainage codes and ASTM guidelines for HDPE pipe systems. Excavate and bed the trench to the required grade before fitting placement, and ensure pipe ends are clean and free of debris before making the watertight connection. Do not over-deflect the pipe joint or use tools that could distort the HDPE fitting during assembly. Confirm local jurisdiction requirements for watertight storm sewer connections prior to backfill.
