Ads 1515aa 15 Inch Dual Wall Split External Coupling

Product Description

The ADS 1515aa is a 15-inch dual wall split external coupling designed for joining sections of dual wall corrugated pipe in drainage and stormwater management systems. Constructed from high-density polyethylene (HDPE), this fitting delivers reliable performance in below-grade and surface drainage installations. The split external design allows the coupling to be installed around existing pipe runs without requiring pipe ends to be threaded or slipped, making field repairs and connections more straightforward for drainage contractors and civil construction crews.

This coupling is suited for residential, commercial, and municipal stormwater drainage applications where 15-inch dual wall corrugated HDPE pipe is specified. It is commonly installed in trench drain systems, culvert connections, and underground stormwater conveyance runs. The split configuration is particularly useful in retrofit or repair scenarios where access to a free pipe end is limited.

Key Features

• Split external design allows installation without access to a free pipe end
• HDPE construction resists corrosion, chemicals, and soil abrasion
• Sized for 15-inch dual wall corrugated pipe
• Suitable for below-grade stormwater and drainage applications
• Lightweight compared to concrete or metal alternatives, reducing handling effort on site

Compatibility

Designed as an OEM-style external coupling for 15-inch dual wall corrugated HDPE drainage pipe systems.

Installation Notes

Installation is typically performed by drainage contractors or plumbers working on stormwater conveyance systems. Ensure the pipe exterior is clean and free of debris before seating the coupling. Follow local building and stormwater codes, and verify trench bedding and backfill requirements before burying the fitting. Do not exceed the pipe and fitting manufacturer's rated load and depth-of-cover specifications for the installation conditions.
