Aco 93871 Pvc Drain Flange Coupling

Product Description

The ACO 93871 is a PVC membrane fitting designed to connect and clamp a CPE (chlorinated polyethylene) flexible membrane to a plain body drain channel using a compression fit. Made from polyvinyl chloride, this flange coupling creates a watertight seal between the membrane and the drain assembly, preventing water infiltration at the transition point. It is commonly installed in below-grade waterproofing and drainage applications where membrane integrity at the drain connection is critical. Licensed plumbers and waterproofing contractors typically handle installation as part of a larger drainage system assembly.

This fitting is used in residential and commercial below-grade drainage installations, including pool decks, planter boxes, balconies, terraces, and wet-area flooring systems where a CPE flexible membrane is incorporated into the waterproofing assembly. It pairs with the ACO plain body channel and is intended for applications where a secure, compression-style membrane clamp is required at the drain flange interface.

Key Features

• PVC construction provides corrosion resistance in wet and chemical-exposure environments
• Compression fit design clamps CPE flexible membrane without fasteners for a secure seal
• Compact profile at 6.46 x 6.46 x 3.21 inches fits standard drain channel footprints
• Designed for use with plain body ACO channel for consistent system compatibility
• Polyvinyl chloride material is suitable for below-grade and surface-drainage installations

Compatibility

Designed for use with the ACO plain body drain channel and CPE flexible membrane systems. No additional specific model compatibility data was provided by the manufacturer for this part.

Installation Notes

Installation is typically performed by a licensed plumber or waterproofing contractor as part of a membrane drainage assembly. Ensure the drain channel is clean and free of debris before seating the flange coupling. The compression fit should be fully engaged around the CPE membrane perimeter before any surrounding substrate is poured or set. Follow applicable IPC and local plumbing code requirements for below-grade drainage connections.
