Pasco 5822CK Cast Iron to Copper Proseal Transition Coupling for DWV

Pasco 5822CK Cast Iron to Copper Proseal Transition Coupling for DWV

The Pasco 5822CK Proseal Coupling is a cast iron pipe/plastic to copper transition fitting built for rough-in drain-waste-vent connections where dissimilar pipe materials meet behind the wall or under the floor. This coupling lets a plumber or contractor tie cast iron or plastic (DWV) pipe directly into copper tube without cutting in a separate reducing fitting, keeping the transition joint compact and serviceable in tight rough-in spaces. The 5822CK is offered across the family's available sizing, spanning 1-1/2", 2", and 3", so plumbers can match the coupling to the branch or stack size on the job rather than reworking the whole line. As a Proseal-style coupling, it is designed to make a mechanical seal across the material transition, and it ships in a standard order quantity multiple of 24 EA for stocking trucks and supply houses on commercial and residential jobs alike.

Key Features

• Available Sizes: Offered in 1-1/2", 2", and 3" to match common cast iron and plastic DWV branch and stack diameters.
• Transition Fitting: Joins cast iron pipe or plastic DWV pipe to copper tube in a single coupling, eliminating the need for multiple reducing adapters at the transition point.
• Cast Iron Body: Constructed with a cast iron component for durability at the pipe-side connection, matched to the cast iron/plastic pipe run it mates to.
• Copper-Side Connection: Provides a dedicated copper connection point, allowing the fitting to bridge directly to copper tube on the downstream or upstream run.
• Proseal Design: Engineered as a Proseal-type coupling for a mechanical seal at the dissimilar-material joint, simplifying rough-in transitions on DWV lines across all available sizes.
• Stocking-Friendly Packaging: Available with an order quantity multiple of 24 EA and a minimum order quantity of 1 EA, suited to both single-job pickups and bulk truck stock.
• Rough-In Application: Purpose-built for behind-the-wall and under-floor plumbing work, not a finish or decorative fixture component.
