Sioux Chief Dishwasher Discharge Tube with Washer, 1-1/4" OD x 7/8" ID
The Sioux Chief Dishwasher Discharge Tube with Washer is rough-in tubing sized specifically for dishwasher drain connections, featuring a 1-1/4" outside diameter (OD) and a 7/8" inside diameter (ID). It is supplied with a washer to help seal the connection at the drain fitting, so the tube and its hardware arrive together as one part number instead of two separate purchases. This tubing is intended for behind-the-cabinet and under-sink dishwasher discharge routing during new construction, remodel rough-in, or repair work, not as a finished or decorative component that a homeowner would see once the installation is complete. Plumbers and contractors use this class of dishwasher discharge tubing to connect the dishwasher's drain outlet to the branch drain, air gap, or garbage disposal inlet depending on the layout of the job.
Key Features
- Outside Diameter: 1-1/4" OD, sized to seat correctly in dishwasher discharge tube connections and clamp fittings.
- Inside Diameter: 7/8" ID, matched to the dishwasher drain hose fitting to maintain the discharge line's flow path.
- Included Washer: ships with a washer to help seal the connection at the fitting, reducing the need to source a separate sealing washer on the job.
- Product Type: classified by the manufacturer as tubing for dishwasher discharge applications rather than general-purpose pipe.
- Single-Part Convenience: tube and washer are supplied together, which keeps the rough-in parts list simpler for a dishwasher hookup.

Why Sioux Chief?
Sioux Chief manufactures rough-in plumbing components for professional installation, including this dishwasher discharge tube that is sized to the drain connection and supplied with a washer for the fitting seal.
