3" PVC DWV 90° Hub Elbow
The Mueller Industries 1WKA4 is a Schedule 40 PVC drain component designed for DWV systems. It provides a 90 degree change of direction using a hub connection. The fitting is white and rated for a maximum temperature of 140 degrees F. It meets ASTM D1784 cell class 12454 standards.
Suitable for non-pressure drainage revisions
This elbow suits installers modifying or extending 3 inch PVC drain waste vent lines where a sharp turn is required. It is not for buyers who need a pressure-rated fitting or a solvent-weld spigot connection. The hub design requires a matching pipe end for assembly. Plumbers needing a different angle or size should select another fitting.
Hub connection simplifies solvent welding
The hub socket accepts standard 3 inch PVC pipe directly, removing the need for a separate coupling. This reduces joint count and potential leak paths in the drainage run. The Schedule 40 wall thickness matches common DWV pipe for consistent fit. No additional seals, lubricant or brackets are included with the fitting.

Questions about this item
What size and schedule of PVC pipe does the 3-inch hub on this 1WKA4 elbow accept?
The hub is sized for 3-inch Schedule 40 PVC pipe, matching the fitting's schedule class.
Can this 90-degree DWV elbow handle the 140-degree maximum temperature rating when connected to older ABS drain lines?
The fitting is rated to 140 degrees Fahrenheit, but it is PVC and requires a proper transition coupling to join ABS pipe.
How can I confirm the 1WKA4 elbow meets the ASTM D1784 cell class 12454 standard after installation?
Look for the ASTM D1784 and cell class 12454 markings moulded onto the white PVC body of the fitting.
