PVC DWV Male Adapter for 2-inch Hub Connections

This Mueller Industries 1WKG6 fitting joins a 2-inch hub to a male NPT thread in drain, waste and vent systems. The Schedule 40 PVC body is coloured white and meets ASTM D1784 cell class 12454 for material quality. It is supplied new and intended for non-pressure plumbing installations.

Capacity and headroom in gravity-flow drainage

The adapter handles standard DWV flow rates through a 2-inch hub without restriction in vent or waste lines. It is not rated for pressure applications, so it must not be used on pressurised supply or pump discharge lines. The maximum service temperature is 140 degrees F, limiting use to cold and warm waste streams only.

Hub-by-MNPT connection type decides fit

The fitting presents a solvent-weld hub on one end and male NPT threads on the other, so the mating pipe and threaded component must match those exact interfaces. No other connection style or pipe diameter is compatible with this model. Verify the system uses 2-inch hub and MNPT before purchasing.

Questions about this item

Will the 2 in Hub x MNPT connection on this Schedule 40 PVC adapter mate with my existing 2 in DWV piping?

Yes, the Hub x MNPT ends are sized for 2 in DWV pipe and Schedule 40 fittings, so it will join directly to matching hub and male-threaded components in your current system.

How can I confirm the joint is leak-free after solvent-welding the hub and threading the MNPT end?

Pressurise the DWV line with a low-pressure air test or run water through the system; no bubbles or drips at the hub or threads indicate the adapter is seated and sealed correctly.

Does the box include solvent cement, thread sealant or any gaskets, or must I buy them separately?

The package contains only the white PVC male adapter; PVC solvent cement, thread sealant tape or paste, and any required gaskets are sold separately.
