Description
3" x 2" PVC DWV Increaser-Reducer Eccentric Coupling (H x H)
3" x 2" PVC DWV Increaser-Reducer Eccentric Coupling (H x H) provides an offset transition between different nominal PVC drain, waste, and vent pipe sizes. The eccentric coupling uses hub connections at both ends to receive compatible 3" and 2" PVC DWV pipe.
The 3" x 2" H x H eccentric coupling configuration provides a compact size transition while maintaining an offset centerline between adjoining pipe sizes. Selection should account for both nominal sizes, hub compatibility, eccentric orientation, adjoining pipe, joining requirements, piping alignment, support, and available installation clearance.

Eccentric Coupling Design
The eccentric coupling configuration provides a transition between 3" and 2" compatible PVC DWV piping while maintaining an offset relationship between the two connection centerlines. This configuration is useful where the piping layout requires a non-concentric size transition.
The coupling orientation should be established before permanent joining so the offset corresponds with the intended piping arrangement. Planning the position helps coordinate adjoining pipe, nearby fittings, support, and available working clearance.
Hub Connections
The hub connections receive appropriately sized compatible PVC DWV pipe at both ends of the coupling. Because the fitting connects 3" and 2" nominal sizes, each hub should be matched carefully to the correct adjoining pipe.
The mating pipe and hub surfaces should be prepared using the appropriate PVC DWV joining procedure. Proper insertion, compatible joining materials, correct eccentric orientation, and careful alignment help establish the transition without unnecessary stress on the fitting.
PVC DWV Integration
The PVC DWV construction allows the eccentric coupling to integrate into compatible drain, waste, and vent piping arrangements requiring an offset size transition. Matching the 3" and 2" hub interfaces to the adjoining PVC pipe helps maintain the intended piping configuration.
Application suitability should be evaluated using the requirements of the complete DWV system. Adjoining materials, connection compatibility, joining materials, piping support, slope where applicable, and local installation requirements should all be considered during fitting selection.
Offset Size Transition
A 3" x 2" PVC DWV Increaser-Reducer Eccentric Coupling provides a compact method of transitioning between different compatible pipe sizes without using a concentric centerline. The H x H arrangement accepts compatible PVC DWV pipe at both ends.
Installation planning should consider both nominal sizes, eccentric orientation, pipe alignment, nearby fittings, available clearance, and piping support. Connected piping should align naturally without forcing the coupling to compensate for unrelated offsets.
Installation & Selection Considerations
- Confirm the 3" x 2" sizes.
- Verify the H x H arrangement.
- Check PVC DWV compatibility.
- Confirm the eccentric orientation.
- Align adjoining pipe before assembly.
Our PVC fitting specialists can help review the 3" x 2" sizes, DWV requirements, H x H configuration, adjoining PVC pipe, eccentric orientation, joining requirements, piping alignment, support requirements, and available installation clearance before you order.
Frequently Asked Questions
What is a 3" x 2" PVC DWV Increaser-Reducer Eccentric Coupling used for?
It provides an offset transition between compatible 3" and 2" PVC DWV pipe sizes.
What does H x H mean?
It identifies hub connections at both ends of the fitting.
Why is this coupling called eccentric?
The different connection sizes are arranged with offset centerlines rather than a concentric transition.
What connects to the hub openings?
The hub openings receive appropriately sized compatible PVC DWV pipe.
Does fitting orientation matter?
Yes. The eccentric offset should be positioned according to the intended piping layout.
What should I confirm before ordering?
Confirm the 3" x 2" sizes, H x H arrangement, PVC DWV compatibility, and required eccentric orientation.
Important Ordering & Installation Notes
- Inspect both hubs before use.
- Confirm the 3" x 2" sizes.
- Verify the H x H arrangement.
- Prepare adjoining pipe correctly.
- Set the eccentric orientation before assembly.
