## Before you buy

- Fit language needs careful interpretation: the title specifies 2-inch copper DWV pipe, while the installation claim describes 2-inch Schedule 40 DWV pipe, and the broader compatibility claim mentions 15-inch pipe and says copper use requires replacing the gasket. Confirm the intended pipe and gasket configuration before ordering. The listing does not establish that the drain body or caulking nut is included.

## In the box

- Rubber caulking gasket (Included)

## A good fit for

- Replacing the caulking gasket in a compatible Oatey no-calk shower drain.
- Buyers matching a 2-inch DWV pipe and existing drain hardware.

## Less suited to

- Anyone needing a complete shower-drain assembly rather than a replacement gasket.
- Installations where pipe size or material has not been matched to the gasket and drain instructions.

## Customer feedback

Aggregate customer ratings lean positive overall, with most ratings in the top two star categories, but a notable share are lower. Without written feedback, these figures do not show what customers liked or what prompted lower ratings. For a small replacement part, confirm the pipe and drain match rather than treating the ratings as evidence of fit for a particular installation.
