Kitchen Sink & Drain Strainer Basket is used primarily for catching food scraps at the kitchen sink outlet while letting water drain freely. This page lists the industries and assemblies where it is specified, the selection criteria that matter for each application, handling and installation practice, and the cases where a different mesh, screen or filter type is the correct choice. It is supplied to ASME A112.18.2.
Typical Applications for Kitchen Sink & Drain Strainer Basket
Where Kitchen Sink & Drain Strainer Basket is specified and bought:
- Sink manufacturers: basket strainers supplied with stainless sinks.
- Plumbing wholesale: standard 114 mm basket replacements.
- Bathroom fittings: flat hair-catcher inserts.
- Commercial kitchens: floor drain inserts.
How to Specify Kitchen Sink & Drain Strainer Basket for Your Application
- Drain size: Kitchen sinks use a 3.5 in (89 mm) drain with a 114 mm flange basket.
- Hole size: 2 mm holds rice and scraps; 1.5 mm for bathrooms.
- Stopper: Choose a basket with a sealing stopper if the sink must hold water.
- Standard: Quote ASME A112.18.2 and the size designation from the table on the product page, plus any value you changed in the technical drawing.
Handling & Installation Practice
- Empty the basket into compost or trash, not the sink, after each wash-up.
- Clean the stopper seal monthly so it keeps sealing.
Common Selection Mistakes with Kitchen Sink & Drain Strainer Basket
- Buying a basket by the sink flange instead of the drain body diameter.
- Choosing holes so fine that grease blinds them.
Where Kitchen Sink & Drain Strainer Basket Is Not the Right Choice
Not a grease trap — fats still need separate interception in commercial kitchens.
