By Claire WhitakerUpdated November 2026
Choosing the right plumbers putty for kitchen sink drain work comes down to a few practical questions: will it stay pliable long enough to seal the flange, will it resist hardening if you leave the can open, and will it clean up without leaving residue on your sink? This guide compares six widely sold putties with those questions in mind. We looked at product specifications stated by manufacturers, brand reputation for plumbing supplies, and the patterns owners tend to mention in their feedback, such as ease of kneading, how well the putty holds a seal under a strainer, and whether it stains porcelain or stainless steel.

Buying Guide
Oil-based versus oil-free formulas
Traditional plumbers putty is oil-based, while some newer formulas are described as oil-free. Oil-based putty can stain some plastics, acrylic and certain sink finishes over time, so many people prefer oil-free options for kitchen sinks. Check the label before you buy, especially if you have a composite or painted sink.
Good picks for this: Oatey 31177 Plumbers Putty, 9 oz; Harvey’s WM Harvey 043010 Stainless Plumbers Putty, 14 oz
Non-hardening performance
Putty that hardens in the can or on the flange will not seal well. Look for wording such as non-hardening, stay-soft or does not crumble. Keep the lid tightly closed and store the container out of direct heat.
Good picks for this: Harvey’s WM Harvey 043010 Stainless Plumbers Putty, 14 oz; Stay Soft Plumbers Putty, 7 oz
Container size and quantity
A single drain flange typically needs only a small amount, often a rope roughly the thickness of a pencil and the length of the flange circumference. A 7 oz or 9 oz size covers most single-sink jobs, while a 14 oz tub is useful if you expect to reseal several fittings or keep putty on hand for future repairs.
Good picks for this: Stay Soft Plumbers Putty, 7 oz; Oatey Plumber’s Putty, 14 oz Tub, Sta Put Ultra
Compatibility with your sink material
Stainless steel, porcelain, cast iron and composite sinks all respond differently to residue and solvents. Test a small spot on an inconspicuous area and wipe with a damp cloth. Avoid harsh solvents on stainless, and use mild soap if you see any discoloration after removal.

Stickiness and holding strength
A strainer or drain flange needs a seal that resists water pressure without squeezing out. Putty that is too soft can slump, while very stiff putty may not compress evenly. Medium-firm formulas tend to press into the flange groove best, so knead the putty until it is smooth and pliable before rolling it.
Good picks for this: Oatey 25171 Sta Put Ultra Plumbers Putty, 14 oz; Oatey Plumber’s Putty, 14 oz Tub, Sta Put Ultra
Ease of use and cleanup
Putty that is easy to knead and wipes clean with a dry cloth will save time. Form it into a rope, press it around the flange underside, install the strainer, and remove excess squeeze-out with a plastic scraper before it sets. Clean any remaining residue with a little mild dish soap.
Good picks for this: Plumbers Putty Roll; Oatey 31177 Plumbers Putty, 9 oz
Storage and shelf life
Keep putty sealed and away from heat. A tightly closed tub or wrapped roll stays usable far longer than an open container. If the putty becomes dry or crumbly, discard it and buy fresh; attempting to revive it often leads to a poor seal.

FAQ
What is plumbers putty used for under a kitchen sink?
Plumbers putty creates a watertight seal between the sink basin and the drain flange, and it is also used around some strainers and fixtures. It fills small gaps so water does not leak into the cabinet below.
Can I use plumbers putty on a stainless steel sink?
Yes, but choose a formula labeled for stainless or non-staining use, and remove any residue promptly. Test on a small area first if you are unsure how your finish reacts.
How much plumbers putty do I need for a kitchen sink drain?
For a standard drain flange, a rope about the thickness of a pencil and long enough to go around the flange is usually enough. Using too much can squeeze out and create cleanup work, so start small and add more only if needed.
Does plumbers putty harden over time?
Some formulas can dry out or harden, especially if the container is left open. Non-hardening or stay-soft products are designed to resist this, but all putty should be stored tightly sealed.
Is oil-free plumbers putty better for kitchen sinks?
Oil-free formulas are often preferred for sinks with sensitive finishes because they are less likely to cause staining. Always check the label and confirm compatibility with your sink material.
How do I remove old plumbers putty from a sink drain?
Warm the old putty with a hair dryer to soften it, then scrape it away with a plastic putty knife. Avoid metal tools on finished surfaces. If residue remains, a mild solvent recommended for your sink material can help, but follow the product directions carefully.

For most kitchen sink drain seals, the Oatey 31177 Plumbers Putty, 9 oz is a dependable starting point, particularly for porcelain and enameled sinks.
