The best faucet washer is the one that matches the valve you are repairing. Danco 88569, 88573 and 88586 are three useful replacement packs to compare: two flat profiles and one beveled profile, each in a different size. Choose by the existing part and the faucet maker’s requirements, rather than treating these as interchangeable upgrades.
This guide covers rubber washers fitted to compatible faucet stems. Check the faucet’s repair instructions before ordering; a drip alone does not identify the failed component. We compared documented dimensions, profile and pack contents, without hands-on testing or a durability ranking.
Danco’s product pages currently mark all three packs as unavailable. Use these manufacturer links to check specifications, and confirm current stock with a retailer before planning the repair; that status does not establish that the models are discontinued.

Danco 88569: a match for 00 flat washers
Danco 88569 00 Flat Faucet Washers, 10-Pack
As an Amazon Associate we earn from qualifying purchases.
Danco specifies a flat rubber washer with a 0.5-inch outside diameter and a 0.19-inch center opening. The pack contains ten washers. It is a sensible first check when the removed part is a small flat washer and the faucet’s specified replacement is trade size 00. Check Danco’s 88569 specifications.
- Pros: Exact inner and outer dimensions make this pack straightforward to compare with the required part; ten identical washers provide spares.
- Cons: One size and one profile limit its usefulness if you have several different faucets. It should not be substituted for a beveled washer solely because the diameter looks close.
Danco 88573: a larger flat profile in trade size 1/4L
The 88573 is a ten-pack of flat rubber washers with a specified 19/32-inch outside diameter. Danco lists the center opening as 0.2 inch. Compare those measurements with the required part: the “1/4L” name is a trade designation, not a literal quarter-inch outside diameter. Check Danco’s 88573 specifications.
- Pros: A clearly identified size for a matching flat-washer repair, with multiple spares in the same pack.
- Cons: It is larger than the 00 option, so the two packs cannot be selected on appearance alone. A worn or distorted sample needs checking against the faucet’s specified part.
Danco 88586: a beveled option with a 3/4-inch diameter
The 88586 uses a tapered rubber profile and comes with ten washers. Its trade size is 1/2, while the actual outside diameter is 3/4 inch. Consider it only when your faucet calls for that beveled shape and size; a bevel is not a universal improvement over a flat seal. Check Danco’s 88586 specifications.
- Pros: Provides a defined beveled replacement for an appropriate stem, with the actual diameter stated separately from the trade size.
- Cons: The 1/2 trade-size label can be mistaken for the outside diameter. Confirm the full fit, including the center opening and thickness, before buying.
How to choose the right faucet washer
Start with the faucet model or the old stem. Keep the removed washer and retaining screw together, and compare the required profile, outside diameter, center opening and thickness with the replacement. If the old washer is crushed or badly worn, use the maker’s parts information or have a plumbing supplier identify the stem rather than relying on that damaged sample alone.
Check the leak’s location before assuming a washer will fix it. Danco’s stem-repair guidance distinguishes water around the handle from a drip at the spout and explains that a worn stem washer may need attention alongside the faucet seat. Use the instructions for your exact faucet; these packs do not establish compatibility with every valve or cartridge.
Turn off the water supply before disassembling the faucet. If the shutoff will not isolate the water, stop and arrange the appropriate repair first. Once reassembled according to the faucet’s instructions, restore the supply and check for leakage. Avoid forcing a mismatched part into place.
Buy an exact-size pack once the repair is identified. An assortment may be convenient for several known faucet types, but unused sizes are not a benefit for a single repair. Keep any spares labeled with the model number and size so a future replacement can be checked again.
Frequently asked questions
Are faucet washers universal?
No universal fit is established by these packs. Their dimensions and profiles differ, so match the replacement to the faucet’s specified part and stem.
Does 1/2 trade size mean a half-inch outside diameter?
Not for Danco 88586: its 1/2 trade-size washer has a 3/4-inch outside diameter. Use the published dimensions as well as the trade designation.
Should I choose a flat or beveled washer?
Use the profile required by the faucet. Danco identifies 88569 and 88573 as flat washers and 88586 as beveled; shape is a fit requirement, not a general quality ranking.
Will a new washer always stop a dripping faucet?
No. The stem, seat or another component may need attention. Identify the leak and inspect the relevant parts before buying a pack solely on the assumption that the washer is at fault.
Which pack should I buy first?
Buy the pack that matches the specified repair: 88569 for 00 flat, 88573 for 1/4L flat, or 88586 for 1/2 trade-size beveled. If the fit remains uncertain, have the stem identified before ordering.
Our recommendation
For this repair, exact fit matters more than a best-overall label. Use the comparison to identify a matching pack, then check the faucet’s parts diagram or get the old stem matched. That gives each of these washers a useful role without promising that any one pack fixes every leak.
