A 100-pack of woven stainless steel mesh screens, 5/8 in (15.8 mm) across. These are the small round filter discs that sit in front of anything you do not want grit, scale flakes, rust or debris getting into: faucet aerators, appliance inlet valves, fuel pickups, condensate lines, small pumps and funnels.

Stainless is the reason to keep a pack around. It does not rust, it does not soften in fuel or solvent, and it holds its shape when you press it into a housing. Pull it, rinse it, put it back.

Check the size before you order. 5/8 in (15.8 mm) is the small end of the range. It is the right neighbourhood for aerator housings, appliance inlet screens and small-engine fuel fittings. It is far too small for a kitchen, bath or tub drain, which runs 1-1/4 in to 1-1/2 in.

Why the stainless ones

No rust. Unlike plain steel or plated screens, these do not bloom orange the first time they sit wet.
Fuel and solvent safe. Gasoline, diesel, mineral spirits, lacquer thinner: none of it softens or swells stainless the way it does nylon.
Reusable. Rinse, blow out or brush and refit. Replace only when the weave is torn or packed solid.
Holds its shape. Stiff enough to press into a recessed housing with a fingertip or the end of a socket, thin enough to cup or fold.
Trim to fit. Ordinary tin snips take them down to a smaller diameter in seconds.
100 to a pack. Cheap enough to leave a strip in the van, the mower shed and the plumbing bag instead of hunting for the one you had.

Will it fit?

Measure the opening, not the fitting. Pull the old screen out, lay it on a rule and check it against 5/8 in (15.8 mm). If the old one is smaller, trim one of these down with snips and deburr the edge. If the old one is bigger, this is not your part.

The one place these definitely do not go is a sink, tub or shower drain. Those openings are 1-1/4 in to 1-1/2 in and need a proper drain strainer, not a mesh disc.

How to fit one

Shut it down. Close the supply valve, or drain and isolate the fuel side, before you open anything.
Open the housing. Unthread the aerator, hose fitting, valve cap or fuel inlet. Keep the washer and any spacer in order.
Clean it out. Pull the old screen and flush the grit and scale that put it there in the first place.
Seat the new screen. Drop it flat, or cup it slightly with a fingertip or the end of a socket if the housing is recessed.
Reassemble and flush. Snug it up, turn the supply back on and run it for a minute to clear anything you loosened.

Frequently asked questions

What size are they exactly?

5/8 in across, which is 15.8 mm. Flat round discs.

Will they fit my sink drain?

No. Sink, tub and shower drains are 1-1/4 in to 1-1/2 in. These are less than half that. They are inlet and aerator screens, not drain strainers.

Will they fit my faucet aerator?

Many standard aerator housings, yes, but measure rather than guess. Unthread the aerator, take the old screen out and check it against a rule. If yours is smaller, trim one of these to match.

Can I cut them down?

Yes. Tin snips or heavy scissors, then run a file or a fingernail over the edge so a burr does not catch a washer.

Are they safe in fuel?

Stainless does not soften, swell or dissolve in gasoline, diesel or common shop solvents, which is exactly why small-engine fuel screens are made of it.

How fine is the mesh?

It is a general-purpose fine weave: fine enough to hold back grit, scale flakes and sediment, coarse enough to keep flowing. It is not a micron-rated filter media, so if your job calls for a specified rating, this is not that part.

Can I reuse them?

Yes. Rinse, blow out or brush them and put them back. Replace when the weave tears or packs solid.

Why 100 in a pack?

Because they cost pennies each, they live in the bottom of a bag, and the one time you need one you will not have it. A hundred lasts most people years.
