Best felt stem washers for bathtub faucets

Top pick: the STARTIST 100-pack of white felt stem washers. A tub faucet's stem washer is a wear part, so a bulk bag in a common size means you can redo a drip now and still have spares for the next one — and felt is the right material for the friction seat on a stem.

Who the others suit:

• Ferree's A80–A90 felt valve washers — buy by exact size when you've measured your stem; each size is sold separately, so match the outside diameter, inside diameter and thickness to the old washer.
• Tnarru universal set — a mixed-size grab bag if you don't know the size yet.
• Woodford 50252 — a direct replacement for Woodford outdoor/tub-style faucets.
• Lasco assortment — rubber flat washers and screws, for the seat rather than the stem.

Tip: take the old washer to the store or measure it with calipers — felt stem washers are sized by OD/ID/thickness, and a loose fit will drip again.
