Measure the outer diameter of your aerator housing before ordering. Type A is typically suited for larger-diameter aerators, while Types B, C, and D cover progressively smaller or differently profiled fittings. If you are unsure, the 3-piece set gives you the best chance of finding the right fit without a separate purchase.

The key is designed with a grip profile that contacts the aerator housing rather than the decorative faucet body. For extra protection on polished finishes, wrap the aerator rim with a thin cloth before applying the wrench.

Yes. The key profiles are compatible with both external-thread (male) aerators that screw onto the faucet spout and internal-thread (female) aerators that fit inside the spout opening. Check your faucet type before selecting a variant.

For heavily corroded aerators, apply a penetrating lubricant and allow it to soak for 10–15 minutes before using the wrench. The key's snug fit on the aerator housing maximizes torque transfer. Avoid using excessive force, which can crack plastic aerator bodies.

This universal tap spanner is designed to fit aerators from most major residential faucet brands that use standard thread sizes. Compatibility depends on the aerator's outer diameter and thread profile. Contact us to confirm fit for less common or commercial-grade faucet models.

The quantity variants (1 pcs vs. 3 pcs) refer to the number of keys of the selected type included in the pack. If you need multiple key types, select individual variants or contact us for bundle options.

Yes, the wrench works for both removal and installation. When reinstalling, hand-tighten first, then use the key for a final snug turn — avoid overtightening, which can damage the aerator's rubber washer or thread.
