Measuring a faucet aerator correctly is essential for finding the right replacement. Based on the type of aerator you have, you will measure either its inner or outer diameter.
Understanding Faucet Aerator Sizes
Faucet aerators come in two main types: male and female. This classification refers to the threading on the aerator itself and the faucet spout.
- Male Aerator: Has threads on the outside. It screws into the faucet spout.
- Female Aerator: Has threads on the inside. The faucet spout screws into it.
Knowing the type is crucial because it dictates how you measure it.
The Correct Way to Measure Your Aerator
The reference states the specific method for measuring based on the aerator type:
- To measure Female aerator size, you need to measure the inner diameter of the aerator.
- To measure Male aerator, you need to measure the outer diameter of the aerator.
This method ensures you are measuring the critical dimension where the threads connect to the spout.
Step-by-Step Measurement
- Remove the Aerator: Carefully unscrew the aerator from your faucet spout. You might need a wrench or an aerator removal tool if it's tight or has hidden grooves.
- Identify the Type: Look at the threading on the aerator.
- If the threads are on the outside edge of the aerator, it's male.
- If the threads are on the inside of the aerator, it's female.
- Measure: Use a ruler, tape measure, or preferably a caliper for accuracy.
- For a Female Aerator: Measure the distance straight across the inside opening, from one threaded edge to the opposite threaded edge. This is the inner diameter.
- For a Male Aerator: Measure the distance straight across the outside edge, from the outermost point of the threads on one side to the outermost point on the opposite side. This is the outer diameter.
Measurement Summary
| Aerator Type | Threading Location | Measurement Method | Dimension Measured |
|---|---|---|---|
| Female | Inside | Measure across the inside opening | Inner Diameter |
| Male | Outside | Measure across the outside threads | Outer Diameter |
Note: Aerator sizes are typically measured in millimeters or standard pipe thread sizes (like 15/16", 55/64", 13/16"). Your measurement will help you determine the correct size.
Practical Tips for Measuring
- Use Calipers: Digital or dial calipers provide the most accurate measurement.
- Measure Carefully: Ensure you are measuring straight across the diameter, not at an angle.
- Multiple Measurements: Measure in a couple of different spots to ensure consistency.
- Compare to Coins: If you don't have precise tools, you can sometimes get a rough idea by comparing the aerator's diameter to common coin sizes, although this is less accurate than measuring.
By following these steps and measuring the correct diameter based on whether the aerator is male or female, you can accurately determine its size for replacement.
