How to Measure Your Faucet Thread

1. Step 1: Determine whether your faucet aerator uses a male or female thread. Female threads are on the inside of the fitting; male threads are on the outside.
2. Step 2: Using a ruler or caliper, measure the inner diameter of the female thread opening. This set is designed for a 21.5mm (M22) female thread.
3. Step 3: Confirm your measurement matches 21.5mm, then add to cart. If you need a different size, contact us — many sizes are available.

Frequently Asked Questions

Q: What faucet size does this 21.5mm female thread rubber gasket fit?

A: This gasket is specifically designed for M22 female-thread faucet aerators with a 21.5mm inner diameter. It fits the inside of a standard female-threaded aerator housing, creating a secure, hermetic seal between the aerator adaptor and the pipe hose. If you are unsure, measure the inner diameter of your fitting before ordering.

Q: Can these rubber rings be used on both bathroom and kitchen faucets?

A: Yes! As long as your faucet aerator uses a 21.5mm (M22) female thread, these rubber sealing rings work on bathroom taps, kitchen faucets, and most standard household pipe hose connections. They are a universal replacement gasket for this thread size.

Q: How many gaskets are included, and why do I need extras?

A: Each pack contains 5 rubber gasket rings. Having multiple rings on hand is ideal for multi-faucet households or as backup replacements — rubber seals can wear over time, and having spares means you can swap in a fresh seal quickly without placing another order.

Q: Is installation easy for someone with no plumbing experience?

A: Absolutely. Installation requires no special tools. Simply remove the old or worn gasket from your aerator adaptor, seat the new rubber ring into the groove or housing, and thread the aerator back onto your faucet. The flexible rubber compresses to form a tight seal as you tighten the fitting by hand.
