The size is quite different for male and female threads. The standard size is 55/64″-27 for females and 15/16″-27 for males. There are some exceptions regarding the sizes as well.

To determine the faucet size:

  • First, remove any type of attachment to the faucet. They can hinder the fitting process.
  • Then, measure the diameter of the sink. The measurement process will vary for male and female threads. For male threads, measure the diameter from the outside. On the contrary, female threads measure the diameter from the inside.

It’s critical to follow this measurement rule. Because the thread sizes of the faucet and its adapter will differ. One will be male and the other will be female.

Let’s say you’ve measured a male thread for the faucet. Conveniently, the same measurement will be equivalent to the female thread of the adapter.

Remember, doing the measuring correctly is a must. Incorrect measurements often lead to mis adjustments of the adapters. Even the top of the line portable dishwashers suffer from this problem.

Determining the thread size is pretty simple. All you have to do is to observe the position of the thread. If the thread is located outside of the faucet, then it’s a male one. In reverse, if it is located inside, it is a female one.
