Part Number Decoder

Alicat Part Number Decoder

 

There are many ways to customize your Alicat, but added options can sometimes make your part number look like alphabet soup. We’ve compiled the listings below to help you decipher the various elements of your Alicat part number.

Most Alicat part numbers consist of a top-level part number and a group of adder codes. Top-level part number elements are separated by hyphens (-), and adder codes are separated by commas (,). A forward slash (/) separates these two groups of your Alicat part number.

Top level elements appear before the forward slash (/) in the Alicat part number, as in the example below.
