The M22 14mm X 15mm MTM Hydro twisted sealing cap is designed to convert a 14mm rod into a 15mm rod of a twisted joint coupler. This is commonly used when installing MTM Hydro guns on Sunjoe, AR, Ryobi or Greenworks pressure washers that require 15mm conversion.
14 mm and 15 mm refer to the inside diameter (ID) of this M22 connector.
When installing the 15mm side in a 15mm coupler, it will be tight, but it will fit!.
