ProTool M22 14MM to M22 15MM Twist Union Brass

M22 14mm Plug x M22 15mm Plug 

This M22 threaded seal plug converts a 14mm stem to a 15mm stem for a M22 threaded seal coupler system. 

This is commonly used when installing M22 Spray Guns with 14Mm Stems onto a J.Racenstein Wash Sprayer or sprayers from other manufactures such as Sunjoe, AR, Ryobi, or Greenworks that will require a 15mm conversion. 

Consider your connections as there may be a need to purchase another screw coupler to properly connect to your accessory.
