Polypropylene Cam & Groove Adapter, 2 Inch Dust Plug

Both standards are covered. The 2-inch polypropylene dust plug is built to interchange with any cam and groove product made to MIL-C-27487F or DIN282 specs, so you can drop it into either system without worrying about fit. That interchangeability covers sizes from half-inch through 4-inch, and the pressure rating across that range runs up to 150 PSI.
