Aluminum Cam & Groove Adapter, 1 Inch Dust Cap

Meets the A-A-59326 interchangeability standard, so it will couple with cam and groove products from other manufacturers built to that same spec. The one thing worth knowing is that half-inch and eight-inch sizes generally don't interchange across brands since no formal standard covers those sizes. The one-inch size you're looking at falls right in the middle of the range where cross-brand compatibility holds up.

For keeping dirt and debris out between uses, this is a 1 inch cam and groove dust cap with a Buna-N seal to help close it off.

Interchangeability shouldn't be a problem. This dust cap is made to the A-A-59326 standard, so it'll fit with any cam and groove stuff built to that spec.
