ACDelco GM Genuine Parts 12559760 Power Brake Booster Vacuum Hose Connector

This part feels like dense, quality plastic. I DO recommend this vacuum hose connector. It’s the cheapest solution for replacing the old OEM connectors that infamously get brittle over time (it’s the middle part in the photo attached).It didn’t fit my car though… I have a 2000 Mercedes CLK and was hoping this would work. Unfortunately, the hose side is too big, so I ended up 3D printing my own hose connector as an interim solution until the real part arrives from overseas. It holds up just fine (photo attached)
