George ★★★★★ Oct 22, 2026

I was pleasantly surprised by the anodized matte black finish—it looks much more premium than I expected for a small adapter. The 1/8 inch Venturi port is a nice bonus that gave me extra routing flexibility with my fuel system. It seated perfectly on the M12 port with no leaks right from the start.

The anodized matte black finish blends right in with my fuel setup, and the 1/8 inch Venturi port is a lifesaver for adding a vacuum line. Fit the M12 port perfectly with no leaks.

This little 90-degree fitting solved my clearance issue perfectly — the Venturi port is a nice bonus for future projects. The matte black anodized finish looks great and seems durable. Really clean way to adapt a metric M12 port to a standard 3/8 barb.
