Vibrant 1/4in Brass Olive Inserts - 5pk

These Vibrant brass olive inserts are a neat little part for when you're working with aluminum hardline tubing and need to seal a port that doesn't have a place for a standard O-ring gasket. They're specifically made to work with Vibrant Performance Metric Adapter Fittings, giving you a solid seal in those tricky spots. The brass construction means they're well-built for the job.

You get a pack of five 1/4-inch inserts, each designed for a 0.25-inch outer diameter tube. They're a straightforward solution for fabricating custom lines or adapting different fitting types where a reliable seal is key. Just slide one onto your tubing before connecting your fitting, and it compresses to create that seal.
