Vibrant Brass Olive Inserts 5/16in - Pack of 5

When you're working with adapter fittings that have a straight thread and need to seal a port that can't take an O-ring, these Vibrant brass olive inserts are what you'll want. They're specifically made for use with aluminum hardline tubing, giving you a reliable seal in those trickier situations.

This pack comes with five 5/16-inch inserts, all made from brass. Brass is a good choice here because it's durable and won't corrode easily, which is important for maintaining a good seal over time. They're designed to work well with Vibrant Performance Metric Adapter Fittings, ensuring a good match if you're using their system.
