Fragola -6AN Bulkhead Tee-On The Run

This is a Fragola -6AN bulkhead tee fitting, often called an "on the run" tee. It's designed to let you tap into an existing line to add a new port without cutting the main hose. This is super handy when you need to add a gauge, a sensor, or a secondary line to a system that's already plumbed.

The "on the run" design means you can install it directly onto a hose that's already in place. You'll typically use this for fuel systems, oil lines, or vacuum setups where you need to branch off a feed. The -6AN size is a common standard in performance and custom automotive applications, making it easy to find compatible hoses and adapters.
