This is a solid little fitting for custom fuel, oil, or coolant lines.

It's a 4AN male flare tee, made from 6061-T6 aluminum with a black anodized finish - so it's lightweight, strong, and resistant to corrosion.

The 37-degree flare sealing angle is standard for AN fittings and ensures a tight, leak-free seal under pressure.

You can use it to split a single line into two, or combine two lines into one, in systems handling fuel (including alcohol-based), oil, water, or even air.

The black finish looks clean and hides stains.

Just remember, AN fittings require proper flared tubing or compatible hose ends to work correctly - this is just the tee piece itself.

Professional installation is a good idea if you're not experienced with fluid line systems, because getting the flare right is crucial.

No instructions come with it, so you need to know what you're doing.

But if you're building or repairing a performance car, bike, or industrial setup, this is a reliable, well-made fitting that'll do the job.
