This is a specific industrial adapter for hydraulic or pneumatic systems.

If you're working on machinery, agricultural equipment, or industrial setups, you might need this.

One end has a 3/4-16 male NPT (National Pipe Taper) thread with a JIC (Joint Industry Council) 37-degree flared seat.

The other end has a 1/2-14 male NPTF (National Pipe Taper Fuel) thread.

Basically, it lets you connect a female JIC-flared hose or fitting to a female NPTF threaded port, or vice-versa, while stepping down the size from 3/4 inch to 1/2 inch.

It's made from tough steel with a zinc plating for corrosion resistance, so it can handle the pressure and harsh environments.

Dixon is a well-known, reliable brand in the fluid power industry.

Part number is 2404-8-8.

If you know you need this specific fitting to fix a leak or build a line, this is the genuine part.

Not for beginners – this is for pros who know their thread types.
