Description
When you’re plumbing hydraulic lines or connecting small pneumatic systems on your equipment, getting the right fitting makes all the difference. This brass hose barb adapter lets you connect a 1/4 inch hose to a 3/8 inch NPT port—perfect for those times when your hose diameter doesn’t match the port size on pumps, valves, or gauges.
What You’re Getting
- Solid brass construction that won’t rust or corrode like steel fittings
- 3/8 inch male NPT threads that seal tight in female ports
- 1/4 inch barbed end holds hose securely without clamps in most applications
- Smooth interior bore maintains good flow through the connection
Built for Real Farm Work
This fitting handles the everyday connections you need around the farm—hydraulic gauge lines, air tool hookups, small pneumatic cylinders, or anywhere you need to step down from a larger threaded port to smaller hose. The brass material stands up to hydraulic fluid, diesel fuel, and most farm chemicals without breaking down.
Made to Last
Brass fittings like this one are the go-to choice for hydraulic work because they’re tough enough for pressure but soft enough that they won’t damage expensive pumps or valves when you’re threading them in. The material resists corrosion better than steel and machines to tighter tolerances than cast iron.
Good to Know
Thread the NPT end in finger-tight first, then use a wrench to snug it up—don’t overtighten or you’ll strip the threads. For the hose end, warm the hose in hot water for easier installation, and most 1/4 inch hoses will seal fine without a clamp if the barb is sized right.
