These brass hose barb quick couplers are solid brass fittings designed to connect 5/16″ hose barb to 1/4″ NPT male threads. Supplied as a 2-pack.
Each coupler features a hose barb on one end and male NPT (National Pipe Thread) on the other, creating a tight seal on both hoses and NPT-threaded connections. The barb design grips the inner tube securely, while the NPT thread provides a stronger seal than straight thread alternatives.
Made from high-quality solid brass, these fittings resist abrasion and corrosion, and withstand temperatures up to 100°C. They can handle burst pressures from plastic tubing commonly found in industrial and commercial applications.
Suitable for temperature control circuits, pneumatic systems, vacuum applications, and fluid test apparatus. Also ideal for lubricant and coolant line connections where durability and reliability matter.
All products undergo strict quality inspection before packing and dispatch. If you have concerns with your purchase, contact us for support or a replacement within 90 days.
Check the thread size and barb diameter against your existing hose and connections before ordering to ensure compatibility.
