1/2" NPT x 1/2" Barb, Brass

This brass fitting from Goodyear Rubber Products transitions a 1/2-inch NPT threaded connection to a 1/2-inch hose barb, giving you a secure way to attach flexible tubing or hose to threaded plumbing. The combination of durable brass and a barbed end makes it a practical, long-lasting connector for drain lines, supply runs, and accessory hookups throughout water treatment and general plumbing systems.

The fitting works in two parts: the NPT side threads into a fitting, valve, or port, while the barbed side slips into flexible hose and is typically secured with a clamp for a tight, leak-resistant grip. The ridges of the barb dig gently into the hose interior so that, once clamped, the connection resists pulling loose under pressure. This kind of adapter is invaluable any time you need to transition from rigid threaded plumbing to flexible tubing, a frequent requirement when routing softener or filter drain water to a standpipe, floor drain, or sump.

• Brand: Goodyear Rubber Products
• Connection: 1/2-inch NPT (male thread) to 1/2-inch hose barb
• Material: brass for strength and corrosion resistance
• Use with flexible hose secured by a clamp
• Ideal for drain lines and accessory tubing connections
• Suitable for potable and drain applications

Brass construction provides reliable performance and resists the corrosion that can plague lesser materials in wet, continuous-duty service. For the best results, match your hose inner diameter to the 1/2-inch barb so the fit is snug before clamping, and choose a clamp rated for your hose and pressure. A small amount of effort selecting the right hose and clamp pays off in a connection that stays put and stays dry.

Compact, versatile, and easy to install, this NPT-to-barb adapter is the kind of connector worth keeping on hand for both planned installations and unexpected repairs. Whether you are plumbing a new drain line or adapting tubing to existing threaded hardware, it bridges rigid and flexible plumbing with confidence. Because drain connections often run continuously during regeneration, a secure, properly clamped barb fitting like this one is cheap insurance against the slow leaks that can quietly damage a utility room over time. When selecting hose for the barb, choosing tubing rated for the temperature and pressure of your application ensures the whole connection performs as a system, with no single component limiting the reliability of the others.
