The Water Source MA50NL is a high-quality, precision-engineered brass male insert adapter designed to provide a secure and leak-resistant connection between flexible poly or PVC tubing and threaded metal piping systems. With a 1/2-inch male NPT (National Pipe Thread) on one end and a 1/2-inch insert barb on the other, this fitting is ideal for irrigation systems, pump connections, and a wide range of residential, agricultural, and light commercial plumbing applications.

Key Features:

• Dual Connection Design: Features a 1/2" MNPT threaded end for connecting to iron or brass fittings, and a 1/2" barbed end for secure insertion into flexible poly or PVC tubing.
• Durable Brass Construction: Made from solid yellow brass, this adapter offers excellent corrosion resistance, mechanical strength, and longevity—even in outdoor or wet environments.
• Lead-Free Compliance: Meets federal low-lead regulations (NSF/ANSI 61 certified), making it safe for potable water systems.
• Leak-Resistant Performance: Designed for tight, secure connections. Use thread seal tape on the MNPT threads and hose clamps (not included) on the barbed end to ensure a watertight seal.
• Versatile Use: Commonly used in well pump systems, sprinkler setups, garden irrigation, and low-pressure fluid transfer applications.
• Compact & Lightweight: Measures approximately 2.5 inches in length, with a weight of just 0.14–0.15 lbs, making it easy to install in tight spaces.
