Shop 5503 45-Degree Male NPT - Female NPT Street Elbow
SAE 140339
The Series 5503 45-Degree Male NPT x Female NPT Street Elbow adapters, made from durable carbon steel, are commonly used in fluid and gas transfer systems to create angled connections. These adapters feature male and female NPT (National Pipe Tapered) threads, a U.S. standard for tapered threads that provide a secure, leak-free seal when tightened. The 45-degree angle allows for flexible directional changes in piping systems, making them ideal for tight spaces or complex installations. Available in carbon steel for high-pressure applications, as well as iron and brass for low-pressure uses, these adapters are designed for reliability and long-lasting performance in various industrial applications. The nominal pipe size is determined by measuring the thread diameter and subtracting 1/4".
