FNPTxFNPT Black Cast Iron 45° Pipe Elbow

FNPT x FNPT Black Cast Iron 45° Pipe Elbow for Efficient Directional Flow

A FNPT x FNPT Black Cast Iron 45° Pipe Elbow is a threaded pipe fitting designed to change the direction of fluid flow by 45 degrees while maintaining efficient system performance. Featuring Female National Pipe Thread (FNPT) connections on both ends, this fitting creates secure, leak-resistant joints without the need for welding. Manufactured from high-quality black cast iron, these elbows are widely used in commercial plumbing, industrial piping, HVAC systems, irrigation, fire protection, and mechanical applications where strength and durability are essential.

The 45-degree angle provides a smoother transition than a 90-degree elbow, helping reduce flow restriction and pressure loss in many piping systems.

Durable Construction for Long-Term Performance

Black cast iron 45° elbows are engineered to withstand demanding environments while delivering dependable service over many years. Precision-machined FNPT threads ensure accurate alignment and tight connections when installed with PTFE tape or an approved thread sealant.

Available in multiple pipe sizes, these fittings are compatible with standard threaded pipe systems, making them an excellent choice for both new construction and maintenance projects.
