45° Stainless Steel Female Thread Elbow
45° Stainless Steel Female Thread Elbow | SSM
SSM is a trusted global manufacturer and supplier of 45° Stainless Steel Female Thread Elbows, designed for reliable pipe connection, directional flow control, and corrosion-resistant performance in industrial, marine, hydraulic, pneumatic, and instrumentation systems.
The 45° Stainless Steel Female Thread Elbow is a threaded pipe fitting used to change the direction of fluid flow by 45 degrees. Manufactured from high-quality stainless steel materials, it provides excellent corrosion resistance, mechanical strength, and long service life in demanding operating environments.
1. Product Overview
The 45° Stainless Steel Female Thread Elbow is designed with female threaded connections on both ends, allowing direct connection with male threaded pipes, tubes, valves, and other fittings.
Compared with welded elbows, threaded elbows offer faster installation, easier maintenance, and convenient replacement without specialized welding equipment. The 45-degree angle design provides a smooth directional change while minimizing pressure loss and turbulence in piping systems.
