The 809 3/8 x 3/8 Elbow Female Pipe Thread is a brass elbow fitting with female pipe threads (FPT) on both ends, designed to create a 45-degree turn in the piping system. This fitting is commonly used in systems such as fuel, gas, hydraulic, refrigeration, and HVAC systems where a 45-degree directional change is needed while ensuring a secure, threaded connection. The brass construction offers long-lasting durability, corrosion resistance, and reliable performance in both high and low-pressure systems.
