Brass threaded elbow 5/4" FERRO K13Z — plumbing fitting, male-female 90° connection

FERRO K13Z is a brass threaded elbow with a 5/4" nominal size designed for plumbing installations that require a 90° male-to-female threaded connection. The fitting is manufactured from corrosion-resistant brass and provides a compact right-angle transition between threaded pipes or fixtures. It is intended for general plumbing use, including potable water systems and commercial or residential piping assemblies where a durable threaded elbow is needed.

Advantages

The brass construction ensures long-term resistance to corrosion and scaling while maintaining mechanical strength under normal plumbing conditions. The male-female 90° configuration simplifies changes in flow direction without soldering or welding, and the standard 5/4" thread size fits compatible threaded components. The component is compact, provides a reliable seal when used with appropriate sealing material, and is suitable for repeated assembly and disassembly during maintenance.

Suitable for

• Right-angle connections in potable water supply lines
• Threaded transitions between pipes and fixtures in residential plumbing
• Commercial piping assemblies requiring a durable brass elbow
• Maintenance situations where threaded, reusable joints are needed

Key specifications

• Material: brass, corrosion-resistant
• Nominal size: 5/4" (threaded)
• Connection type: male-to-female threaded 90° elbow
• Application: potable water and general plumbing systems
• Shape: right-angle elbow for directional change

How to use

Before installation, inspect mating threads for damage and clean both male and female threads. Apply an appropriate thread sealant or PTFE tape to the male threads, following the sealant manufacturer's instructions. Screw the male thread into the female thread by hand to engage the threads, then tighten with a suitable wrench until the joint is secure; avoid excessive torque to prevent thread deformation. Align the elbow to the required orientation for the 90° turn and verify leak-tightness after pressurizing the system. For potable water applications, ensure compatible sealing materials are used and perform a pressure test according to local codes.

Usage recommendations

Use compatible thread sealants and follow local plumbing codes. Avoid over-tightening and inspect periodically for signs of corrosion or leaks. For systems with dissimilar metals, consider appropriate dielectric fittings or protective measures to reduce galvanic corrosion.
