Brass coupling Fitting SF60N-5/4 — threaded pipe connector 5/4"

Brass coupling Fitting SF60N-5/4 is a threaded pipe connector designed for joining two compatible 5/4" threaded pipes or fittings. Manufactured from brass, this coupling provides corrosion resistance and mechanical strength required for plumbing and heating systems. It creates a secure threaded seal suitable for water supply, heating circuits and general utility piping where a 5/4" brass coupling is specified.

Advantages

The brass construction offers good resistance to corrosion and moderate mechanical wear while remaining easy to machine and install. Threaded ends ensure a direct mechanical connection without the need for soldering or welding, enabling quick assembly and disassembly for maintenance. The compact cylindrical form provides minimal flow disruption and fits standard 5/4" threaded pipe systems, making it a straightforward choice for repairs and new installations.

Suitable for

• Joining two 5/4" threaded metal or compatible plastic pipes in plumbing systems
• Connecting sections of heating circuits and radiator piping
• Repairing or extending utility piping in residential and commercial buildings
• Applications where a threaded, removable brass coupling is required

Key specifications

• Material: brass for corrosion resistance and mechanical strength
• Connection type: threaded coupling, both ends 5/4"
• Shape: cylindrical coupling designed for inline joining
• Typical media: water and heating fluids in closed systems
• Installation: mechanical thread connection, no soldering required

How to use

Prepare the threaded pipe ends by cleaning threads and removing debris or old sealing material. Apply an appropriate thread sealant or PTFE tape to the male threads following the sealant manufacturer's instructions. Screw the coupling onto the first pipe by hand until engaged, then tighten with a suitable wrench to the recommended torque for 5/4" fittings to achieve a leak-free connection. Align the second pipe and repeat the process, ensuring the coupling is not overtightened to avoid thread damage. After installation, pressurize the system and inspect for leaks.

Usage recommendations

Use compatible thread sealants rated for potable water or heating systems when required. Check material compatibility if the coupling is used with dissimilar metals to avoid galvanic corrosion. For high-temperature or high-pressure systems, confirm that brass is an appropriate material and follow local plumbing codes and standards.
