Metal threaded coupling (mufa) 40 mm, male thread 5/4" — Detal-met

Detal-met metal threaded coupling (mufa) 40 mm with a 5/4" male thread is designed to create a durable threaded connection between compatible pipes and fittings in water supply and heating systems. The coupling's metal construction provides mechanical strength and resistance to deformation under tightening torque, making it suitable for installations where a secure, long-lasting connection is required.

Advantages

The metal body ensures high mechanical strength and reliable thread engagement, reducing the risk of leaks when correctly installed. Its standardized nominal diameter and thread form allow compatibility with a range of metal and compatible fittings. The part offers good resistance to temperature variations typical for domestic water and central heating systems and withstands repeated assembly and disassembly without significant wear when proper sealing materials are used.

Suitable for

• Joining metal pipes in hot and cold water supply systems
• Connecting components in central heating installations
• Repairing or extending threaded plumbing runs
• Applications requiring a robust mechanical threaded joint

Key specifications

• Nominal diameter: 40 mm
• Thread type: male threaded connector
• Thread size: 5/4" (one and one quarter inch) male
• Material: metal construction suitable for plumbing use
• Typical applications: water supply and heating systems

How to use

Ensure mating threads on pipes or fittings are clean and free of debris. Apply an appropriate thread sealant or sealing tape to the male thread according to the sealing material manufacturer's instructions. Hand-start the coupling onto the female thread to avoid cross-threading, then tighten with the appropriate wrench until a secure, leak-tight joint is achieved without over-tightening. Follow local plumbing codes and installation best practices for support and alignment of the connected piping.

Usage recommendations

Use compatible thread sealants for potable water systems if required by regulations; verify material compatibility with system fluids and operating temperatures. Inspect threaded joints periodically for signs of corrosion or loosening, and replace the coupling if significant wear or damage is observed.
