1/2" X 50mm CP Extension Nipple

CP refers to a copper alloy material used for the fitting. Copper alloy fittings are typically strong, durable, and corrosion resistant, making them suitable for many plumbing environments and potable-water applications when properly rated.

The nipple is 1/2" nominal size with a 50mm overall length. It is an exterior nipple (has male threads on both ends). The product page describes CP material and exterior threading, but it does not specify the thread standard (e.g., NPT vs. BSP). Verify compatibility with your system’s thread type before use.

Before installation, ensure the pipe ends are clean and cut square. Wrap or apply a suitable sealant/teflon tape compatible with copper fittings to the male threads, then hand-tighten and finish with a wrench to the recommended torque. Avoid over-tightening to prevent thread damage.

Yes, you typically use a thread sealant appropriate for metal pipe connections. For most metal-threaded nipples, PTFE tape or a pipe-dope designed for copper systems is recommended. Apply it evenly without over-wrapping to ensure a proper seal.

Copper alloy fittings are commonly used in potable-water systems, but always ensure the specific product is lead-free and rated for potable use. Follow local codes and use compatible, lead-free fittings when connecting to drinking-water lines.

This exterior nipple is designed for pipe-to-pipe connections and is most compatible with metal piping systems. When joining to plastic pipes or non-metal fittings, use appropriate adapters and ensure the assembly remains leak-free and compliant with your system’s materials.

It’s well-suited for extending a copper or CP-plated piping run, repairing a short section, or creating a clean inline connection in domestic water systems, heating lines, or irrigation setups where a small, rigid connector is needed.

Periodically check the threaded connections for leaks, especially after temperature or pressure fluctuations. Re-torque as needed within recommended limits, and replace any fittings showing corrosion, wear, or damage to maintain system integrity.

If the product doesn’t meet your requirements, you can initiate a return according to Fepy’s standard return terms. Ensure the item is unused, in its original packaging, and returned within the allowed window for a smooth refund or exchange process.

Consider: the thread type compatibility with your connectors (NPT vs. BSP), whether the 50mm length fits your run, whether the CP material is suitable for your water temperature and pressure, and whether you need a lead-free option for potable water. Also verify fit with your existing piping system and the appropriate sealant or tape to ensure a leak-free connection.
