3/4" X 1/2" CP Reducer

One end is 3/4" female threaded and the other end is 1/2" male threaded. In use, the female side accepts a 3/4" male threaded pipe, while the male side threads into a compatible female connection.

It’s made from copper. Copper is durable and resistant to corrosion and rust, making it suitable for plumbing applications and providing a reliable long-term connection.

It’s suitable for water supply lines and other plumbing installations where you need to reduce from a 3/4" pipe to a 1/2" pipe. It works in a variety of plumbing scenarios that use threaded copper fittings.

1) Ensure the system is depressurized and drained. 2) Clean the mating threads on both pipes. 3) Apply an appropriate thread sealant or PTFE tape rated for copper/plumbing on the male threads. 4) Hand-tighten the reducer onto the 3/4" side, then snug with a wrench without overtightening. 5) Tighten the 1/2" male side similarly. 6) Pressurize the system and check for leaks, tightening slightly if needed.

You’ll typically need a wrench or adjustable pliers, PTFE thread seal tape or pipe thread sealant rated for copper, and a clean rag to wipe away excess sealant. Have a flashlight handy to inspect the joints after testing.

Use an appropriate pipe thread sealant or PTFE tape on the threaded connections, ensure threads are clean, and tighten to a snug fit without overtightening. After tighening, pressurize the system slowly and inspect both ends for any signs of leaks.

Copper fittings like this reducer are designed for typical household plumbing conditions, including standard temperatures and pressures. They are meant to operate under common domestic usage, but always ensure compatibility with your local codes and system specifications.

Yes. Use approved thread sealants and follow local plumbing codes. Depressurize the system before work, ensure clean threads, and avoid over-tightening to prevent damage to threads or fittings.

This reducer provides a 3/4" female to 1/2" male threaded connection in copper, ideal for reducing pipe size in a secure threaded joint. For other size reductions, you can consider similar copper reducers on Fepy such as the 1/2" x 1/4" CP Reducer (https://fepy.com/products/1-2-x-1-4-cp-reducer) or the 1" x 1/2" CP Reducer (https://fepy.com/products/1-x-1-2-cp-reducer) to match different system requirements.

Confirm that one end’s threads match 3/4" and the other end matches 1/2". Ensure you’re using threaded copper connections (not compression). If you’re unsure about the thread standard (NPT vs. BSP), verify with the pipe manufacturer or local codes, and compare to other copper threaded fittings on Fepy for a perfect match.
