Brass Reducing Coupling FERRO R11Z 2x1¼" – reducing fitting, threaded plumbing connector

FERRO R11Z 2x1¼" is a brass reducing coupling with two 1¼" threaded ends designed for plumbing installations. The fitting provides a threaded transition between pipes or fixtures of the same nominal connection size, offering a compact and corrosion-resistant brass joint suitable for water and heating systems in residential and commercial applications.

Advantages

The brass construction ensures good resistance to corrosion and mechanical wear, while threaded ends allow for straightforward assembly and disassembly without special tools. Its compact form factor enables installation in confined spaces and provides a reliable metal-to-metal connection that withstands typical domestic and commercial water system conditions.

Suitable for

• Joining pipe sections with 1¼" threaded connections
• Connecting fixtures and valves in water distribution systems
• Heating system pipework where threaded reducing joints are required
• Repair or modification of existing threaded plumbing installations

Key specifications

• Material: brass
• Connection type: threaded coupling
• End size: 1¼" × 1¼" (reducing coupling form)
• Application: potable water and heating systems
• Installation orientation: inline

How to use

Prepare mating threads by cleaning debris and inspecting for damage. Apply an appropriate thread sealant or PTFE tape to the male threads following sealant manufacturer instructions. Screw the coupling onto the male thread by hand until finger-tight, then tighten with a suitable wrench to secure a leak-free joint; avoid over-tightening to prevent thread damage. For installations in heating systems, ensure the circuit is depressurized and drained according to local regulations before fitting.

Usage recommendations

Use compatible thread sealants and follow local plumbing codes. Check for compatibility with system media and operating temperatures, and perform a pressure test after installation to confirm leak-tightness.
