Brass Reducing Coupling FERRO R08Z 1½" x 1¼" (female/male)

FERRO R08Z 1½" x 1¼" brass reducing coupling (female/male) is a threaded plumbing fitting designed to join pipes or fittings of different diameters. Manufactured from brass for corrosion resistance and mechanical durability, this reducing coupling provides a compact transition between 1½" and 1¼" threaded connections commonly used in water installations and heating systems. The part features standard metric/imperial-compatible threads to simplify installation with commonly available threaded pipes and accessories.

Advantages

The brass construction offers good resistance to corrosion and scaling while maintaining structural strength under normal domestic water pressure. The reducing design allows a secure, leak-minimizing connection between mismatched pipe sizes without the need for extensive modification. Threaded female-to-male configuration ensures straightforward assembly and disassembly for maintenance or replacement and is compatible with standard threaded plumbing components.

Suitable for

• Domestic water supply connections where a reduction from 1½" to 1¼" is required
• Heating system pipework and radiator connections with compatible threads
• General plumbing repairs and retrofits in bathrooms, kitchens, and utility rooms
• Temporary or permanent installations using threaded fittings

Key specifications

• Material: brass for corrosion resistance
• Connection type: female-to-male threaded reducing coupling
• Size: reduces from 1½" to 1¼" nominal pipe diameter
• Application: potable water, heating systems, general domestic plumbing
• Design: compact, single-piece reducing adapter for threaded pipes

How to use

Before installation, ensure both mating threads are clean and free from debris or damaged threads. Apply an appropriate thread sealant or PTFE tape to the male threads following manufacturer recommendations for the installation environment and fluid type. Hand-start the coupling onto the male thread, then tighten with an adjustable wrench or spanner until secure; avoid over-tightening to prevent thread or fitting damage. Inspect the joint for leaks after pressurizing the system and re-tighten slightly if required. For disassembly, relieve system pressure and unthread using the appropriate tool.

Usage recommendations

Use only in systems whose materials and operating conditions are compatible with brass. For potable water installations, follow local plumbing codes and guidelines regarding joint sealants and allowable materials. Do not expose the fitting to aggressive chemicals or environments that can cause dezincification without verifying material suitability.
