Brass coupling FERRO M13Z 6/4 x 1" for plumbing connections

FERRO M13Z 6/4 x 1" brass coupling is a threaded plumbing fitting designed to join pipes or fittings with different thread dimensions, enabling a secure transition from 6/4 to 1" connections. Manufactured from brass, this coupling offers corrosion resistance and mechanical strength suitable for water and heating systems in residential and commercial installations. The compact design and threaded ends ensure straightforward installation where a reliable change of thread size is required.

Advantages

The brass material provides good resistance to corrosion and long-term durability in typical plumbing environments. Threaded ends allow leak-tight connections when installed with appropriate sealing (such as PTFE tape or thread sealant). The coupling's solid construction ensures stable mechanical performance under normal operating pressures for domestic water and heating circuits. Its compact form factor makes it suitable for confined spaces where a robust, threaded transition is needed.

Suitable for

• Connecting a 6/4 threaded pipe or fitting to a 1" threaded pipe or fitting
• Domestic water supply systems
• Heating circuits and radiators where mixed thread sizes occur
• Repair or modification of plumbing installations in apartments and houses
• Commercial plumbing applications requiring a durable threaded adapter

Key specifications

• Material: brass (corrosion-resistant plumbing brass)
• Connection type: threaded coupling (female/male or matching threaded ends depending on mating parts)
• Thread transition: 6/4 to 1"
• Intended media: potable water, heating fluids (water-based)
• Application environment: residential and commercial plumbing

How to use

Prior to installation, verify that thread types and sizes of the mating pipes or fittings match the coupling (6/4 and 1"). Clean threads on both mating parts and apply an appropriate thread sealant such as PTFE tape or a compatible liquid sealant to ensure a leak-free connection. Hand-start the coupling on the first thread to avoid cross-threading, then tighten with suitable wrenches until secure. Do not overtighten; follow standard plumbing torque guidance for brass fittings. After installation, pressurize the system and check for leaks, retightening slightly if necessary.

Usage recommendations

For long-lasting performance, avoid exposure to aggressive chemicals or highly acidic media. Use compatible sealing materials and avoid excessive mechanical stress on the coupling by supporting adjacent pipes. When used in potable water systems, ensure compliance with local regulations regarding materials for drinking water.
