Brass Reducing Nipple FERRO N17Z 6/4 x 5/4" – threaded plumbing fitting

FERRO N17Z is a brass reducing nipple with threaded connections sized 6/4 x 5/4". Intended for plumbing installations, this metal fitting connects two threaded pipes or components of different diameters to create a sealed transition. Made of brass, the reducing nipple is suitable for potable water systems and general plumbing applications where a durable, corrosion-resistant threaded reduction is required.

Advantages

The brass construction provides good resistance to corrosion and mechanical wear, ensuring a long service life in typical domestic and commercial water systems. Threaded connections allow for easy installation and disassembly without soldering, while the reducing design enables a secure and leak-resistant transition between mismatched pipe diameters. The compact form factor and standardized thread sizes make the fitting compatible with common plumbing components.

Suitable for

• Reducing threaded connections between 6/4" and 5/4" pipe fittings
• Domestic and commercial cold and hot water plumbing systems
• Repair and replacement of threaded plumbing components
• Temporary or permanent installations where a metal threaded reduction is preferred

Key specifications

• Material: brass
• Connection type: threaded
• Size: reducing nipple 6/4" x 5/4"
• Application: water plumbing systems (cold and hot)
• Finish: metallic (uncoated brass)

How to use

Prepare the mating threads by cleaning debris and old sealing material. Apply an appropriate thread sealant such as PTFE tape or pipe thread compound to the male threads to ensure a leak-tight joint. Screw the reducing nipple into the larger diameter fitting or pipe first, then attach the smaller diameter component and tighten by hand. Use suitable wrenches to complete the final tightening, taking care not to overtighten and risk thread damage. Inspect the connection for leaks after pressurizing the system.

Usage recommendations

Use PTFE tape or approved thread sealant on tapered threads to improve sealing. Avoid excessive torque during installation; tighten until snug and then apply a measured additional turn with a wrench. Verify compatibility of materials with system fluids and temperatures before installation. For potable water installations, ensure the brass grade meets local potable water regulations.
