Ferro Nypel GZ 2" - N08Z threaded nipple for pipe connections

Ferro Nypel GZ 2" - model N08Z is a threaded metal nipple designed for joining and extending pipe runs with 2" GZ (female) threaded connections. Manufactured by FERRO, the fitting provides a short, robust coupling between two internally threaded fittings or pipes of the same nominal size. The nipple is intended for use in plumbing, heating and water supply installations where a durable metal threaded connector is required.

Advantages

The nipple offers a compact and rigid connection that simplifies alignment of threaded pipe elements and minimizes the need for additional couplings. Made of metal, it delivers mechanical strength, resistance to deformation under torque and reliable sealing when used with appropriate thread sealant. Its standardized 2" GZ thread ensures compatibility with other fittings and components designed to the same thread form and nominal size.

Suitable for

• Connecting two female-threaded pipes or fittings with 2" GZ threads
• Extending or repairing short sections of threaded pipe runs
• Plumbing and domestic water distribution systems
• Heating installations and radiators where threaded connections are used

Key specifications

• Thread type: female GZ (compatible with 2" male threaded fittings)
• Nominal size: 2 inches
• Material: metal construction for mechanical strength
• Form: short nipple for direct coupling between two female-threaded parts

How to use

Apply an appropriate thread sealant (PTFE tape or liquid sealant) to the male thread of the mating fittings before assembly to ensure a watertight joint. Screw the nipple into each female-threaded fitting by hand to start, then tighten with a suitable wrench until a secure fit is achieved. Avoid over-tightening to prevent thread damage or deformation. Inspect the assembled joint under pressure to confirm there are no leaks and re-tighten slightly if necessary following the sealant manufacturer’s guidance.

Usage recommendations

Use compatible 2" threaded fittings and standard thread sealants appropriate for potable water, heating, or other system media. For installations exposed to corrosion-prone environments, consider additional protective measures or material selection appropriate to the system. Verify thread compatibility before installation to ensure proper fit and sealing.
