IBP brass nipple 18 x 3/4" GZ threaded fitting, model 4243G018006000

IBP brass nipple 18 x 3/4" GZ threaded fitting, model 4243G018006000 is a compact brass connector designed for joining 18 mm pipes to 3/4" female threaded ports. The fitting features an external (GZ) thread on one end and a smooth cylindrical section for insertion or connection to compatible pipe ends on the other. It is intended for use in plumbing and heating systems where a robust, corrosion-resistant metallic join is required for water supply, radiator connections and valve installations.

Advantages

The brass construction provides good corrosion resistance and mechanical strength suitable for potable water and central heating systems. The GZ external thread ensures a standardized threaded connection to 3/4" female fittings, offering reliable sealing when used with appropriate tape or sealant. Its compact dimensions make it suitable for installations with limited space and for straightforward, repeatable connections during repairs or new installations.

Suitable for

• Connecting 18 mm copper or compatible pipes to 3/4" threaded ports
• Domestic water supply lines
• Radiator and heating circuit connections
• Attachment of valves, taps or other threaded fittings

Key specifications

• Material: brass
• Connection A: 18 mm pipe-compatible end
• Connection B: 3/4" external (GZ) thread
• Typical applications: plumbing and heating systems
• Finish: machined brass surface

How to use

Prepare both the pipe end and the mating threaded port by cleaning away dirt and burrs. If required, secure the pipe end according to the pipe type (push-fit, soldering, compression or appropriate adapter) so that the brass nipple seats correctly. Apply thread sealant tape or a suitable pipe joint compound to the GZ external thread to ensure a water-tight joint, then hand-thread into the female 3/4" port and tighten with an appropriate wrench until secure; avoid over-tightening to prevent thread damage. After installation, pressurize the system and check for leaks at the connection.

Usage recommendations

Use with compatible 18 mm pipe materials and standard 3/4" female fittings. Select a thread sealant compatible with potable water if used on drinking-water systems. Follow local plumbing codes and practice appropriate installation methods (e.g., soldering or compression fittings) for the pipe type in use.
