Brass nipple SANHA 4243G GZ 15 mm x 1/2" (male-female pipe fitting)

SANHA Brass Nipple 4243G GZ 15 mm x 1/2" is a threaded male-female pipe fitting made from a bronze/brass alloy. It provides a GZ (parallel) threaded connection to join or extend piping where a 15 mm copper or installation pipe must be connected to a 1/2" threaded component. The fitting is manufactured for plumbing and heating systems and is suitable for potable water and general installation tasks that require a durable metal transition between metric and imperial thread sizes.

Advantages

The brass construction ensures corrosion resistance and mechanical strength in typical domestic and commercial plumbing conditions. The parallel GZ thread enables reliable sealing with appropriate sealing materials such as PTFE tape or thread sealant. Compact dimensions and standard threading make the nipple compatible with common plumbing valves, radiators, hoses, and fixtures that use 15 mm pipe and 1/2" threaded connections.

Suitable for

• Connecting 15 mm copper or installation pipe to 1/2" threaded fittings
• Extensions and repairs in potable water systems
• Heating system connections such as radiators and valves
• General plumbing installations requiring metric-to-imperial thread transition

Key specifications

• Material: brass/bronze alloy
• Connection type: male-female threaded nipple with parallel (GZ) thread
• Size: 15 mm (pipe end) to 1/2" (threaded end)
• Typical applications: potable water, heating, general installation
• Finish: machined brass surface

How to use

Ensure both connecting surfaces are clean and free of debris. Apply an appropriate thread sealant or PTFE tape to the male parallel thread if required by the installation practice. Hand-start the thread to avoid cross-threading, then tighten with suitable tools until a secure, leak-resistant connection is achieved; avoid excessive torque that could deform the fitting. After installation, inspect the joint under operating pressure and check for leaks.

Usage recommendations

Use compatible sealing materials for GZ parallel threads and follow local plumbing codes. Avoid exposing the fitting to aggressive chemicals or environments that could accelerate dezincification; use appropriate material choices where water quality or system conditions demand special alloys.
