Suitable for domestic and commercial water installations where a threaded-to-pipe transition is required.

## Long description

Brass Extension Pipe Perfexim WZ 3/4" x 20mm PN16 — connection fitting is a brass pipe extension designed to join a 3/4" threaded inlet to a 20 mm pipe in water distribution systems. Manufactured by Perfexim with a PN16 pressure rating, this connector provides a solid brass transition between threaded fittings and smooth or compression-fit 20 mm plumbing lines. The fitting is intended for use where a reliable, corrosion-resistant metal connection is required in domestic or commercial installations.
Advantages
The brass construction offers corrosion resistance and long service life in contact with potable water. A PN16 pressure rating ensures compatibility with standard low- to medium-pressure plumbing systems. The WZ 3/4" thread provides a secure threaded connection while the 20 mm end adapts to common pipe dimensions, minimizing the need for additional adapters. The single-piece design simplifies installation and reduces potential leak points compared with multi-component adapters.
Suitable for
Connecting 3/4" threaded fittings to 20 mm copper or plastic water pipes
Domestic potable water supply lines and fixture connections
Commercial plumbing installations with PN16 pressure requirements
Retrofit or repair work where a threaded-to-smooth pipe transition is needed
Key specifications
Material: brass
Thread type: WZ 3/4" (threaded connection)
Connection diameter: 20 mm (pipe end)
Pressure rating: PN16
Application: water distribution and plumbing systems
How to use
Prepare both the threaded fitting and the 20 mm pipe by cleaning contact surfaces and removing debris or burrs. Apply appropriate thread sealant such as PTFE tape or liquid thread sealant to the 3/4" male threads if required by the installation. Screw the Perfexim brass extension into the threaded fitting until hand-tight, then tighten with an appropriate wrench to the manufacturer's recommended torque or until a secure, leak-free connection is achieved. Insert the 20 mm pipe into the connection end using the installation method compatible with the pipe type (soldering, compression fitting, or push-fit) as applicable for the system.
Usage recommendations
Verify material compatibility between the brass fitting and pipe material to avoid galvanic corrosion in mixed-metal systems; use dielectric unions or appropriate fittings where necessary. Follow local plumbing codes and pressure testing procedures after installation to confirm leak-free operation. For potable water applications, ensure all sealing materials are approved for contact with drinking water.
