Compression reducing coupler Herz P 7032 02, sizes 32x3 to 20x2

The Herz compression reducing coupler P 7032 02 connects two copper or multilayer pipes with different outer diameters, enabling a secure transition from 32x3 to 20x2 pipe dimensions. Designed for plumbing and heating systems, this mechanical reduction fitting ensures a tight, leak-resistant joint without the need for soldering or welding. The coupler is intended for use in potable water lines, heating circuits and general pipework where a durable and compact reduction is required.

Advantages

The coupling offers a compact, space-saving design that allows straightforward installation in confined areas. Its compression connection provides a reliable seal under typical domestic and commercial water and heating pressures, reducing the risk of leaks when installed according to manufacturer guidelines. The design minimizes the need for additional tools or heat sources, which speeds up installation and reduces on-site risks. Compatibility with common 32x3 and 20x2 pipes makes it suitable for retrofit work and new installations alike.

Suitable for

• Transitioning between larger and smaller copper or multilayer pipes in domestic plumbing
• Connecting different pipe sizes within heating circuits and radiator feeds
• Repair and replacement tasks where a secure mechanical reduction is required
• Installations where solder-free connections are preferred or required

Key specifications

• Connection type: compression reducing coupler
• Suitable pipe outer dimensions: 32x3 to 20x2
• Material compatibility: copper and multilayer (PEX-al-PEX) pipes
• Intended media: potable water and heating fluids
• Installation method: mechanical compression, no soldering required

How to use

Prepare the pipes by cutting them square and deburring the cut ends. Slide the compression nut and olive (ferrule) onto each pipe end, insert the smaller and larger pipe ends into the respective sides of the coupler until they reach the internal stop. Tighten the compression nuts evenly by hand and then with an appropriate wrench to the recommended torque or until the connection is firm and leak-free. After installation, pressurize the system and check for leaks; re-tighten nuts if minor seepage is observed following the manufacturer’s guidance.

Usage recommendations

Use the coupler only with the specified pipe dimensions and materials; inspect olives and nuts for correct seating during installation. For installations carrying potable water, follow local codes and flush the system after fitting. Where higher system pressures or aggressive fluids are present, verify material compatibility and service limits before installation.
