KAN-therm press fitting 22 mm x RP 1/2" with external thread from the Steel Press series is a mechanical transition fitting designed to connect 22 mm piping to a female Rp 1/2" threaded outlet. The fitting features a male Rp 1/2" external thread and a press-connection end for 22 mm pipes, providing a gas- and watertight joint when installed with compatible press-installation tools and jaws. It is intended for use in heating systems and potable water installations where a robust steel press connection is required.

Advantages

The Steel Press construction offers high mechanical strength and corrosion resistance suitable for building services applications. The press connection enables fast, reliable assembly without soldering or welding, reducing installation time and on-site work. The integrated external thread provides a standardized connection to female Rp 1/2" fittings or valves, ensuring compatibility with common plumbing components. When installed with approved press tools and correct technique, the fitting forms a durable, leak-tight joint.

Suitable for

• Connecting 22 mm copper or steel piping to female Rp 1/2" threaded valves or fixtures
• Domestic and commercial heating systems
• Potable water supply installations where press fittings are specified
• Retrofit projects requiring a mechanical transition to a threaded outlet

Key specifications

• Connection A: 22 mm press end for compatible press jaws
• Connection B: external male Rp 1/2" thread (for female Rp 1/2" fittings)
• Material: steel press fitting body suitable for heating and potable water systems
• Assembly method: press installation using compatible press tools and jaws
• Application temperature and pressure: suitable for typical heating and potable water ranges when used per manufacturer guidelines

How to use

Prepare the 22 mm pipe by cutting squarely and deburring the internal and external edges. Slide the press fitting onto the prepared pipe end until it seats fully against the internal stop. Position the appropriate press jaw around the press sleeve according to the press tool manufacturer’s instructions, ensuring correct alignment. Activate the press tool to form the permanent mechanical joint. Thread the male Rp 1/2" end into the corresponding female Rp 1/2" component using appropriate thread sealant or tape if required by the installation practice. After assembly, perform pressure testing of the system to verify the integrity of the connection.

Usage recommendations

Use only press tools and jaws approved for KAN-therm Steel Press fittings. Observe manufacturer installation instructions, applicable codes, and pressure testing procedures. Avoid using damaged fittings or improperly prepared pipe ends to ensure reliable, leak-free operation.
