## Long description

KAN-therm copper union fitting 22 Rp3/4 (S) is a mechanical connector for joining 22 mm copper pipes to components with an Rp 3/4 female thread. The fitting provides a removable, sealed connection that simplifies maintenance and replacement in plumbing and heating installations. It is intended for use in potable water, heating, and sanitary systems where a combination of soldered or push-fit copper piping and threaded components is required.
Advantages
The copper union fitting offers a reliable metal-to-metal connection with corrosion-resistant properties inherent to copper. Its design allows easy disassembly without cutting pipes, facilitating servicing and component replacement. Compatibility with standard 22 mm copper pipe dimensions and Rp 3/4 female threaded components ensures straightforward integration into existing systems. The fitting supports sealed joints suitable for potable water and heating applications when installed according to accepted practices.
Suitable for
Connecting 22 mm copper pipes to Rp 3/4 threaded valves, pumps, or fittings
Hot and cold potable water distribution systems
Central heating circuits and radiator connections
Sanitary installations requiring removable joints for maintenance
Key specifications
Material: copper
Pipe diameter compatibility: 22 mm
Thread type: Rp 3/4 (female thread interface)
Connection type: union (removable threaded joint)
Application temperature: suitable for typical potable water and heating system temperatures
How to use
Prepare the copper pipe end by cutting square and deburring the inner and outer edges. If the fitting requires soldering, clean and flux mating surfaces and perform a proper capillary solder joint according to accepted plumbing standards. For installations where the copper union is used to join to a threaded component, hand-start the Rp 3/4 thread and tighten to the recommended torque using appropriate wrenches; use a suitable sealing method on the thread if required by the installation (for example, PTFE tape or pipe joint compound compatible with potable water). After assembly, inspect the joint and perform a pressure test in line with local codes to verify leak-tightness.
Usage recommendations
Install and inspect the copper union fitting in accordance with local plumbing and heating regulations. Use materials and sealing compounds approved for potable water when applying thread sealants. Avoid excessive mechanical stress and ensure proper support of connected pipes and components to prevent fatigue at the union joint.
