Compression union KAN-therm 22 mm x R½ with internal thread (model 6302708)

KAN-therm compression union 22 mm x R½ with internal thread is a compact pipe fitting designed to connect a 22 mm plastic or metal pipe to a female R½ threaded component. The fitting provides a mechanical compression joint on the pipe side and a cylindrical internal female thread on the other, enabling a secure transition between pipework and threaded valves, taps or appliances in potable water and heating systems. The model is intended for installations where a reliable, leak-tight connection and minimal space usage are required.

Advantages

The compression design ensures a strong, reusable connection without soldering or adhesive, allowing straightforward assembly and disassembly during maintenance. The internal thread provides compatibility with standard R½ threaded components, simplifying integration into existing plumbing and heating networks. The compact form factor minimizes space requirements near fixtures and valves while maintaining a sealed joint suitable for potable water and heating circuits.

Suitable for

• Connecting 22 mm plastic or metal pipe to female R½ threaded valves or fittings
• Domestic potable water installations
• Heating circuits and radiators
• Repair and retrofit work where a compact threaded transition is needed

Key specifications

• Pipe connection size: 22 mm (compression)
• Thread type: internal female R½
• Connection method: mechanical compression union
• Application: potable water and heating systems
• Form factor: compact angled/inline union for tight spaces

How to use

Prepare the 22 mm pipe by cutting square and deburring the end to ensure a smooth surface for the compression sleeve. Slide the compression nut and ferrule onto the pipe, insert the pipe end fully into the union body, then tighten the compression nut to the recommended torque to create a leak-tight seal. Thread the R½ female side onto the mating male threaded component using appropriate sealing tape or compound on the male threads if required by the installation practice. After assembly, pressurize the system and inspect the joint for leaks.

Usage recommendations

Use appropriate O-rings or thread sealants compatible with potable water where applicable, and follow local plumbing codes. Avoid over-tightening the compression nut to prevent deformation of the pipe or ferrule; consult manufacturer torque guidance when available. For installations involving high temperatures or aggressive media, verify material compatibility prior to use.
