KAN-therm plumbing fitting 40x3.5 G1 1/2" with external thread K-900008

KAN-therm K-900008 is a plumbing coupling measuring 40x3.5 mm with an external G1 1/2" thread designed for joining plastic or metal pipes in heating and plumbing systems. The coupling provides a threaded connection that enables secure attachment to compatible fittings, valves or fixtures, allowing easy integration into residential and commercial installations where a G1 1/2" external thread interface is required.

Advantages

The coupling offers a standardized external G1 1/2" thread for compatibility with a wide range of threaded fittings and fixtures. Its 40x3.5 mm pipe dimension is suitable for common plumbing runs, and the design facilitates a reliable mechanical connection when combined with appropriate sealing materials. The component is constructed to meet typical installation tolerances and to enable straightforward assembly in confined or accessible locations.

Suitable for

• Connecting 40x3.5 mm pipes in heating circuits and domestic plumbing
• Providing an external G1 1/2" threaded interface for valves, meters or fixtures
• Use in renovation and new-build residential or commercial installations

Key specifications

• Pipe outside diameter and wall thickness: 40x3.5 mm
• Thread type: external G1 1/2" (parallel pipe thread)
• Function: threaded coupling for joining pipe to threaded fittings or fixtures
• Typical applications: heating systems, potable water distribution, plumbing connections
• Mechanical connection intended for use with appropriate sealing tape, joint compound or gasket

How to use

Prepare the pipe ends by cutting square and deburring the inner and outer edges. Ensure threads on the coupling and mating fitting are clean and undamaged. Apply an appropriate thread sealing method—such as PTFE tape or compatible thread sealant—on the external thread following manufacturer guidance. Screw the coupling into the mating component by hand until engagement, then tighten with a suitable wrench to achieve a secure fit without over-torquing. When joining to a pipe, follow the pipe system manufacturer’s instructions for insertion depth and any additional fastening or compression steps required.

Usage recommendations

Verify compatibility of materials and pressure/temperature ratings between the coupling, pipes and connected components before installation. Use recommended sealing materials for G1 1/2" threads and avoid excessive torque to prevent thread damage. Inspect joints after initial pressurization and periodically as part of system maintenance.
