KAN-therm push-fit coupling with flange, external thread 25x3.5 mm 1/2" model 9014.98

KAN-therm push-fit coupling with flange, external thread 25x3.5 mm 1/2" model 9014.98 is a mechanical joining component designed to connect 25x3.5 mm plastic or multilayer pipes to a 1/2" threaded interface. The coupling uses a push-fit connection on the pipe side and a threaded flange on the opposite side, providing a reliable transition between push-fit plumbing systems and threaded valves, fixtures or fittings without the need for soldering, gluing or specialized tools.

Advantages

The coupling enables rapid assembly and disassembly of plumbing connections while maintaining leak-resistant performance when installed correctly. Its push-fit side accepts 25x3.5 mm pipes securely, and the external 1/2" thread allows straightforward attachment to standard threaded components. The design reduces installation time and minimizes the requirement for separate sealing materials when used with appropriate thread sealing methods. Materials and construction are intended for typical domestic and commercial plumbing and heating applications.

Suitable for

• Connecting 25x3.5 mm plastic or multilayer pipes to 1/2" threaded valves and fittings
• Service and replacement tasks where a threaded interface is required
• Plumbing and heating systems in residential and light commercial buildings

Key specifications

• Pipe compatibility: 25 x 3.5 mm plastic or multilayer pipes
• Thread type: external 1/2" thread suitable for standard threaded fittings
• Connection type: push-fit on pipe side, threaded flange on opposite side
• Installation: mechanical push-fit assembly without soldering or adhesives
• Typical applications: water supply and heating circuits

How to use

Ensure the pipe end is cut squarely, deburred and free from damage or contaminants. Push the pipe firmly into the coupling until it reaches the internal stop; verify engagement by a tactile click or resistance according to the manufacturer's assembly practice. Apply appropriate thread sealing tape or compound to the external 1/2" thread if required by the mating component, then hand-tighten and finish with an appropriate tool to the recommended torque for the downstream fitting. After assembly, check the connection for leaks under working pressure.

Usage recommendations

Use the coupling only with compatible 25x3.5 mm pipes and standard 1/2" threaded fittings. Follow local plumbing codes and the pipe manufacturer's guidelines regarding pressure, temperature limits and approved sealants. Periodically inspect installed joints for signs of wear or leakage, and replace the coupling if damage or persistent leaks occur.
