KAN-therm Ultraline fitting 20 mm — female thread 3/4" (model 2509044003)

The KAN-therm Ultraline fitting 20 mm — female thread 3/4" is a compact transition coupling designed to connect 20 mm plastic or composite pipes to components with a 3/4" internal thread. Intended for plumbing and heating systems, this fitting creates a secure interface between pipework and threaded valves, faucets, adapters or other fixtures. Its design focuses on ease of installation and compatibility with common residential and light-commercial piping materials.

Advantages

This fitting provides a reliable mechanical connection between 20 mm pipes and 3/4" internally threaded components without the need for additional adapters. The compact form factor minimizes space requirements in tight installation areas. The product is manufactured to meet typical industry expectations for dimensional compatibility and practical use in potable water and heating circuits. Simplicity of design reduces the number of potential leak points when installed correctly.

Suitable for

• Connecting 20 mm plastic or composite supply pipes to 3/4" threaded valves and fixtures
• Domestic hot and cold water distribution systems
• Heating system connections to radiators, manifolds or control valves
• Plumbing repairs and retrofits where a compact pipe-to-thread transition is required

Key specifications

• Connection A: 20 mm push-fit / barbed or socket compatible with 20 mm plastic/composite pipes
• Connection B: 3/4" internal (female) thread for mating with threaded fittings and valves
• Application: potable water and heating system pipe connections in residential and light-commercial settings
• Design: compact transition fitting suitable for confined installation spaces

How to use

Prepare the 20 mm pipe by cutting it squarely and deburring the end. Ensure the mating 3/4" threaded component is clean and free of old sealant or debris. Insert the pipe end into the 20 mm side of the fitting according to the pipe system’s connection method (push-fit, press, or socket as applicable) and tighten or secure per the system instructions. Apply appropriate thread sealing on the 3/4" male thread (such as PTFE tape or approved sealing compound) before assembling the joint to avoid leaks. Tighten the threaded connection to the manufacturer’s recommended torque or hand-tight plus specified turns if provided by the mating component supplier.

Usage recommendations

Verify material compatibility with the pipe and system media, and follow local plumbing codes. Use appropriate tools for pipe preparation and connection to ensure a durable, leak-free joint. Pressure-test the assembled system according to applicable standards before commissioning.
