KAN-therm transition fitting PUSH x PRESS 18x2.5 / 16x2 K-902718 for plumbing connections

KAN-therm transition fitting PUSH x PRESS 18x2.5 / 16x2 K-902718 is a compact adapter designed for reliable transitions between two common pipe connection systems in plumbing and heating installations. One end uses a mechanical PUSH connection suitable for push-fit polymer or composite pipes with 18x2.5 mm dimensions, while the opposite end provides a PRESS (crimp) connection for 16x2 mm metal or multilayer pipes. The fitting facilitates secure hydraulic continuity between different pipe materials and diameters in potable water and heating networks.

Advantages

This KAN-therm transition fitting combines two connection technologies in a single component, reducing the need for additional adapters and streamlining installation work. The PUSH side allows fast, tool-free insertion and immediate mechanical retention, while the PRESS side offers a permanent crimped joint that is compatible with standard pressing tools. The compact form factor supports installation in confined spaces and helps maintain system integrity when connecting dissimilar pipes.

Suitable for

• Transitions between polymer/composite 18x2.5 mm pipes and 16x2 mm metal or multilayer pipes
• Potable water distribution systems
• Residential and commercial heating circuits
• Repair work where a change of connection type is required

Key specifications

• Connection types: PUSH on one end, PRESS (crimp) on the other
• Pipe compatibility: 18 x 2.5 mm (PUSH side) and 16 x 2.0 mm (PRESS side)
• Application: potable water and heating systems
• Installation environment: indoor plumbing and heating installations
• Construction: compact transition adapter for limited spaces

How to use

Prepare both pipes by cutting squarely and deburring the inner and outer edges. For the PUSH side, insert the 18x2.5 mm pipe fully into the fitting until it seats and the mechanical retention engages; verify by pulling gently to confirm a secure hold. For the PRESS side, position the 16x2 mm pipe into the fitting and perform a press/crimp operation using a compatible pressing tool and appropriate jaws, following the tool manufacturer's instructions. After joining, inspect both connections for correct insertion depth and proper press quality before placing the system into service.

Usage recommendations

Use the fitting only with pipes and tools that match the specified dimensions and connection methods. Ensure compliance with local plumbing codes and pressure/temperature ratings of the overall system. When working with potable water installations, verify materials and procedures meet applicable hygiene standards.
