KAN-therm Steel Press extension 18x18 mm — model 1509080004

KAN-therm Steel Press extension 18x18 mm — model 1509080004 is a press-fit coupling designed to join or extend 18×18 mm steel pipe runs in plumbing and heating systems. The fitting is intended for use with press connection tools and compatible press jaws, creating a secure mechanical joint without welding or threads. It is manufactured for compact installations, repair work and system extensions where a reliable steel press connection is required.

Advantages

The press extension provides a fast, repeatable connection that reduces installation time compared with traditional threaded or welded joints. It delivers a mechanically robust seal that resists axial and radial loads typical for domestic and light commercial plumbing and heating circuits. The compact 18x18 mm form factor is suitable for confined spaces and allows straightforward replacement or extension of existing steel pipe sections.

Suitable for

• Connecting or extending 18×18 mm steel piping in residential heating systems
• Repairing damaged sections of steel pipework
• Compact plumbing installations with limited access
• Mechanical press-joining applications using compatible press tools

Key specifications

• Material: steel suitable for press-fit connections
• Connection type: press-fit coupling for 18×18 mm tubing
• Size: 18 mm outer diameter by 18 mm outer diameter (end-to-end)
• Application: plumbing and heating systems
• Installation method: press technology with compatible jaws/tools

How to use

Prepare pipe ends by cutting square and removing burrs and debris. Ensure the pipes and fitting are clean and free of corrosion, oil and dirt. Position the fitting onto the prepared 18×18 mm pipe ends so that the ends reach the marked insertion depth. Use the correct press tool and jaw size recommended for 18 mm steel press fittings and perform the press cycle according to the tool manufacturer's instructions. Verify each press visually and, where applicable, by the tool’s feedback or measurement method to ensure a complete seal.

Usage recommendations

Use only compatible press tools and jaws specified for steel 18 mm press fittings. Inspect pipe surfaces before assembly and follow local regulations and system design requirements for pressure testing and corrosion protection. For installations exposed to aggressive environments or where additional protection is required, consider appropriate coatings or insulation applied after making the press connection.
