Copper press reduction fitting KAN-therm Inox Press 42x15 mm (reducing nipple)

The KAN-therm Inox Press reduction fitting 42x15 mm (reducing nipple) is a stainless-steel compatible press connection designed to join a 42 mm pipeline to a 15 mm line within press-installation systems. It provides a compact mechanical transition between different pipe diameters for plumbing and heating installations where durable, leak-resistant joints are required. The fitting is intended for use with compatible Inox Press press tools and press sleeves to create permanent connections without soldering or threaded joints.

Advantages

This reduction fitting offers a reliable pressed joint that reduces installation time compared to soldered or threaded transitions. Made to be compatible with Inox Press systems, it ensures consistent joint quality when used with appropriate press tools. The compact design saves space in tight installation areas and provides corrosion resistance characteristic of stainless-steel compatible press components. The single-piece reducing nipple minimizes additional sealing elements and simplifies inventory management for mixed-diameter systems.

Suitable for

• Joining a 42 mm stainless-steel compatible press pipe to a 15 mm line in plumbing systems
• Reducing diameter in residential and commercial heating installations
• Retrofit work where a larger distribution main transitions to smaller branch lines
• Applications requiring press-fit connections without soldering or welding

Key specifications

• Connection type: press-compatible reducing nipple for Inox Press systems
• Material compatibility: stainless-steel compatible press connection
• Dimensions: 42 mm to 15 mm diameter reduction
• Application: plumbing and heating press-installation systems
• Installation method: press-fit using matching Inox Press tooling and press sleeves

How to use

Select the appropriate press tool and press sleeves specified for Inox Press compatible fittings and verify that the pipe ends are cut square, deburred and free from contaminants. Insert the 15 mm and 42 mm pipes fully into the respective ends of the reducing nipple, ensuring correct insertion depth. Position the press jaw concentrically over the press sleeve area and perform the press operation in accordance with the press tool manufacturer’s instructions. After pressing, inspect the pressed joints visually and, where required, perform a pressure test in line with system standards to confirm leak-free installation.

Usage recommendations

Use only press sleeves and tools approved for Inox Press-compatible stainless-steel systems. Store fittings in a dry environment and protect pipe ends and fitting surfaces from damage prior to assembly. Follow local plumbing codes and perform pressure testing after installation to verify joint integrity.
