KAN-therm Czwórnik Press 28 x 22 x 28 x 22 mm 90° through-tee fitting

KAN-therm Czwórnik Press 28 x 22 x 28 x 22 mm 90° through-tee fitting is a press-fit plumbing component designed to create a branch connection in press-system installations. It features two larger 28 mm ports and two smaller 22 mm ports arranged in a through-tee layout at a right angle, allowing fluid diversion between runs of metal-plastic or multilayer pipe where compatible press fittings are used.

Advantages

The fitting is manufactured for press-system assembly, providing a secure mechanical joint without the need for soldering or threaded connections. Its through-tee geometry with 90° branching enables compact routing of supply and return lines. Compatibility with commonly used press tools and metal-plastic or multilayer pipes simplifies installation and reduces joint preparation time.

Suitable for

• Creating branch connections in domestic and commercial plumbing systems
• Integrating supply and return lines in heating circuits
• Press-system installations using metal-plastic (multilayer) pipes
• Situations requiring a compact 90° branch in pipelines

When it may not be suitable

This through-tee is intended for use with compatible press systems and specific pipe materials; it may not be suitable for systems that require threaded, soldered, or welded joints. It is not designed for use with rigid metal-only pipes or non-compatible plastics unless the system documentation confirms compatibility.

Key specifications

• Connection configuration: through-tee with 90° branch
• Port diameters: two ports 28 mm and two ports 22 mm
• Connection type: press-fit compatible with press tools and rings
• Intended pipe types: metal-plastic or multilayer pipes where specified
• Application: plumbing and heating circuit branch connections

How to use

Prepare pipe ends by cutting square and deburring to the recommended insertion depth. Slide the appropriate press sleeve or ring over the pipe if required by the press system. Insert pipes fully into the fitting ports until they reach the internal stop. Use the matching press tool and jaw profile to make secure press connections at each port according to the press-system manufacturer's instructions. Verify each joint visually and, where applicable, with a recommended pressure test before putting the system into regular operation.

What to consider before purchase

• Confirm compatibility of the fitting with your press tool and jaw profile
• Verify that your pipes are metal-plastic or multilayer types suitable for press connections
• Ensure port sizes (28 mm and 22 mm) match your piping layout and required flow capacities
• Check system pressure and temperature requirements against the press-system specifications

Usage recommendations

Follow the KAN-therm press-system installation guidelines: use appropriate press tools, maintain clean and square pipe cuts, and perform pressure tests after installation. Where possible, plan runs to minimize unnecessary bends and ensure easy access for pressing and future maintenance.
