KAN-therm press fitting Złączka GZ Steel Press 35 x R5/4" (model 6240157)

The KAN-therm press fitting Złączka GZ Steel Press 35 x R5/4" is a steel transition fitting engineered to connect a 35 mm plastic or metal pipe to a R5/4" (1¼") threaded outlet. The fitting provides a pressed, leak-resistant joint on the pipe side and a standard male threaded connection compatible with valves, adapters and other threaded components. It is intended for use in plumbing and heating systems where a durable metal-to-thread interface is required and where press-connection technology is preferred for speed and reliability.

Advantages

This steel press fitting combines the strength and corrosion resistance of steel with the convenience of a press assembly on the pipe side and a conventional threaded connection on the outlet side. The pressed connection delivers quick, repeatable installation without soldering or welding, while the threaded end allows connection to commonly used valves and accessories. The design supports stable mechanical performance in residential and commercial plumbing and heating applications.

Suitable for

• Joining 35 mm plastic or metal pipe to a R5/4" (1¼") threaded valve or accessory
• Domestic and commercial heating systems
• Plumbing installations requiring a mixed press-to-thread transition
• Renovation projects where replacing sections of pipeline with threaded components is necessary

Key specifications

• Material: steel construction suitable for press joining on the pipe side
• Pipe connection diameter: 35 mm press connection
• Threaded outlet: R5/4" (1¼") male thread for valves and fittings
• Connection type: press connection on pipe side and threaded connection on outlet side
• Application: plumbing and heating systems for potable water and heating circuits (where steel fittings are appropriate)

How to use

Prepare the pipe end by cutting square and deburring inside and outside. Insert the pipe fully into the press fitting until it seats against the stop. Verify alignment and use the correct press tool and jaw size for a 35 mm press connection, following the tool manufacturer’s instructions. After pressing, inspect the joint visually to ensure a complete press profile. Attach the threaded component by applying appropriate thread sealant or tape to the male thread if required by the system, and tighten to the specification of the connected device or valve.

Usage recommendations

Use compatible press tools and jaws specifically rated for 35 mm steel press fittings, and follow relevant plumbing and heating standards for pressure testing and installation. Consider corrosion protection measures and verify material compatibility with the fluid and system temperatures prior to installation.
