KAN-therm push tee PPSU plumbing fitting 25x3.5/25x3.5/18x2.5

The KAN-therm push tee PPSU plumbing fitting 25x3.5/25x3.5/18x2.5 is a three-branch connector designed for push-fit plumbing installations. Manufactured from PPSU, the fitting provides chemical and thermal resistance suitable for potable water and heating systems where pipe dimensions match 25x3.5 mm and 18x2.5 mm. The push connection enables tool-free assembly and fast integration into existing polybutylene or polyethylene piping networks that follow the same dimensional standards.

Advantages

This PPSU push tee offers corrosion resistance, dimensional stability at elevated temperatures, and a smooth internal passage to minimise flow disruption. The push-fit design reduces installation time by eliminating the need for soldering, adhesives or complex tools, while the material properties of PPSU deliver long-term durability in contact with hot water and common plumbing chemicals. The fitting is compatible with standard push-fit seals to ensure leak-tight joints when installed correctly.

Suitable for (tasks / use cases)

• Connecting three pipeline branches in potable water distribution systems
• Branching supply lines in heating circuits and radiator feeds
• Retrofit and new-build installations using compatible 25x3.5 mm and 18x2.5 mm pipes
• Tool-free assembly applications where rapid installation is required

Key specifications

• Material: PPSU (polyphenylsulfone)
• Connection type: push-fit (push-to-connect)
• Pipe connection sizes: two outlets 25 x 3.5 mm, one branch 18 x 2.5 mm
• Application: potable water and heating systems (where compatible with pipe material and dimensions)
• Internal design: smooth bore to reduce flow resistance

How to use

Ensure pipe ends are cut square, deburred and free of contaminants before insertion. Verify that pipe outer dimensions match 25x3.5 mm and 18x2.5 mm as required. Push the pipe firmly into the fitting until it seats against the stop and the retaining mechanism engages; you should feel a positive click or resistance indicating full insertion. For removal or repositioning, follow the pipe system manufacturer's guidance and use the recommended release tool if applicable. After assembly, perform a pressure test according to applicable plumbing standards to confirm leak-tight joints.

Usage recommendations

Use compatible pipe materials and the recommended seals; avoid exposure to solvents or aggressive chemicals not specified for PPSU. Observe temperature and pressure ratings of the overall system and follow local plumbing codes during installation and testing.
