PPSU press tee KAN-therm 18x2.5 / 25x3.5 / 18x2.5 model 9018.240

KAN-therm PPSU press tee model 9018.240 is a three-way plastic fitting designed for creating T-connections in press-fit piping systems. Manufactured from PPSU, the fitting combines high temperature resistance and chemical stability with a compact geometry that fits potable water and heating installations. The tee provides two aligned runs and one branch in sizes 18x2.5 mm and 25x3.5 mm suitable for press-connection technology and standard polymer piping dimensions.

Advantages

The PPSU material offers elevated thermal and chemical resistance compared with standard thermoplastics, ensuring long-term dimensional stability under operating temperatures common in domestic hot water and heating systems. The press-style ends enable fast and reliable installation with compatible press tools and jaws, reducing assembly time and mechanical stress compared with threaded or glued joints. Its compact tee form factor minimizes space requirements in manifolds, risers and concealed installations while maintaining flow efficiency for typical residential and light-commercial systems.

Suitable for

• Potable hot and cold water distribution systems
• Domestic and small commercial heating circuits
• Concealed installations, manifolds and compact utility spaces
• Retrofit projects where press connections are preferred

Key specifications

• Material: PPSU (polyphenylsulfone) offering thermal and chemical resistance
• Connection type: press-fit ends compatible with press-connection systems
• Branch dimensions: 18 x 2.5 mm and 25 x 3.5 mm (outer diameter x wall thickness)
• Configuration: tee with two aligned runs and one branch
• Application temperature range suitable for potable water and heating systems (refer to system design limits)

How to use

Select compatible press tools and jaws specified for PPSU press fittings and ensure the pipe ends are cut squarely and deburred. Mark insertion depth on the pipes, push pipes fully into the fitting until the stop, and perform the press operation according to the press tool manufacturer's instructions. After pressing, visually inspect the connection and, where required by local practice, perform pressure testing of the system before commissioning.

Usage recommendations

Use only press jaws and certified seals approved for PPSU fittings and follow the installation guidelines of both the press tool and piping system manufacturer. Avoid exposure to aggressive chemicals beyond the material's specified resistance and verify operating temperatures and pressures against system design criteria.
