PPSU fitting KAN-therm 18x2.5 with G1/2" flange and internal thread (model 9019.46)

PPSU fitting KAN-therm 18x2.5 with G1/2" flange and internal thread is a polymer plumbing connector intended for joining pipes with an 18 mm outer diameter and 2.5 mm wall thickness to G1/2" threaded components. Manufactured from PPSU (polyphenylsulfone), the fitting offers high temperature and chemical resistance suitable for potable water and heating installations where material durability and compliance with plumbing requirements are needed.

Advantages

The PPSU material provides improved hydrolytic stability and resistance to repeated thermal cycling compared with many standard plastics. The integrated G1/2" flange and internal thread ensure a secure mechanical connection to standard threaded components while simplifying installation. Its dimensional compatibility with 18x2.5 pipe systems and stable material properties make it suitable for long-term use in closed water and heating circuits.

Suitable for

• Connecting 18x2.5 plastic pipes to G1/2" threaded valves and fittings
• Potable water distribution systems
• Residential and commercial heating systems
• Applications requiring chemical and thermal resistance of joining components

Key specifications

• Material: PPSU (polyphenylsulfone)
• Pipe compatibility: outer diameter 18 mm, wall thickness 2.5 mm
• Thread connection: internal G1/2" thread with flange
• Intended media: potable water, heating fluids
• Operating properties: high temperature and chemical resistance typical for PPSU

How to use

Prepare the 18x2.5 pipe by cutting squarely and deburring the cut end. Verify the pipe end is clean and free from contaminants before insertion. Insert the pipe into the fitting until it seats fully, and tighten the mating G1/2" threaded component to the recommended torque for the threaded connection type used, following the manufacturer's guidance for seals or tape where applicable. After assembly, pressurize and inspect the joint for leaks and proper mechanical engagement.

Usage recommendations

Use compatible seals or thread tape for the G1/2" connection to ensure leak-free joints. Avoid exposure to aggressive chemicals not recommended for PPSU and follow system temperature and pressure limits typical for PPSU components. Perform periodic inspection of threaded joints in heating circuits to confirm continued integrity.
