Press-fit reducing coupling Comap 40x3.5 → 32x3 PPSU (model 9240W4032)

Comap Złączka redukcyjna, zaprasowywana (PPSU) 40x3,5 - 32x3 is a press-fit reducing coupling made from PPSU (polyphenylsulfone) designed for reliable connections in plumbing and heating systems. The fitting provides a transition between 40x3.5 mm and 32x3 mm pipe dimensions, delivering a compact solution for downsizing pipe runs where space or system design requires a smaller diameter.

Advantages

The PPSU material offers high mechanical strength, chemical resistance and durability at a range of operating temperatures. As a press-fit coupling, it enables leak-resistant joints when installed with compatible pressing tools and rings, reducing installation time compared with traditional soldered or threaded connections. Its compact reducing design simplifies pipe routing and minimizes the need for additional adaptors.

Suitable for

• Domestic and commercial hot and cold water distribution systems
• Heating circuits and connection of radiators or manifolds
• Retrofit projects where pipe diameter must be reduced
• Areas requiring corrosion-resistant plastic fittings

Key specifications

• Material: PPSU (polyphenylsulfone)
• Connection type: press-fit (zaprasowywana)
• Inlet dimension: 40 x 3.5 mm
• Outlet dimension: 32 x 3.0 mm
• Design: reducing coupling for transition between pipe diameters

How to use

Ensure pipes are cut square, deburred and cleaned before assembly. Slide the correct pressing sleeve or ring onto the pipe where required, insert the pipe ends fully into the coupling until they reach the internal stop, and perform a press operation with a compatible pressing tool according to the tool and sleeve manufacturer’s guidance. Verify each pressed connection visually and, where applicable, test the system pressure to confirm leak-free joints.

Usage recommendations

Use this PPSU press reducing coupling only with compatible press-fit sleeves and tools recommended for plastic fittings; follow local plumbing codes and the pipe manufacturer’s temperature and pressure limits. Regularly inspect installed fittings during commissioning and maintenance to ensure continued integrity.
