KAN-therm push-fit elbow PPSU 25x3.5 mm 9018.200 for plumbing and heating systems

KAN-therm push-fit elbow PPSU 25x3.5 mm is a 90° push-fit fitting made from PPSU (polyphenylsulfone) engineered for plumbing and heating systems. It is designed to connect 25 mm pipes with a 3.5 mm wall thickness without tools, offering a compact elbow solution for potable water and central heating installations. The product supports quick assembly and replacement while maintaining chemical and corrosion resistance typical of high-performance thermoplastic materials.

Advantages

The PPSU construction delivers high mechanical strength, good thermal stability and long-term resistance to hot water and steam exposure. The push-fit design enables fast, tool-free installation and secure, leak-resistant joints. Its suitability for potable water ensures compliance with installations where water quality must be preserved, while compatibility with heating systems makes it versatile for mixed applications. The compact 90° geometry helps minimize occupied space and simplifies routing in tight areas.

Suitable for

• Domestic and commercial potable water distribution
• Central heating pipework and radiator connections
• Repairs and retrofit work where tool-free assembly is preferred
• Tight installations and confined plumbing spaces

Key specifications

• Fitting type: 90° elbow (push-fit)
• Material: PPSU (polyphenylsulfone)
• Connection method: push-fit (tool-free)
• Pipe compatibility: 25 mm nominal diameter with 3.5 mm wall thickness
• Applications: potable water and central heating systems
• Corrosion resistance: suitable for long-term water exposure

How to use

Ensure pipes are cut squarely and deburred before insertion. Verify the pipe outer diameter and wall thickness match the required 25x3.5 mm specification. Insert the pipe into the push-fit elbow until it reaches the internal stop; a tactile or audible click may confirm engagement. For hot-water heating systems follow system-specific filling and pressurization procedures and perform a visual and pressure test to confirm leak-free joints after installation.

Usage recommendations

Store fittings protected from direct sunlight and prolonged UV exposure. Use only pipes that meet the specified 25x3.5 mm dimension and suitable materials recommended for potable water and heating. For installations involving higher temperatures or special fluids, consult system design guidelines and applicable standards.
