PVC Weiß Reduzierstück Muffe Rohr Fitting Klebefittings Ø25*20mm~Ø160*125mm

The size designation follows the format Ø[larger OD] × [smaller OD] in millimetres — for example, Ø50×32 mm means the larger socket accepts 50 mm OD pipe and the smaller spigot end connects to 32 mm OD pipe. Measure the outer diameter of both pipes you are joining and select the matching size from the variant dropdown.

Yes. The socket and spigot dimensions conform to DIN 8063 / ISO 727 tolerances, which are the standard for metric rigid PVC pressure pipe sold across Europe and many other markets. Always dry-fit before cementing to confirm the interference fit is correct for your specific pipe batch.

Use a PVC-specific solvent cement rated for pressure pipe (e.g., conforming to ASTM D2564 or equivalent). Apply a thin, even coat to both the pipe spigot and the fitting socket, push together with a slight twist, and hold for 30 seconds. Allow the joint to cure fully — typically 15 minutes before handling and 24 hours before pressurising — following the cement manufacturer's instructions.

These fittings are manufactured from rigid uPVC. Suitability for potable (drinking) water depends on local regulations and the specific certification required in your jurisdiction. For non-potable applications such as irrigation, pool plumbing, and grey-water systems, they are well suited. Contact us to confirm certification details if potable-water compliance is required.

A correctly made solvent-weld joint chemically fuses the pipe and fitting into a single homogeneous structure. When fully cured, the joint typically has a burst strength equal to or greater than the pipe wall itself, making it the strongest connection method for rigid PVC systems. Threaded joints rely on mechanical compression and are more prone to stress cracking; push-fit joints are convenient but rated for lower pressures.

Rigid uPVC has inherent resistance to UV degradation compared to many other plastics, but prolonged direct sunlight exposure over many years can cause surface chalking and gradual embrittlement. For permanently exposed outdoor installations, painting the fittings with a water-based exterior paint or wrapping with UV-protective tape is recommended to extend service life.

Each size and quantity combination is a separate variant. To order multiple sizes, simply add each required variant to your cart individually. If you need a large project quantity across many sizes, contact us — we may be able to assist with a consolidated order.
