PVC 90° Winkel Reduzierstück Rohrverbinder Reduzierstück Muffe Fittings 20-110mm

Measure the outer diameter (OD) of both pipes you need to connect. The larger socket of the fitting should match your inlet pipe OD, and the smaller socket should match your outlet pipe OD. For example, if you are connecting a 40mm pipe turning into a 25mm pipe at 90°, select the 40×25mm variant. Always verify the pipe OD against the fitting socket size before applying solvent cement.

PVC reducing elbows are widely used in both low-pressure supply lines and gravity-fed drainage systems. For pressure applications, confirm the pressure rating of the specific size variant with us before installation, as wall thickness and rated pressure vary by size. For standard household drainage and vent lines, these fittings are a direct fit.

Yes. Rigid PVC does not rust, corrode, or degrade from soil contact or moisture exposure under normal conditions. It is suitable for buried drainage runs, outdoor irrigation systems, and damp environments such as crawl spaces. Avoid prolonged direct UV exposure without protective coating, as unshielded PVC can become brittle over many years of sunlight exposure.

Use a standard PVC solvent cement (PVC glue) rated for the pipe schedule and application type. For best results, clean both the pipe end and fitting socket with PVC primer before applying cement. Work quickly — solvent cement sets within seconds and cures to full strength within 24 hours. Do not use push-fit or compression connectors with these socket-end fittings.

A reducing elbow combines two functions into one fitting, which means fewer joints in your system. Every additional joint is a potential leak point and adds labor time. In tight spaces — such as under a sink cabinet or inside a wall cavity — a single compact reducing elbow also takes up significantly less room than two fittings joined in series.

For a single repair or connection point, the 1-piece option is sufficient. For renovation projects with multiple branch connections, ordering 3–5 pieces of the same size is common practice and reduces per-unit cost. Contractors and trade buyers typically select the 10- or 20-piece packs for the best value per fitting. All quantity options are available for each size combination.

These fittings are sized to metric PVC pipe standards (e.g., 25mm, 32mm, 40mm, 50mm, 63mm, 75mm, 90mm, 110mm). Imperial pipe sizes (e.g., 1", 1¼", 1½") have different outer diameters and may not seat correctly in metric sockets. If you are working with imperial pipe, please contact us to confirm compatibility before ordering.
