PVC Reduzierstück Muffe Rohr Fitting Klebefittings Lang Konisch I.D. 20mm-63mm

Measure the outer diameter (OD) of each pipe you are joining. For standard metric PVC pressure pipe, the fitting's inner diameter (ID) is sized to accept the pipe's OD with a close slip fit. For example, a 40×25mm reducing socket accepts a 40mm OD pipe on the large end and a 25mm OD pipe on the small end. If you are unsure, bring a short pipe sample to compare, or contact us to confirm compatibility before ordering.

A long conical socket has an extended taper that creates a larger bonded surface area between the fitting and the pipe. This results in a stronger joint that better resists axial pull-out, vibration, and water hammer compared to a short-pattern reducer. Long conical sockets are preferred in pressure systems, buried runs, and anywhere the joint cannot be easily accessed for repair.

No. These fittings are manufactured from standard rigid PVC, which is rated for cold-water service only (typically up to around 60°C / 140°F at low pressure, but working pressure drops significantly with temperature). For hot-water supply lines, CPVC or PP-R fittings are required. Do not use these in steam, compressed-air, or high-temperature applications.

Use a PVC-compatible primer (cleaner) followed by a medium- or heavy-bodied PVC solvent cement rated for the pipe pressure class you are working with. Apply primer to both the pipe end and the fitting socket, then apply cement to both surfaces and assemble with a quarter-turn twist. Hold for 30 seconds and allow the joint to cure per the cement manufacturer's instructions before pressurizing. Do not use ABS or CPVC cement on PVC fittings.

Yes. Rigid PVC is widely used in garden irrigation manifolds, drip systems, and pool/spa plumbing because it resists chlorine, UV (when painted or buried), and common fertilizer solutions. Confirm that the working pressure of your system does not exceed the fitting's rated pressure for the selected size, and ensure all joints are fully cured before filling the system.

The color difference is cosmetic — both white (Weiß) and gray (Grau) variants are made from the same rigid PVC compound and carry equivalent mechanical and chemical properties. White fittings are common in visible indoor plumbing and pool applications; gray is standard in many European pressure-pipe systems and outdoor irrigation. Choose the color that matches your existing pipe run or local convention.

For a single repair or connection point, a quantity of 1 is sufficient. For a full irrigation manifold or multi-branch plumbing rough-in, packs of 5 or 10 offer a lower per-unit cost and ensure you have spares on hand if a joint needs to be cut out and redone. Solvent-cement joints are permanent, so having at least one extra fitting per size is a practical precaution on larger projects.
