Transparent PVC Rohr Übergangsnippel Klebemuffe x Außengewinde Fittings 20-63mm

Match the socket end to your pipe's outer diameter (OD): 20 mm, 25 mm, 32 mm, 40 mm, 50 mm, or 63 mm. The thread size listed (e.g., ½", ¾") refers to the BSP nominal thread on the male end, which corresponds to the same nominal pipe size. If you are unsure, measure your existing pipe OD with calipers before ordering.

The threaded spigot uses BSP (British Standard Pipe) parallel thread, conforming to ISO 228 / DIN 259. This is the most common thread standard for plumbing fittings in Europe and many other regions. If your valve or pump uses NPT (National Pipe Thread, common in North America), these fittings are not directly compatible — please verify your thread standard before purchasing.

Use a standard PVC solvent cement (also called PVC glue or Klebstoff). Clean and dry both the pipe end and the socket interior, apply a thin, even coat of solvent cement to both surfaces, push the pipe firmly into the socket with a slight twist, and hold for 30 seconds. Allow the joint to cure fully before pressurizing — typically 15–30 minutes for initial set and 24 hours for full cure, depending on ambient temperature and humidity.

PVC is widely used in cold potable water distribution. However, suitability for drinking water depends on the specific compound formulation and applicable local regulations. Please contact us to confirm whether this product carries the certifications required in your region before using it in a potable water application.

Rigid PVC offers good resistance to chlorinated water, dilute acids, alkalis, and many common irrigation chemicals and fertilizers. It is not recommended for use with concentrated solvents, aromatic hydrocarbons, or highly oxidizing acids. For specific chemical compatibility, consult a PVC chemical resistance chart or contact us with your application details.

These fittings are rated for cold and ambient-temperature water systems, typically up to 60 °C (140 °F). Working pressure decreases significantly as temperature rises — at 60 °C, the pressure rating may be reduced to 25–40% of the rated cold-water value. For hot water or steam applications, a CPVC or metal fitting is recommended instead.

This depends on your layout. A single pump connection or filter bypass typically requires 1–2 fittings. A manifold or multi-branch irrigation system may need 5 or more. We offer packs of 1, 2, 3, 5, and 10 pieces — ordering a slightly larger pack is often more economical per unit and ensures you have spares on hand for future repairs.
