PVC Muffe Rohr Gerade Fitting Klebefittings ø20mm Bis 200mm Rohrverbinder Weiß

Match the inner diameter (ID) of the fitting to the outer diameter (OD) of your pipe. For example, a 20mm fitting is designed to accept a 20mm OD PVC pipe. If you are unsure, measure the outside of your existing pipe with calipers and select the closest matching size from the available options: 16, 20, 25, 32, 40, 50, 63, 75, 90, 110, 125, 160, or 200mm.

These PVC straight socket fittings are designed for cold-water and low-pressure applications such as irrigation, drainage, and general plumbing. Rigid PVC is typically rated up to around 60°C (140°F). For hot water supply lines or high-pressure systems, CPVC or other rated materials should be used. Always verify the pressure and temperature rating for your specific application before installation.

Use a standard PVC solvent cement (also called PVC glue or PVC primer and cement) compatible with rigid PVC pipe. Apply primer to both the pipe end and the socket interior, then apply cement and push the pipe firmly into the socket with a slight twist. Hold for 30 seconds and allow the joint to cure fully before pressurizing — typically 15–30 minutes for light handling and 24 hours for full pressure.

Yes. Rigid PVC is resistant to soil moisture, most common chemicals, and biological degradation, making it a widely used material for underground drainage, stormwater, and irrigation pipe systems. Ensure the solvent weld joint is fully cured before backfilling, and avoid sharp rocks or debris in direct contact with the fitting.

Each listing allows you to select both the inner diameter size and the number of pieces per order (1, 2, 3, 4, 5, 8, or 10). The price adjusts accordingly. This lets you order exactly the quantity needed for your project — whether it is a single repair piece or a multi-unit installation run — without purchasing more than required.

These fittings are compatible with metric PVC pipe of the matching inner diameter. However, pressure pipe and drainage pipe of the same nominal size can have different wall thicknesses and outer diameters depending on the standard (e.g., PN10, PN16, or DIN). Always verify that the fitting socket ID matches the OD of your specific pipe before cementing. If in doubt, test-fit the pipe dry before applying solvent cement.

No — this is a straight socket coupling, meaning both ends are the same diameter. It is designed to join two pipes of identical size. To connect pipes of different diameters, you would need a reducer coupling or a reducing bush. Check the HomeDIYer catalog for reducer fittings in the sizes you need.
