PVC Gerade Verschraubung Rohrverbinder Klebemuffe Fittings DN15-DN40 20-50mm

Match the connector's inner diameter to your pipe's outer diameter. DN15 fits 20mm OD pipe, DN20 fits 25mm OD, DN25 fits 32mm OD, DN32 fits 40mm OD, and DN40 fits 50mm OD pipe. If you are unsure, measure the outside of your existing pipe with calipers before ordering.

Use a standard PVC solvent cement (also called PVC glue or solvent weld adhesive) rated for your pipe's application — water supply, drainage, or irrigation. Apply primer first if required by local codes, then apply cement to both the pipe end and the socket, push together with a slight twist, and hold for 30 seconds. Allow full cure time before pressurizing.

These PVC fittings are rated for cold water service up to approximately 60°C (140°F). They are not recommended for continuous hot water supply lines above that temperature. For hot water applications, consider CPVC or other heat-rated fittings.

The Blue variants are commonly used in potable water irrigation and supply lines. Please verify local regulatory compliance for your specific installation before use in drinking water systems, as requirements vary by region.

The color difference is primarily for identification and system organization. White and Grey are typically used in drainage, waste, and general plumbing runs. Blue is conventionally associated with cold water supply and irrigation lines. All three colors share the same PVC material and solvent-weld connection method.

Yes. Rigid PVC is resistant to soil corrosion and moisture, making it suitable for buried installations. Ensure the solvent weld joint is fully cured before backfilling, and use bedding material free of sharp rocks that could stress the pipe or fittings.

These fittings follow metric DN sizing standards. The approximate imperial equivalents are: 20mm ≈ ¾", 25mm ≈ 1", 32mm ≈ 1¼", 40mm ≈ 1½", 50mm ≈ 2". Always verify by measuring your pipe's actual outer diameter rather than relying solely on nominal size labels.
