5-63mm Schlauchtülle PVC Klebefittings Druck Wasser Rohr Fittings Weiß Blau Grau

Match the outer diameter (OD) of the fitting to your existing PVC pipe socket size, and match the barb OD to the inner diameter (ID) of your flexible hose. For example, a 20 mm fitting fits a 20 mm PVC pipe socket; the barb end should slide snugly into your hose so the ribs grip the inner wall. If in doubt, measure your hose ID and pipe socket ID before selecting a variant.

The insertion length is the depth of the barbed end that inserts into the flexible hose. A longer insertion length provides more grip surface and is recommended for higher-pressure or vibration-prone applications. Shorter lengths suit low-pressure or space-constrained installations.

PVC is widely used in water supply systems. However, suitability for potable water depends on local regulations and the specific grade of PVC. Please verify compliance with your local plumbing code before use in drinking water applications. Contact us to confirm if you need documentation.

When correctly applied with a compatible PVC solvent cement (primer + cement), the glued joint chemically fuses the fitting and pipe into a single piece. The bond typically exceeds the burst pressure of the pipe itself. Allow full cure time (typically 24 hours at room temperature) before pressurizing the system.

Rigid PVC is inherently corrosion-resistant and unaffected by most water-treatment chemicals including chlorine. For prolonged outdoor UV exposure, consider painting or insulating the fittings, as unprotected PVC can become brittle over years of direct sunlight. Grey and White variants are commonly used in above-ground outdoor plumbing with appropriate UV protection.

The barbed end is compatible with flexible PVC hose and can also work with soft polyethylene or rubber hose of matching inner diameter. The key is that the hose ID should match the barb OD closely so the ribs create a secure grip. For high-pressure applications, a hose clamp over the barb is recommended regardless of hose material.

Color coding is a practical tool in multi-circuit plumbing systems — for example, Blue for cold water, Grey for drainage or recirculation, and White for general supply lines. Using different colors makes it easy to trace circuits during maintenance without labeling every pipe. All three colors share the same dimensions and performance characteristics.
