Match the fitting size to the outer diameter (OD) of your pipe. For example, a 25 mm fitting accepts pipe with a 25 mm OD. Measure your existing pipe with calipers rather than relying on nominal labels, as pipe schedules can vary. If you are between sizes, always size up and use a reducer coupling rather than forcing an undersized fitting.

No. These are solvent-weld (glue-type) fittings designed exclusively for use with metric solvent-weld PVC pipe. They are not compatible with push-fit (e.g. Speedfit/John Guest), BSP/NPT threaded fittings, CPVC, or ABS pipe without an appropriate transition adapter. Using incompatible systems risks joint failure and leaks.

A correctly made solvent-weld joint chemically fuses the fitting socket and pipe spigot into a single homogeneous structure. When cured, the joint is typically as strong as or stronger than the pipe wall itself. This makes it one of the most reliable connection methods for permanent PVC installations. Cure time varies by cement type and ambient temperature — always follow the cement manufacturer's instructions before pressurising the system.

PVC is inherently corrosion-resistant and performs well underground and in damp environments. For above-ground outdoor use, prolonged direct UV exposure can cause surface chalking over time; painting with a water-based exterior paint or wrapping with UV-protective tape is recommended for long-term outdoor installations. For underground use, ensure the pipe and fittings are rated for the burial depth and soil conditions of your project.

The colour difference is primarily for system identification rather than a change in material properties. White is the most common general-purpose colour for plumbing and above-ground pipework. Blue is widely used to identify cold-water mains in many plumbing conventions. Grey is commonly associated with drainage, conduit, and industrial pipework. Choose the colour that matches your existing system or local convention — all three colours are the same rigid PVC material.

Use a Muffe (coupling) to join two straight pipe lengths. Choose a 45° or 90° elbow to change pipe direction — 45° elbows create a gentler bend with lower flow resistance, while 90° elbows make sharp right-angle turns. A 90° tee (T-Stück) splits or combines flow at a branch. Multi-way connectors (3-way through 6-way) are used for manifold or distribution points. The Kugelhahn (ball valve) provides inline shut-off for zone isolation or service access. If you are unsure, contact us with your system diagram and we can advise.

Ball valves are primarily designed for full open / full closed operation. While they can be partially opened to throttle flow, sustained partial-open operation can cause accelerated wear on the ball seat and is not recommended for precise flow regulation. For variable flow control, a dedicated gate valve or needle valve is more appropriate. Use the ball valve for clean on/off isolation of zones or service points.
