Measure the outer diameter (OD) of your existing PVC pipe, then match it to the corresponding nominal size. For example, a pipe with a 25mm OD typically uses a 20mm nominal fitting. If you are unsure, check the pipe markings or use a calliper. The inner diameter listed in the variant options refers to the nominal pipe size the fitting is designed to accept.

Use a PVC solvent cement (also called PVC glue or solvent weld adhesive) that is compatible with rigid PVC pressure pipe. Clean and dry both the pipe end and the fitting socket before applying a thin, even coat of cement. Join immediately and hold for 30–60 seconds. Allow the joint to cure fully before pressurising — typically 24 hours at room temperature.

No. These fittings are rated for cold water applications up to approximately 60°C (140°F) at reduced pressure. They are not suitable for continuous hot water supply, central heating, or steam systems. For hot water applications, CPVC or copper fittings are recommended.

Yes. Rigid PVC is resistant to corrosion and most chemicals found in treated water, making these couplings well-suited for garden irrigation manifolds, drip systems, and pool or pond plumbing. For prolonged direct sunlight exposure, consider painting or lagging the pipe and fittings, as extended UV exposure can cause gradual surface degradation over many years.

A correctly made solvent weld joint is typically as strong as — or stronger than — the pipe itself. The solvent cement chemically fuses the pipe and fitting into a single homogeneous unit. Provided the surfaces are clean, dry, and the cement is applied correctly, the joint will withstand the full PN10 (10 bar) working pressure rating of the fitting.

No. These are solvent weld fittings designed exclusively for rigid PVC pressure pipe conforming to DIN 8061 / ISO 1452. They are not compatible with HDPE, ABS, CPVC, or copper pipe. For connecting PVC to other pipe materials, use appropriate transition fittings or compression adaptors.

Count the number of straight pipe joins in your layout — each join requires one coupling. We offer packs of 1, 2, 3, 4, 5, 8, or 10 pieces so you can order the exact quantity needed. Ordering a small surplus (1–2 extra) is advisable to allow for any practice cuts or installation errors.

No — solvent weld joints are permanent once cured. If a joint is incorrectly made, the affected section of pipe must be cut out and replaced with a new fitting and pipe offcut. This is why it is important to dry-fit all components before applying cement, and to work methodically through the assembly.
