Measure the outer diameter (OD) of your existing pipe with calipers or a tape measure. For standard metric PVC pressure pipe, the coupling's listed inner diameter corresponds to the pipe's nominal OD. For example, a 25mm coupling fits pipe with a 25mm outer diameter. If you are unsure, bring a short pipe sample to compare before ordering.

Rigid PVC is widely used in cold potable water systems. However, suitability for drinking water depends on the specific certification required in your region. Please contact us to confirm whether the batch you are ordering carries the relevant local approval (e.g. WRAS, NSF/ANSI 61) before use in a potable water application.

Use a PVC solvent cement rated for the pipe class and application (e.g. a medium-bodied all-purpose PVC cement for pressure pipe, or a heavy-bodied cement for larger diameters above 63mm). Always apply a PVC primer first to clean and soften the bonding surfaces. Follow the cement manufacturer's cure time before pressurising the joint — typically 15 minutes for handling and 24 hours for full pressure.

Yes. Rigid PVC is resistant to soil moisture and most ground chemicals, making solvent weld couplings a standard choice for buried irrigation laterals and drainage runs. Ensure the trench backfill is free of sharp stones that could stress the pipe wall, and verify the pressure rating is appropriate for the depth and application.

When correctly prepared and bonded, a solvent weld joint chemically fuses the fitting and pipe into a single homogeneous structure. The joint area typically reaches or exceeds the tensile strength of the pipe wall itself, meaning a properly made joint will not be the weak point in the system. Joint failure is almost always the result of insufficient cure time, contaminated surfaces, or mismatched pipe and fitting dimensions.

Yes — a straight coupling is one of the most common tools for PVC pipe repair. Cut out the damaged section cleanly with a pipe cutter or fine-tooth saw, deburr both cut ends, then use two couplings and a short replacement pipe section to bridge the gap. Ensure the replacement pipe matches the original pipe's outer diameter and pressure class.

These couplings are designed for rigid metric PVC pipe. Flexible PVC (e.g. pond or pool hose) has a different wall thickness and may not seat correctly in the socket. CPVC requires its own dedicated solvent cement and fittings. Using incompatible materials risks a weak or leaking joint. Contact us if you need to confirm compatibility with a specific pipe type.
