PVC Water Stop Joint Waterproof Sleeve Fittings Straight Drainage 50 75 110mm

Match the sleeve size to your pipe's nominal outer diameter: choose 50mm for ~50mm OD drainage pipe (~2 in), 75mm for ~75mm OD (~3 in), and 110mm for ~110mm OD (~4 in). Note that drainage pipe and pressure pipe carry different actual ODs at the same nominal size — always measure your pipe's outer diameter with calipers before ordering.

These fittings are designed for drainage and waste-line applications, which operate at low or zero internal pressure. They are not rated for pressurised water supply lines. For pressure pipe repairs, use fittings specifically rated to your system's working pressure.

The integrated rubber water stop ring is designed for long-term service in drainage conditions. In typical buried or indoor drainage applications, the ring should not require routine replacement. If the fitting is removed and reinstalled, inspect the ring for deformation or cracking before reuse and replace if any damage is visible.

The sleeve's rubber compression seal can form a watertight joint against both PVC and ABS pipe surfaces provided the pipe OD falls within the fitting's tolerance range. Confirm the actual OD of your ABS pipe matches the nominal size of the sleeve before installation.

Yes. Because the seal is achieved through mechanical compression rather than solvent cement, the fitting can be installed on pipes that are damp on the outside. The pipe surface should be free of standing water and debris at the contact zone to ensure the rubber ring seats evenly.

A single straight joint repair typically requires 1 piece. If you are repairing a section of pipe by cutting out a damaged length and inserting a replacement spool, you will need 2 sleeves — one at each end of the repair section. Order the 5-piece pack if you have multiple joints to seal in the same project.

No solvent cement is required for the sleeve's primary seal function. The rubber water stop ring provides the watertight barrier through compression. Some installers apply a thin bead of compatible PVC sealant to the pipe surface as an additional precaution in high-moisture environments, but this is not mandatory for standard drainage use.
