PVC Pipe End Cap Cover Stop Plug 20 25 32 40 50 63 75 90 110mm Pipe Fittings

Match the cap size to your pipe's nominal outer diameter (OD). For example, a "25 mm" cap fits standard 25 mm OD PVC pipe. If you're unsure, measure the outside diameter of your pipe with calipers and select the matching size from the variant options above. Do not measure the inner bore — PVC fittings are sized by OD.

These PVC end caps are suitable for both DWV (drain-waste-vent) and cold water pressure applications when solvent-welded with PVC cement. For pressure-rated use, always bond with an appropriate PVC solvent cement and allow full cure time before pressurizing. For temporary capping during pressure tests, a friction fit is sufficient for short durations at low pressure.

Yes. Rigid PVC is inherently corrosion-free and resistant to chlorinated water, mild acids, alkalis, and most common household chemicals. These caps will not rust, pit, or degrade in typical plumbing, irrigation, or aquarium environments. They are not recommended for use with solvents, concentrated acids, or high-temperature fluids above approximately 60 °C (140 °F).

No special tools are needed. For a temporary seal — such as during a pressure test — simply push the cap firmly onto the pipe end. For a permanent, watertight bond, apply standard PVC solvent cement to both the pipe end and the inside of the cap socket, then push together and hold for 30 seconds. Follow the cement manufacturer's cure time before pressurizing.

The three color options serve both aesthetic and functional purposes. In multi-zone irrigation or plumbing systems, different colors can be used to visually identify separate circuits at a glance — for example, Blue for cold water, Gray for drainage, and White for general use. They can also be selected simply to match or contrast with existing pipework in your installation.

These caps are sized to metric nominal OD dimensions (20 mm, 25 mm, 32 mm, etc.), which are the standard for most PVC pressure and DWV pipe systems. Imperial-sized pipe (e.g., 1", 1.5", 2") may have slightly different ODs. Always verify your pipe's actual outer diameter before ordering to ensure a proper fit.

Yes. Rigid PVC is a widely used material in aquarium and pond plumbing due to its non-toxic, inert properties in contact with fresh and salt water. These end caps are suitable for capping sump overflow ports, return line branches, and other PVC fittings in aquarium systems. Ensure all solvent-welded joints are fully cured and rinsed before introducing water to a live system.
