PVC stopper InstalPlast 160mm, InstalPlast 160 mm PVC plug for pipes and openings

InstalPlast PVC stopper 160 mm is a plastic plug designed to close or seal pipe ends and openings with a 160 mm diameter. It is intended for use with external drainage PVC-U pipes and fittings in non-pressure wastewater systems with pH 2–12 and temperatures up to +40°C (short-term up to +60°C). Made from rigid PVC-U, the stopper matches the orange-brown colour of sewer pipes, offers a smooth surface that reduces scale and deposits, and integrates with the pipes’ socket and silicone-sealed gasket connection for a tight, trouble-free fit.

Advantages

The PVC stopper provides a simple and durable method to block water flow, prevent debris entry and enable pressure testing or maintenance of drainage lines. Being made of non-plasticized PVC-U ensures high strength, impact resistance and chemical durability. The product’s design works with standard socket-and-gasket connections, ensuring a reliable seal and easy installation.

Suitable for

• Sealing pipe ends and openings with a 160 mm diameter
• Temporary or permanent closure during plumbing, construction, and renovation
