Double socket with restrictor, InstalPlast PVC 110 mm

InstalPlast double socket with restrictor for 110 mm PVC drainage pipes. The fitting joins two pipe ends securely and the integrated restrictor controls insertion depth to ensure consistent connections. Made from rigid PVC-U, it is intended for external gravity drainage and sewer systems handling wastewater with pH 2–12 at temperatures up to +40°C (short-term up to +60°C). The smooth orange-brown surface minimizes scale and sediment build-up.

Advantages

The PVC double socket with restrictor offers high mechanical strength, impact resistance and chemical durability. A silicone-sealed socket provides a tight, reliable joint and simplifies installation. The built-in restrictor prevents over-insertion of pipes, ensuring correct alignment and consistent sealing without additional tools.

Suitable for

• External underground gravity drainage and sewer systems
• Household and light commercial wastewater lines
• Pipe runs under roads, embankments or in culverts

How to use

Ensure pipe ends are cut square and clean.

The socket connection creates a tight joint; follow local codes for additional fastening or bedding when installing underground.

Usage recommendations

Use the double socket with restrictor for non-pressure external drainage applications only. Avoid continuous exposure above specified temperature limits and follow standard installation practices for underground sewer and drainage systems to maintain longevity and leak-free performance.
