PVC plug InstalPlast 110 mm Model 8011172 — threaded closure for 110mm pipes

PVC plug for external drainage works, 110 mm. The plug is intended for sealing or temporarily capping 110 mm drainage and sewer pipes in external gravity sewer systems. Made from unplasticized PVC (PVC‑U), the material offers high strength, impact resistance and chemical resistance. The smooth surface reduces scale and sediment buildup. The product is compatible with standard orange‑brown sewer pipes and provides a threaded closure suitable for installation, removal and short‑term pressure or leak tests.

Advantages

The PVC threaded plug provides a tight, reliable seal for 110 mm pipes and is easy to install and remove. Its PVC‑U construction ensures durability, impact resistance and resistance to a wide range of chemicals. The smooth exterior reduces deposits and facilitates cleaning, while the threaded design allows secure temporary closure during construction, repair or testing.

Suitable for

• Sealing or temporarily capping 110 mm external drainage and sewer pipes
• Construction and repair works on underground non‑pressure sewer systems
• Leak and pressure testing of 110 mm drainage pipelines
• Sites where corrosion‑resistant plastic closures are required

Key specifications

• Material: unplasticized PVC (PVC‑U)
• Nominal pipe diameter: 110 mm
• Type: threaded closure / plug for drainage pipes
• Colour: orange‑brown (compatible with standard sewer pipes)
• Operating temperature: up to +40°C continuous, short‑term up to +60°C

How to use

Insert the threaded PVC plug into the open end of a 110 mm drainage pipe and turn until seated to form a secure closure. Ensure the pipe end is clean and free of debris before installation. The threaded design allows straightforward installation and removal by hand or with a suitable wrench if required. Use the plug for temporary sealing during construction, maintenance or testing and remove when operations are complete.

Usage recommendations

Use the plug only with compatible 110 mm PVC sewer or drainage pipes and observe the specified temperature and chemical exposure limits. For long‑term installations or continuous elevated temperatures, select components rated for those conditions. Inspect the sealing surface before reuse to ensure a reliable closure.
