Product Information

Full details

The FloPlast Half Round Gutter Internal Stopend (112mm, Grey) is an essential component for homeowners and contractors looking to securely cap off gutter systems at internal fittings. Its primary benefit is providing a watertight, professional finish to gutter runs, though users should ensure their existing gutter system is compatible with the 112mm half-round profile before purchase. Constructed from robust PVC-U, this stopend integrates seamlessly with existing FloPlast or standard half-round guttering to prevent leakage and ensure water is directed efficiently toward downpipes.

Extended Product Information

FAQs

Is this stopend compatible with other brands?

It is designed for 112mm half-round systems; while it may fit other standard 112mm profiles, FloPlast recommends using it within their own range for the best seal.

Do I need glue for the installation?

No, the component features a pre-lubricated seal that provides a watertight fit without the need for solvents or adhesives.

Can this be painted?

Yes, but it is manufactured in a standard grey finish designed to be maintenance-free and UV-stable.

What does 'Internal' refer to in the name?

Internal refers to the stopend fitting inside the gutter profile, rather than an external end cap that covers the outside rim.

Is this product fire resistant?

Yes, it is manufactured from non-ignitable PVC-U.

Troubleshooting

Water leaking from the connection point

Check if the stopend is fully seated and the internal seal is free of grit or debris. Ensure the gutter edge is not deformed.

Difficulty sliding the stopend onto the fitting

Ensure the fitting is the correct 112mm size. Apply a small amount of silicone lubricant if the factory seal feels dry, though this is rarely necessary.

Pros and Cons

Pros

  • Durable and weather-resistant PVC-U construction
  • Pre-lubricated seal ensures a quick, leak-free installation
  • Matches standard half-round guttering systems
  • Provides a clean and finished aesthetic to pipework

Cons

  • Compatibility limited strictly to 112mm half-round profiles
  • Cannot be used on square-line or deep-flow gutter systems
  • Requires proper alignment to ensure the seal sets correctly

Setup, Compatibility & Care

To install, ensure the cut end of your gutter or fitting is clean and free of debris. Slide the internal stopend onto the fitting, ensuring the pre-lubricated seal sits firmly against the gutter wall. It is compatible with 112mm FloPlast half-round systems and should not be forced onto incompatible profiles. For maintenance, periodically clear the gutters of leaves and debris to prevent blockages that could cause water to pool against the stopend. While the material is UV-stable, a quick rinse with warm soapy water during annual gutter cleaning is sufficient to maintain its appearance.
