Product Information

Full details

The Lindab Gutter Union 150mm in Graphite is designed for homeowners and professional contractors looking to create a secure, permanent connection between lengths of 150mm steel guttering. Its primary benefit is the integrated, self-sealing rubber gasket that provides a reliable, watertight joint in the Lindab Rainline system; however, users should note that the system requires specific silicone lubrication during installation to ensure a smooth, long-lasting fit.

FAQs

Is this union compatible with 150mm plastic guttering?

No, this component is specifically engineered for the Lindab Rainline steel guttering system.

Do I need to apply additional sealant?

No, the built-in rubber gasket is designed to create a watertight seal. Only silicone spray for lubrication is required.

Will the graphite finish fade over time?

The steel is coated with a finish designed to resist UV damage and discoloration, ensuring long-term color stability.

Can this be used on a roof with a steep pitch?

Yes, provided the overall gutter system is correctly installed and supported according to the manufacturer's guidelines.

Is any maintenance required?

The system is maintenance-free; however, regular debris removal is recommended to keep the gutters clear.

Troubleshooting

Joint feels difficult to snap together

Ensure the rubber gasket has been sprayed with silicone lubricant to reduce friction.

Water dripping from the underside of the union

Check that the gutter ends are cut square and are free from burrs; ensure the union is centered correctly over the joint.

Pros and Cons

Pros

  • Watertight seal prevents common gutter joint leaks
  • High-durability steel resistant to rust and fading
  • Maintenance-free operation once installed
  • Seamless aesthetic compatibility with modern and traditional designs
  • Significantly longer lifespan than plastic guttering

Cons

  • Requires silicone spray on seals for optimal assembly
  • Only compatible with the specific 150mm Lindab Rainline system
  • Steel material is heavier than lightweight plastic alternatives

Setup, Compatibility & Care

To ensure a proper installation, always clean the ends of the gutter lengths to remove any debris or metal filings before connecting them. Prior to clicking the union into place, spray the rubber seals with a silicone-based lubricant to reduce friction and improve the seat of the gasket. This component is strictly compatible with the 150mm Lindab Rainline steel guttering system. For long-term care, the system is essentially maintenance-free; however, it is good practice to clear leaves and debris from the guttering annually to ensure free flow and prevent water pooling, which can cause excessive stress on all joints.
