Full details

The Osma RoundLine Gutter Union is designed for homeowners and contractors working with the 112mm RoundLine rainwater system who need a reliable, watertight joint for their gutter runs.

Extended Product Information

FAQs

Is this union compatible with other gutter brands?

No, this is specifically designed for the Osma 112mm RoundLine system and may not provide a watertight seal with other brands.

What is the maximum roof area this can support?

When used with a single 68mm downpipe, this system can accommodate a roof area of up to 163m².

Do I need sealant to install this?

The union is designed with wide, retained seals, meaning no additional silicone sealant is required for a standard installation.

How do the expansion marks work?

The marks indicate the precise point to which the gutter should be inserted based on the temperature during installation to allow the pipe to move without leaking.

Is this product UV resistant?

Yes, as it conforms to BS EN 607:2004, it is manufactured to withstand outdoor exposure, including UV radiation.

Troubleshooting

Water leaking at the joint

Check that the gutter lengths are pushed in far enough to reach the seals but remain within the expansion allowance. Ensure the seals are not pinched or covered in grit.

Guttering buckling or popping out of the union

Verify that you have allowed enough space for thermal expansion using the internal marks. If the gutter is too long for the calculated temperature, it will push against the union.

Pros and Cons

Pros

Integrated expansion guides prevent buckling
High-quality retained seals ensure watertight integrity
Engineered to BS EN 607:2004 standards
Easy to install for both DIY and professional users
Durable finish in a classic brown color

Cons

Limited to 112mm RoundLine gutter profiles
Requires proper measurement for thermal gaps to function effectively
Color matching is specific to the Osma Brown range

Setup, Compatibility & Care

To install, ensure the gutter ends are cut square and deburred to prevent damage to the internal seals. Push the gutter lengths into the union up to the prescribed expansion marks, which allow for the natural movement of the plastic as the temperature changes.

Compatibility: Compatible exclusively with the 112mm Osma RoundLine gutter system. It is not designed for square-profile gutters or other manufacturers' systems.
Care: Periodically inspect the joint for debris buildup. During seasonal gutter cleaning, gently wipe the interior of the union to ensure the seals remain free of grit or leaves that could impede drainage.
Maintenance: Avoid using harsh chemical solvents on the unit, as these can degrade the plastic and the integrity of the seal.
