Product Information
Full details
The Osma RoofLine 150mm gutter union is designed for commercial and industrial contractors or property owners requiring a reliable, weather-tight connection for large-capacity rainwater systems. Its primary benefit is the inclusion of built-in expansion markings, which simplify the process of allowing for thermal movement during installation; however, it is strictly intended for use with the 150mm half-round system and is not backwards compatible with smaller domestic gutter sizes.

FAQs
Can I use this union on 112mm guttering?
No, this union is specifically designed for 150mm half-round gutter systems and will not provide a secure fit for 112mm guttering.
Why are there markings on the inside of the union?
The markings are expansion indicators. They show you exactly how far to slide the gutter into the union to allow for thermal expansion and contraction.
Does this union work with downpipes?
The union itself connects gutter lengths; however, it is designed to be fully compatible with 110mm OsmaSoil downpipe systems in the overall rainwater design.
What standards does this product meet?
This product conforms to the BS EN 607:2004 standard for gutter and gutter accessories.
Is this product suitable for coastal locations?
Yes, the materials are chosen for industrial and commercial durability, making them resistant to typical environmental stressors, though regular cleaning is recommended.
Troubleshooting
Gutter sections do not fit into the union.
Ensure you are using the correct 150mm half-round profile and remove any sharp plastic burrs from the cut ends of the gutter.
Water leaking at the union joint.
Verify that the gutter sections are inserted past the internal seals and that they are aligned with the expansion marks to prevent tension on the joint.
The joint appears misaligned.
Check that the supporting brackets are installed at the correct height and spacing, as misalignment of the support system will affect the union connection.
Pros and Cons
Pros
- Integrated thermal expansion markings ensure accurate installation.
- Specifically designed for high-capacity industrial rainwater systems.
- Certified to BS EN 607:2004 safety and quality standards.
- Seamless integration with existing Osma 150mm and 110mm drainage hardware.
Cons
- Not compatible with standard 100mm or 112mm domestic guttering.
- Requires specific Osma brackets for optimal alignment.
- Size requires more space for storage and handling compared to residential parts.
Setup, Compatibility & Care
To ensure a long-lasting installation, check that the gutter ends are cut cleanly and free from plastic burs before inserting them into the union. This component is fully compatible with Osma top brackets, side brackets, and rise-and-fall brackets within the 150mm range. For maintenance, periodically inspect the union to ensure that debris has not obstructed the joint and that the gutter sections remain aligned with the expansion markers. If the system is installed in an area with high temperatures, perform these checks annually to verify that the thermal expansion gap remains within the recommended parameters.
