⚡ At a Glance
- • Sealing Performance: High-temperature silicone rated -50 to +225°C, with intermittent tolerance to 260°C, suited to pipe diameters 110–170mm
- • Best for: Roofers, heating engineers and DIYers fitting vent, flue or soil pipe flashings on low-pitch roofs
- • Not ideal for: Pipes outside the 110–170mm range or roofs steeper than 18 degrees
Base dimensions measure 280mm x 280mm and the flange suits 110–170mm pipe diameters. Roof pitch suitability covers 0 to 18 degrees and the silicone handles wide temperature ranges.
Weatherproof sealing, with high-temperature silicone
High-temperature silicone is rated from -50°C to +225°C and can tolerate intermittent spikes to 260°C, allowing the rubber flange to remain stable under thermal stress. The material forms a close fit around irregular pipe profiles without hardening at low temperatures.
A weatherproof seal protects pipe penetrations across seasonal extremes, keeping flues and vents weathertight through hot exhausts and cold winters.
Flexible fit for many pipes, with 110–170mm diameter range
The design accommodates pipe diameters from 110mm to 170mm and sits on a 280mm x 280mm base that can be trimmed for a neat finish. Compatibility covers common vent and soil pipe sizes used in domestic and light-commercial work.
One flashing works for several pipe sizes on site, reducing the need to carry multiple stock items and speeding up installations.
Quick installation and trimming, with user-friendly rubber
Soft yet robust rubber material cuts cleanly with a utility knife and conforms to the roof surface, while the flat base helps achieve a tidy seal. User feedback highlights ease of trimming and straightforward fitting.
Fast to fit and easy to modify, the flashing suits busy tradespeople who need reliable, quick-to-install roof penetrations.
