The Lindab 85-degree conical downpipe bend is an essential component for professional installers and homeowners managing steel rainwater systems who need to navigate complex building facades. This fitting excels at creating clean, secure offsets or swan-necks in downpipe runs, ensuring efficient water drainage; however, it requires precise measurement and cutting of intermediate pipe sections to achieve the perfect angle for your specific wall clearance.

No, this product is specifically manufactured for 75mm steel rainwater systems and will not provide a secure fit for standard plastic piping.
Typically, the precision-engineered male-female connection is sufficient to prevent leakage, but you may use a neutral-cure silicone sealant if you prefer extra reinforcement.
You need two bends joined by a small section of 75mm downpipe. The length of the middle pipe determines the depth of the offset.
Yes, if you need to match a specific house color, you can use a high-quality metal primer and exterior paint over the existing finish.
You will need a hacksaw or pipe cutter for adjusting lengths, a file to deburr cut edges, and potentially a drill/driver if you choose to secure joints with screws.
The fitting is designed for a friction fit, but if it feels loose, secure the connection with a stainless steel pop rivet or a color-matched self-tapping screw.
Ensure the male end is inserted fully into the female end. If the pipe was cut, ensure the edge is smooth and does not prevent the fitting from seating correctly.
Check if the protective finish was scratched during handling and apply a high-quality exterior metal touch-up paint to seal the exposed steel.
Installation involves sliding the male (tapered) end into the female end of your existing 75mm downpipe or another fitting. Ensure that the crimped end is pointing downwards to keep water flow inside the pipe system. Compatibility is strictly limited to 75mm Lindab steel rainwater pipes. To maintain the system, periodically check for debris buildup at the bend angles. If the black coating is scratched during installation, apply a touch-up paint specifically designed for steel rainwater goods to prevent oxidation. Avoid using harsh chemical cleaners; warm soapy water and a soft cloth are sufficient for exterior cleaning.
