Extra 45° bends for your Bendlabs header mockup kit. The workhorse angle for routing primaries around obstructions and feeding runners into a collector at a sensible sweep.
Modelled to 1.75" OD mandrel bent exhaust tube (44.45mm), so every block matches the true outside diameter and centreline radius of the tube you will actually weld. Magnetic ends snap to any other Bendlabs block of the same size.
Works with the 1.75" tube Starter, Builder and Workshop kits
On tube, D refers to the actual outside diameter, so these radii differ from those in our NPS schedule pipe kits. Blocks will not connect across sizes.
