Our aluminium donuts are used to gain a tighter radius bend than our 45/90 degree bends. Primarily used for tight/compact installations which make it perfect for that custom intercooler, radiator pipe work or exhaust systems. These donuts will not corrode or rust like coated or painted steel and are much lighter than stainless

They have a 2mm wall thickness, depending on stock they can be a brushed or bright anodized finish

This donut once welded can be cut into different pipe angles. Unwelded option is also available
