Exhaust Gas Recirculation Tubes

BOA Exhaust Gas Recirculation
BOA Exhaust Gas Recirculation

EGR pipes ensure the transportation of hot exhaust gas back from the exhaust line to the intake air flow and do so in the high pressure stream as well as the low pressure one.

The 1.4541, 1.4571, 1.4828 stainless steels are particularly adapted to peak temperature up to 900°C for these types of applications. They avoid corrosion, pipe deformation under temperature...

The corrugations located in the bends or on the strait portions provide flexibility in the pipe, improve durability, facilitate pipe assembly, and reduce weight by using thinner pipes.

Flange, special fittings, o-ring, gasket according the customer or BOA standards and experience will ensure a low connection leakage and benefit for Euro 4, 5, 6 regulation norms.

The BOA Group offers EGR pipes from diameter 20 to 32 mm and wall thicknesses from 0,2 to 0,5 mm.

Turbo Charger Oil Drain Pipes

BOA Oil Drain Pipe

The use of BOA stainless steel tubes insure reliability in harsh environments associated with high temperature applications and the latest Euro standard equivalent.

Largely resistant to the thermal radiation of the turbocharger, they provide a sustainable alternative to rubber hoses.


The 1.4301, 1.4541, 1.4571 stainless steels are particularly effective for applications with temperatures up to 600°C. They resist corrosion, pipe deformation under temperature...

The BOA Group can provide a connecting solution for virtually any kind of leakage requirements. BOA is also able to adapt the pipe design to any special customer requirement.

Turbo Charger Oil Drain Pipes are available in diameters from 14,6 to 20 mm, with wall thickness either 0,25 or 0,3 mm.

Air Tubes

BOA Air Tube

The last gasoline direct injection engine generation is particularly compact and exposed to high temperatures. In some cases, the use of rubber or plastic pipes is no longer possible.

The use of BOA stainless steel tubes constitute a robust alternative combining lightweight and flexibility by using grades 1.4301 and 1.4541.

As these pipes are often visible for the end customer, the shiny surface of metal is a real design benefit.

The BOA Group can provide solutions with integrated plastic quick connectors and any kind of specific fittings.

The BOA Group offers air tubes with diameters from 14,6 to 32 mm and 0,2 to 0,5 mm wall thicknesses.
