B-G Racing Dual Layer Air Ducting Hose — Black

B-G Racing Dual Layer Air Ducting Hose — Black (per metre)

The B-G Racing Dual Layer Air Ducting Hose in black is a high-temperature flexible ducting hose designed for motorsport brake cooling, radiator cooling, and intercooler ducting applications. The black dual-layer construction offers the same high-temperature performance as the B-G Racing orange ducting hose — the black finish suits installations where aesthetics matter or where the hose is visible in the engine bay or wheel arch.

Available in continuous lengths up to 4 metres (13.1 ft) per order, there is ample hose to route from the front splitter or bumper duct to the brake caliper or radiator inlet, with enough to trim to length on both ends. Available in four diameters to suit a wide range of applications from kart brake cooling through to large-diameter radiator ducting on circuit and rally cars.

Note: this is a bulky item and freight may vary to different locations.
Hose is priced per metre and available in continuous lengths up to 4 metres.

Frequently Asked Questions

Is the black hose the same temperature rating as the orange B-G Racing ducting hose?

Yes — the black dual-layer hose has the same high-temperature rating as the B-G Racing orange ducting hose. Both are suitable for direct brake cooling applications where the hose is exposed to significant heat.

What diameter do I need for brake cooling?

For most circuit cars, 2" (51mm) is the most common brake cooling duct diameter. Larger cars or those with significant brake heat (GT, touring car, endurance) may benefit from 3" (76mm). Karts and small formula cars typically use 1.5" (38mm).

How is the hose priced and what length can I order?

The hose is priced per metre. You can order in continuous lengths up to 4 metres (13.1 ft) per order. It can be cut to suit your installation with a sharp knife or scissors.
