Our take on the Turbosmart 50m Roll -4mm Vac Tube -Black

The Turbosmart 4mm Vacuum Hose is a 50-meter roll of black silicone vacuum tubing for automotive boost and vacuum lines. Its 4mm bore suits boost gauges, wastegates, blow-off valves and boost controllers, where a firm, heat-resistant line matters more than a soft one. Against generic parts-store rubber hose, silicone holds its shape under heat and won't harden or crack as quickly, but it costs more and can collapse if bent sharply. The long roll suits shops and multi-car owners who cut lines to length rather than buying short pre-cut pieces.

Questions and answers

What is this hose used for?
It is vacuum and boost line for cars: boost gauges, wastegates, blow-off valves and boost controllers. The 4mm bore suits low-flow signal lines rather than fuel or coolant.
Is silicone better than rubber vacuum hose?
Silicone handles engine-bay heat without hardening or cracking as fast as plain rubber. It is softer and can kink more easily, so route it with gentle bends or add clips at sharp turns.
Will 4mm hose fit my boost gauge?
Most boost gauges and wastegates take 4mm line, and this is the common size for those fittings. Check your gauge or valve barb before cutting; larger barbs need a bigger bore.
Does it come with clamps or fittings?
No. The roll is hose only, so buy small hose clamps or zip ties separately to secure the ends.
How much hose do I need for a typical install?
A boost gauge run usually takes a meter or two, and wastegate or blow-off valve lines take less. The 50-meter roll is aimed at shops or several cars, so cut only what you need and store the rest.
