Turbosmart 1.75" to 3.00" Straight Silicone Reducer – Black

A big-step straight reducer joining 1.75" (45mm) pipework to 3.00" (76mm) — the kind of jump you hit mating a small factory inlet or BOV return to a 3" intercooler pipe or intake. Multi-layer reinforced silicone from Turbosmart, rated to 220 PSI and -50 to 170°C, so it won't balloon under boost or go soft in the engine bay. Part number TS-HR175300-BK.

Why Turbosmart silicone

  • Multi-layer reinforced construction with a 5mm wall — holds shape under boost and vacuum, no ballooning or collapse.
  • 220 PSI pressure rating — more than any street or track turbo system will see.
  • -50°C to 170°C temperature range — unaffected by engine-bay heat or cold starts.
  • Smooth internal bore for unrestricted airflow across the step.
  • Resistant to oil, coolant and UV — won't crack or perish like rubber.

Typical uses

  • Adapting a 1.75" throttle body, turbo inlet or BOV return to 3.00" pipework
  • Joining mismatched intercooler or intake pipe sizes in one step
  • Custom turbo, supercharger and intake builds
