90 Degree Reducer Elbow 2in I.D. x 1.75in I.D.

The 90 Degree Reducer Elbow 2in I.D. x 1.75in I.D. is a precision silicone coupler designed for custom automotive intake, turbo, and coolant system modifications where diameter step-down transitions are required. This reducer elbow serves mechanics and enthusiasts building high-performance engine bay configurations, intercooler plumbing, or custom air induction systems that demand reliable, flexible connections between mismatched tube sizes. Its 90-degree geometry makes it essential for tight-fit installations where straight runs aren't possible.

Constructed from premium black silicone, this coupler delivers exceptional heat and coolant resistance—critical for turbo applications, intercooler piping, and modern EFI engine bays where underhood temperatures exceed standard factory specifications. The dual I.D. design transitions smoothly from a 2-inch inner diameter to a 1.75-inch inner diameter, minimizing turbulence and pressure loss while maintaining structural integrity under boost and thermal cycling. Silicone construction provides superior flexibility compared to rigid aluminum or plastic alternatives, allowing the elbow to absorb vibration and engine movement without cracking. Each unit measures 4 inches per leg length, with overall dimensions of 10.63 x 2.2 x 12.6 inches, fitting compact engine compartments without excessive obstruction.

This reducer elbow is ideal for turbocharger intercooler piping, custom intake manifold builds, vacuum line consolidation, and any plumbing application requiring a stepped-diameter 90-degree transition. Installation requires hose clamps at both ends—standard 2-inch and 1.75-inch hose clamp sizes are recommended for secure sealing. The silicone's inherent flexibility makes it forgiving during installation on tight bends and around engine accessories, while its resistance to engine oils, coolant, and thermal shock ensures long-term durability in demanding street and track applications. Verify inlet and outlet sizes match your existing tubing before purchase to ensure proper fitment.
