Mishimoto Silicone Reducer Coupler 45Deg 2.25-2.5in Black

Mishimoto Silicone Reducer Coupler 45Deg 2.25-2.5in Black serves as a 45-degree silicone transition coupler designed to join 2.25" and 2.5" hose diameters while providing durable, heat- and pressure-resilient service for coolant and air passage systems.

This coupler is part of Mishimoto’s expanding line of silicone couplers, intended for projects that require a reliable angled connection where straight couplers will not fit. The 45-degree geometry eases routing in constrained engine bays and the reducer profile allows transition between two common hose sizes without fabricating custom tubing.

Functional benefits

• 45-degree transition — simplifies hose routing where space or clearance prevents straight couplers, reducing the need for clamps or joints that add potential leak points.
• Reducer profile (2.25" → 2.5") — enables direct connection between mismatched hose diameters without custom fabrication, saving installation time.
• Silicone construction — suitable for use in both coolant and air passages as specified, providing the material compatibility expected from Mishimoto silicone components.
• Mishimoto product lineage — part of a broad, expanding family of silicone couplers designed to make selection easier for performance and maintenance projects.

For technicians and fabricators, this coupler offers a straightforward, OEM‑style way to route and join hoses in confined areas while maintaining system integrity for coolant and intake/air pathways.
