Mishimoto Silicone Reducer Coupler 45Deg 2.5-3.25in Black

Silicone reducer coupler for transitioning 2.5" to 3.25" plumbing at a 45-degree angle, providing a reliable, application-ready connection for coolant and air passage systems.

This Mishimoto Silicone Reducer Coupler 45Deg 2.5-3.25in Black is designed to simplify routing where a compact 45° offset and a change in diameter are required. The coupler is intended for use in both coolant and air passage systems, offering flexibility when adapting plumbing runs or joining mismatched tubing sizes.

• 45° transition — Enables smooth directional changes in tight spaces; useful where a gradual angle reduces stress on hoses and fittings.
• 2.5" to 3.25" step-down — Provides a direct, single-piece solution for joining different-diameter tubing without multiple adapters.
• Silicone construction — Suitable for use in coolant and air passage systems as specified; silicone material provides flexibility for secure clamping and vibration resistance.
• Black finish — Low-visibility appearance for clean installations in visible engine-bay or bay-adjacent locations.

Why this matters: a dedicated 45° reducer coupler reduces the number of joints and clamps required, simplifying installation and minimizing potential leak points when integrating plumbing runs in complex systems.
