3.00" to 3.50" 90 Degree Silicone Reducer Hose — 3-Ply Black
Stepped silicone hose transitions coolant or intake flow from 3-inch to 3.5-inch diameter with a 90-degree bend. Three-ply construction handles boost and coolant pressure without ballooning or collapsing. Black exterior resists UV and oil degradation in engine bay conditions.
Key Features
- Step-down taper — Matches different diameter piping without adapters or custom fabrication
- 90-degree elbow — Routes flow around tight corners without kinking or dead zones
- 3-ply reinforcement — Resists collapse under vacuum and holds shape under pressure cycles

Frequently Asked Questions
Will this hose work for both coolant and boost applications?
Yes. Silicone construction tolerates coolant loops and turbo/supercharger intake charge air without degradation. If you're running boost, confirm your system pressure stays within silicone's safe operating range for your specific setup.
Do I need hose clamps?
You'll need clamps rated for the hose diameters you're connecting to — typically 3-inch and 3.5-inch band clamps. Clamps are not included, so source them separately based on your plumbing layout.
Can I cut or modify this hose to fit a tighter space?
Cutting silicone hose is straightforward, but you lose the 90-degree geometry and bend radius engineering. If your space requires a different angle or length, custom hose from a local fabricator often costs less than trial-and-error modifications.
