Product Description

2.25" to 2.50" 45 Degree Silicone Reducer Hose — 3-Ply Black

Stepped silicone hose that transitions from 2.25" down to 2.50" at a 45-degree angle. Three-ply construction withstands boost and coolant flow without collapsing. Black finish resists UV and oil degradation in engine bay conditions.

Frequently Asked Questions

Do I need hose clamps to install this?

Yes. This hose relies on clamps at both the 2.25" and 2.50" ends to create a sealed connection. Stainless steel clamps rated for silicone hose are recommended for engine bay use.

Can I use this on a coolant line or does it need to stay on boost piping only?

Silicone hose works on either. The 3-ply construction handles both coolant and forced induction applications. Verify your system's operating temperature and pressure stay within silicone limits before running it in extreme conditions.

What if my ports are slightly different sizes than 2.25" and 2.50"?

Silicone hose compresses over clamps, so minor undersizing (like 2.20" ports) can work with proper clamping. Oversizing won't seal. Measure your ports before ordering to confirm fit.
