1.25" to 1.50" Silicone Reducer Hose 45 Degree 3-Ply Black
Step down coolant and vacuum lines with a 45-degree silicone reducer built for boost systems and custom cooling loops. Three-ply construction handles pressure and temperature swings without degrading. The 1.25" to 1.50" taper fits mid-range turbo and supercharger plumbing where OEM rubber fails.
Key Features
- 3-Ply Silicone Core - Resists extreme temperature and pressure cycles without cracking or leaking.
- 45 Degree Bend - Angles into tight engine bay spaces where straight hose won't fit.
- Tapered ID - Transitions from 1.25" down to 1.50", reducing turbulence at connection points.

Frequently Asked Questions
Do I need hose clamps to secure this?
Yes. Clamps are not included—you'll need to source appropriately sized stainless steel worm-gear or band clamps for both ends of the hose to ensure a watertight seal under pressure.
Will this handle boost pressure and coolant flow at the same time?
This is built for high-temperature and pressure applications common in turbo and supercharger systems. Confirm your system's PSI rating and coolant temperature before install—3-ply silicone is rated for sustained heat, but your setup determines actual duty.
Can I use this on both coolant and vacuum lines?
Silicone handles both, but vacuum and boost lines have different pressure requirements. Size and confirm the hose matches your system's vacuum draw or boost pressure—don't guess on duty.
