1.50" to 1.75" 90 Degree Silicone Reducer Hose - Blue 3-Ply

What size clamps do I need?

You'll need clamps sized for both ends — a 1.50" band clamp on the inlet side and a 1.75" band clamp on the outlet. Standard worm-gear or t-bolt clamps work fine. Grab a pair rated for high-temp silicone to avoid slippage.

Can I use this for both coolant and boost lines?

Yes. Silicone handles coolant temps and boost pressure without issue. Just verify your clamp torque specs in your service manual and don't over-tighten—silicone can deform if you crush it.

Does this come with the barbed fittings or end adapters?

Hose only—no fittings included. Measure your existing banjo bolts or hard-line adapters and order matching push-on barbs or threaded adapters separately if you need them.
