2 PACK Silicone Coupler/Reducer-1.50 " to 1.75 " ID Straight Silicone Hose-4 Ply

2 Pack Silicone Coupler/Reducer 1.50" to 1.75" ID Straight Hose

This two pack of straight silicone reducer couplers steps from 1.50 inch to 1.75 inch inside diameter, joining mismatched intake or charge pipe sections with a flexible, clamp-ready connection.

Overview

These silicone couplers are 4 ply reinforced reducers that bridge a 1.50 inch to 1.75 inch inside diameter gap in intake and intercooler plumbing. Each silicone hose handles boost pressure and engine bay heat while flexing to absorb vibration and minor misalignment. Sold as a two pack, they suit anyone building or repairing forced induction piping.

Built For Performance

• 4 ply reinforced silicone construction resists pressure expansion and vacuum collapse
• Stepped reducer design transitions between 1.50 inch and 1.75 inch inside diameters
• Straight hose body fits inline between two rigid pipe sections
• Silicone material tolerates high engine bay temperatures better than standard rubber
• Two piece pack supplies both sides of a build or a spare for future service

On-The-Job Use

• Joining intercooler charge pipes of different sizes
• Bridging intake tubing on turbo or supercharged builds
• Replacing cracked or heat hardened factory couplers
• Custom plumbing where pipe diameters change mid-run

Specs At A Glance

Good To Know

Q: Are hose clamps included? A: No, clamps are not part of this listing, so source clamps sized for each end before installation.

Q: Which end is which size? A: The coupler steps from 1.50 inch inside diameter on one end to 1.75 inch on the other, so measure both pipes before fitting.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
