Gates Hose Reducer Sleeves

These special rubber sleeves make it easy to connect a coolant hose to a smaller hose nipple. Simply install the sleeve on the undersized fitting, then install your hose on the sleeve and clamp down as you normally would. Great for engine swaps, radiator upgrades, and even installing electric coolant pumps.

Six different sleeve sizes are available. Sleeves are sold individually.

Note: Use only one sleeve -- do not stack two sleeves! If you need to make a larger transition, see our Silicone Reducing Hoses.
