ICT Billet 5/8 to 3/4 Inch Hose Barb Splice Coupler Reducer Repair Fitting Adapter Connector Radiator Coolant Intercooler Heat Exchanger Fluid Designed & Manufactured in USA Bare Aluminum AN627-11A

The reducer arrived on time, well packaged, and as advertised. Quality materials and construction. No issue.

When you have an older vehicle where the OEM style hose is no longer produced anywhere and that hose reduces from a 3/4 ID to a 5/8 ID, you have to adapt with a pair of different ID diameter hoses, and then splice together which this item works perfectly for.

Worked like a charm for my Cherokees cooling system

Good Product

Using for heater hose reduction

Item delivered quickly. Item exactly as described.

Very difficult to assemble and positively clamp hose ends to this reducer /adapter. Had to replace rubber hoses, new clamps and double clamp each end to finally seal up the connection. I would like to see this part with more aggressive barbs /ribbing to better bind with hose ends; this may help seal up to prevent leaks.

Worked perfect for my heater hose havent ran the engine much yet but looks like a quality fitting

Came as ordered and used it on my car’s heater hose carrying coolant to the heater core. Has worked fine so far and both sizes of hose fit well. Only issue was that coolant vapor could still escape the barbs, I saw lots of gas coming out of the coupling. Nothing a quick hose clamp couldn’t solve though. Good all around.

Delivered on time and the big plus, its made in the USA.
