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

no clamp needed, fast hook on and stay secured in place. So far no leak yet. Love the sleek design and polished materials

Well made and works great.

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

Works perfect to adapt my hose!

Item delivered quickly. Item exactly as described.

I like every thing about it. The I.D. is the same the whole length. Machining is smooth and well done. Standard 3/4 and 5/8 heater hoses fit perfectly.

I used to purchase to plastic couplers from auto parts store but they fail every 3-4 years sending plastic chunks and bits into my water pump and cooling system, this is much better material and will probably outlive the Jeep and me.

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

Used this for adapting a aux heater water pump on an Ford Explorer. Works fine, no problems.

Good adapter
