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

Itll be used to bypass a leaking heater core on my antique car so I can drive it w/o all the glass fogging up. It looks well made and precisely machined. Its shorter than the Dorman connector which may make the hose connections easier in the available space.

Item delivered quickly. Item exactly as described.

5/8” x 3/4” adapter. Good quality, fast shipping.

Used this to bypass my heater core on my 96 Cherokee and 98 Grand Cherokee. Has both ends that I need. I preferred this route rather than just using one size hose and make it fit.

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.

Used on auto coolant system

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

I ordered two barbed fittings and got one barbed and one threaded. I only ended up needing one so I didn’t bother refunding but solid fittings just please send the right ones we order.

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

As described and works perfect!
