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

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

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

This fitting works! Not much more I can say

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.

Used it to bypass a 98 F-150 heater core. Hoping the aluminum will hold up better than the plastic one it replaced.

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

Well made and works great.
