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

So far so good

As described and works perfect!

This high-quality adapter was exactly what I needed to adapt my Audi heater hoses to the LS water pump in my swap project. ICT Billet always delivers the goods.

Used on auto coolant system

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.

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 like a charm for my Cherokees cooling system

The part is as nice as the picture and description! Very happy.

Good quality.works great.

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