Good quality part for blocking off the heater core. Had no problems with installation and all hoses clamped up nicely.

It's made of metal which is nice and it fit my '98 Mercury grand marquis perfectly. It took maybe 15 minutes total to put on and works as intended

This was an easy temporary fix for my leaky heater core. Pulled the hoses off the heater core, picked the right size fittings, and attached to the heater hoses. I knew this going in but for those who may not, you will not have any heat after this. So don't do this during the winter. The purpose is to allow you to keep driving without breathing in toxic coolant fumes until you can get the heater core replaced.

Looks well made. Doesn't take up a lot of room in the jeeps tool kit. Got it for emergency repair on the trail. Inexpensive piece of mind
