Assenmacher Specialty Tools FZ 35 A Cooling System Adapter

Very nice piece from AST. Can verify fits F150 and Super Duty. A few dollars more than truck prices, but all metal. I'm a sucker for all metal

The green and silver piece came apart on my first use. Thankfully I had a press to put the two pieces back together. Never had that problem again (after 100 plus uses) The threads are a hair off so it looses pressure very slowly. Lastly, the inside diameter is a hair small so your pressure tester does not lock in place but still makes an airtight seal. All in all, it does what I need it to but isn't just right. It feels like a knockoff.

A little more than I wanted to spend but Matco does not provide warranty on their adapters past one year (no moving parts you would think it should be lifetime)this was less than replacing it through the tool truck. Let's see how long it lasts

Excellent bang for the buck!

Great item from AST, same quality but better price then name brand tool truck items.

Works great.

Top notch coolant adapter for pressure testing and filling. Seals everytime no issues.

I am slowly purchasing these due to the durability and craftsmanship. These are great coolant tester adaptors.
