These worked great to adapt some braided lines to my transmission cooler (the one built into the radiator) on my 2000 Silverado. Was able to use these to run braided line from the trans to radiator cooler then to an aftermarket unit all in series. Solid fittings snapped right in.

I have a 2002 silverado with the larger 6.0 liter HD radiator installed. The fittings worked great for me (no leaks).

Ended up having to replace with a custom made line because the pressure side couldn't actually hold any pressure and popped the tube inside twice.
