Better than Factory
This wasn't even an option, way better quality than the factory steel part, and to my surprise it was also half the price. Keep on making amazing parts for are old truck Riffraff, you are killing it.

A million times better than OEM
The OEM nipple is made out of steel while the water pump is made out of aluminum. Odd how the engineers at Ford did not know that when you connect two dissimilar metals and run hot liquid through the fitment the steel part corrodes fiercely. This aluminum upgrade is perfect to solve the electrolysis problem that the engineers apparently did not know about when they designed this engine. Furthermore, the OEM steel nipple is $200 at the dealer. This RiffRaff model is light years ahead of Ford’s.

Best upgrade from stock lower fitting
I upgraded my 2000 f250 which has the 90 degree elbow stock. It's a common leak point for these trucks. This part not only looks great but performs well also. I also got the silicone hose to convert to this fitting from the 90 degree. Installation was simple and it came with all the hardware/gaskets needed to replace it. Riffraff has been my go to for years as they make great quality parts and you get a free pen with every purchase. Honestly the pen is the best too.

Its a No Brainer
This is way better than the OEM steel one. If your originally is rusty you can probably forget it sealing. No leaks so far and I doubt ever.
